Hello!
2
Today we're going to be running every size AI locally with the hardware
3
that we have here and see what we can do with it.
4
Hopefully give you guys some ideas for cool things that you can build with local AI too.
5
Let's go!
6
A portion of this video is sponsored by Crusoe.
7
So I'm going to be grouping the hardware that I have here into different classes, different memory classes.
8
So the first class are chips.
9
So chips, as they are called, are literally just chips, just computer chips.
10
They have no operating system, no file system, and no separate memory stick either.
11
Literally everything is just built into these boards.
12
So we try to run an AR model on these.
13
We're not even installing it.
14
We just literally stick it on here, and if it fits, it sits, and we can run it. Or not.
15
And in my case, the smallest one that I have here is an Arduino R4 Uno.
16
It has only 32 kilobytes of RAM.
17
I will put the rest of the stats on screen, which is big enough to fit.
18
Drumroll please.
19
No models.
20
That's right, nothing fits on here.
21
Alas.
22
I actually just got this Arduino Uno R4 as part of a set
23
because I'm trying to learn hardware and it unfortunately does not fit any AI models.
24
But do not be fooled, that does not mean I cannot use this with local AI.
25
I actually can since it has a Wi -Fi functionality so I can connect with some of my bigger devices.
26
But first let's actually talk about something that can actually fit an AI model.
27
Isn't this shocking.
28
It is so tiny.
29
This is the ESP32 S3 and it has 8 megabytes of RAM.
30
I will put the rest of the stats on screen
31
and I got this for around $20 USD although this one does come with a screen
32
so if you get it without the screen you're looking at like two to five dollars.
33
So cheap and you can actually run AI models on here.
34
Two AI models actually.
35
Both of them are called tiny story models which as its name suggests allows you to run tiny stories.
36
Let me show you what it looks click.
37
So this one is the Tiny Stories 1MB model, and then here is the Tiny Stories 3MB model.
38
You can run both of these very comfortably.
39
So yes, it can run the Tiny Stories 260K model and the Tiny Stories 3M model very comfortably.
40
And honestly, this is just the start, getting a model running.
41
You can make it so much cooler by adding on different modules to it.
42
For example, you can make it into a little game called Scrambled vs Not Scrambled.
43
Might be useful if you're learning english grammar
44
and you can attach led lights
45
that represent the mood of the story that's being produced
46
so many cool things that you can do maybe i will make another video showcasing stuff
47
that you can build using these little devices
48
but alas we do not have time in this video
49
so here is a summary slide for the models
50
that we can run on the esp32 and some ideas for ai projects
51
that you can build take a screenshot in the free guide
52
in the description i will also link a little quick start guide for how to get started building
53
so these tiny stories models are only able to do the
54
very basics of predicting the next word in order to form a coherent story
55
which is still very impressive actually given how small it is
56
and you can build some really cool things on top of
57
that too but it is not capable of holding a conversation like a chat
58
and it's not able to run any multi modality models like audio music video
59
or images for that we're going to need to move on to the next class of devices
60
which is the mini computers category
61
this is a raspberry pi the pi 5
62
and this is my personal iphone 16 now these are proper
63
computing devices they run an operating system the raspberry pi runs linux
64
and my iphone runs the ios
65
and they're able to do things like manage memory file systems
66
and run multiple programs and
67
so you can actually have multiple models as long as they fit into these devices
68
but what is really interesting thing is that both of these actually have 8 gigs of RAM, yet they're not able to run the same kinds of models.
69
I'm going to give you guys a quick lesson on AR hardware in just a little bit, but first I want to show you what these guys can do.
70
This is the Raspberry Pi, the Pi 5, and even though it looks very small, it is very mighty because it is a full -blown mini computer.
71
Let me show you what you can do with it.
72
What color is an octopus?
73
Octopuses come in a variety of colors, but they are usually camouflage blending with their surroundings they can be blue green red
74
or even white depending on the species first is using a
75
speech to text ai model called whisper in order to listen
76
to it then i have the quen 3 1 .7b model it's a large language model
77
which is an lm able to interpret it
78
and then come out with a response and then the piper model
79
which is a tiny text to speech model is able to actually answer it out loud on these speakers isn't
80
that crazy i'm able to have full conversations with my Pi by chaining together three different AI models, all on this tiny little device.
81
But wait, that's not all.
82
I can also connect a webcam that grabs a frame, takes a picture, and I can have a tiny visual language model called Moondream,
83
describe it, and the tiny text -to -speech model Piper is able to describe what it sees.
84
Here is the camera, the webcam attached to the Raspberry Pi.
85
The image features a woman sitting in a chair looking at her cell phone.
86
She is wearing a black shirt and is surrounded by a variety of books and other items.
87
There are at least 13 books scattered around the room, some of which are placed on a bookshelf.
88
A backpack can be seen near the woman.
89
and a potted plant is located close to her the scene suggests
90
that the woman might be engaged in reading
91
or studying as she is surrounded by numerous books and other items
92
so yeah you can pretty much run micro to small large
93
language models very easily on the raspberry pi as well as
94
the tiny tier visual language models tiny text to speech models
95
and small but decent speech to text models it does struggle to run mid -sized large language models
96
but if you really want to you kind of can do it
97
and it can kind of barely run small code tier models as well.
98
But it really cannot do image generation, music generation, or video generation.
99
Not actually because a small image generation model wouldn't fit on here.
100
It does.
101
The problem is that it doesn't have any GPUs so it's just like painfully slow to do that.
102
And I will explain GPUs a little bit later.
103
But it does make up for it because you can build using the Raspberry Pi.
104
You can add so many different types of accessories
105
and sensors to your raspberry pi in fact i believe the
106
hugging face robots are running off a raspberry pi as well
107
so yes i'm going to put on a summary slide now including some ideas of things
108
that you can build with a raspberry pi
109
and please do check out the free guide linked below for
110
a quick start guide now let's talk about the iphone 16
111
which also has eight gigs of ram same as the raspberry pi
112
but it is so different for one
113
because it is running on ios apple does limit each app
114
to only be able to use around four to five gigs of ram so even though technically has 8 gigs of RAM, you actually aren't able to run the mid -sized level of models from 7 to 14 beat
115
that you can't do using the Raspberry Pi because like Apple just doesn't let you do it, unfortunately.
116
Also because of Apple reasons, you can't just be like putting on things that you wish onto your iPhone.
117
You have to do it through Apple's official system in
118
which you need to install an app and the app allows you to download, install, and run your local AI models.
119
To get the Gemma 4 model, you need to download the AI Edge Gallery from Google
120
and then download the models locally on your phone this phone
121
is able to run these small plus visual language models meaning
122
it can analyze images of the 1 to 4b range very
123
comfortably since it's only 1 .5 gigs for the image generation you need to download an app called draw things
124
and you can download
125
and run any small image generation models at around the 1b
126
range with no problem like stable diffusion 1 .5 for example
127
is 2 gigs you can run it very comfortably you can also run medium
128
and large speech text models like the whisper large very comfortably
129
and all text -to -speech models too and finally you can run a model called a detection model.
130
It's actually very cool.
131
People don't really talk about it very much for some reason.
132
You can download an app called Ultralytics and download and run the YOLO 11n model.
133
The YOLO 11n model allows you to do object recognition to understand the scene
134
and it's the underlying technology behind all things from facial recognition on your devices to self driving cars
135
because you know you gotta be able to recognize different objects as we're driving.
136
We don't really talk about this class of models very much, these detection models, but they're actually very very useful.
137
Isn't that really cool?
138
I'm going to put on screen now a summary slide including some ideas of things
139
that you can build using your phone with local AI.
140
A small lesson on AI hardware.
141
Now think about a device, any device.
142
It is like a restaurant kitchen.
143
Downstairs we have a walk -in freezer and a storage space.
144
This is where we store all the ingredients, all of the things.
145
Then we have the prep counter.
146
This is where we load up all the ingredients that we need right now for the dish that we want to make.
147
Now let's talk about people who work in the kitchen we
148
have the head chef the head chef is very experienced they can make any sort of dish
149
but just one head chef there is also a brigade of
150
line cooks these line cooks are less experienced less versatile
151
but we have a lot of them that can help us out
152
and finally we have specialized machines bolted to the walls like say an onion machine
153
that only chops onions or like a noodle slicing machine
154
that just automatically sizes noodles i don't know
155
if you guys have seen those before
156
but basically these machines can only do one thing it does
157
that one thing really well and really fast and it uses almost no electricity Now, between the prep counter and the chefs and the cooks and the machines, there is a conveyor belt passageway.
158
This is how we get the ingredients from the prep counter to the chefs, cooks, and machines to process them into, hopefully, a meal.
159
So say, for example, we want to prepare a salad.
160
Well, first, gotta go get all of the salad stuff from the storage in the freezer and put them onto prep counter, like your carrots, lettuce, olives, chicken, other salad stuff.
161
Then we put it on the conveyor belt and it gets passed through
162
and the head chef starts giving out orders tells all the line cooks to be chopping up all the vegetables
163
and also starts up the onion machine to be chopping up onions
164
while he himself is only say like mixing the sauce
165
because that's like the tricky part and then after a few minutes everything comes together
166
and voila we get a salad yay amazing
167
so this is a great analogy for how ai models work on devices
168
so this time what we want to be cooking is a model
169
so we walk down to our freezer downstairs except we call it storage
170
and we grab our model and we put it onto our prep counter which we call the RAM.
171
Then we pass it along the conveyor belt
172
which we call a memory bus
173
and hand it to our head chef called the CPU who
174
then also directs the line cooks to start cooking up parts of the model.
175
The line cooks are called the GPU and also start up the little specialized bolted machines, the onion machine which we call the NPU.
176
And after all this cooking your model is able to produce something like respond to your question of hi how are you?
177
The model then can say hello I am good how are you? okay makes sense
178
so every time we want to be working with the model
179
we need to be going through this entire process of cooking great now you understand the major components of hardware
180
when it comes to ai models however remember the question
181
that we asked earlier why is it
182
that a raspberry pi has 8 gigs of ram
183
and an iphone has 8 gigs rams too but they are
184
so different models run an iphone are much faster
185
and it's able to do image generation while the raspberry pi cannot well
186
that is because these two devices have the same amount of ram
187
which means that the same amount of capacity But they do not have the same amount of bandwidth,
188
which is referring to the conveyor belt between the prep counter and our cook and our chefs.
189
You see, for most large language models, they are bottlenecked by how quickly you can deliver them from the RAM,
190
the prep counter, to the chefs and the cooks and the machines to process the model and get them to be running.
191
On a Raspberry Pi, this conveyor belt, the memory bus, is quite narrow and slow.
192
So it physically takes longer to be able to be processed.
193
And on top of that, a Raspberry Pi only has a CPU without any GPUs or NPUs.
194
So it's basically like having a single head chef, very capable, but only a single pair of hands having to do everything to run this model.
195
That's why it is really, really slow.
196
While for the iPhone, it has CPUs, GPUs, and NPUs.
197
That's why it's able to process things so much faster.
198
So that explains why it is that things run so slowly on the Pi, but run so quickly on iPhone.
199
But what about image generation?
200
The Pi simply cannot do image generation.
201
And that again is because of the lack of GPUs you see
202
when it comes to image video and music generation it is really processing heavy so
203
if you just only have cpus no matter how hard they
204
work it's just not enough to be able to generate music images
205
and videos so you really got to have some gpus like the iphone to be able to do
206
that we will return to this analogy a little bit later as i explain more devices
207
but for now amazing you now have an understanding of ai
208
hardware yay i'll put on screen now a little pop quiz answer these questions
209
and put them into the comments to make sure
210
that you're paying attention of course what i said about ai
211
hardware is much more simplified than it actually is there's concepts like vram unified memory like
212
so much more which i'm not going to go into too much more detail about in this video
213
because i'm sure this video is already very long
214
but this is like the general introduction
215
that will help you a lot in figuring out what kind of models can run on what kind of devices
216
so as you guys can see from this video i have been very into tinkering
217
and running open source models And the next obvious step is also tinkering and customizing the open source models themselves.
218
For that, Crusoe Intelligence Foundry has been amazing.
219
It primarily gives you two things.
220
Serverless inference to run leading open models without touching any of the underlying GPU infra.
221
And serverless fine -tuning to customize the open models on your own data without having to own or manage any hardware.
222
You can fine -tune a model, deploy it in one click, and start calling it with an API in minutes.
223
Seriously, the first time that I did this, I almost shed a tear.
224
There is no clusters to provision or crazy long setups.
225
I cannot even explain how painful this used to be.
226
So for today, anybody that's building with open models who don't want the infrastructure overhead to eat into actual build time, this is a really clean and easy path to get started.
227
And now when you sign up, you will get $5 of free credit.
228
You can now try out Caruso, link is in the description.
229
Thank you so much, Caruso, for sponsoring this portion of the video.
230
Now, back to the video.
231
Okay, now let's move on to the next category of devices, which is personal computers, such as my MacBook Pro that I'm more using right now.
232
So my MacBook Pro is 32 gigs, but of course there are other machines in this category as well, like my older machine, which is a MacBook Air,
233
and of course, Windows laptops and Linux laptops too.
234
They all belong in these portable, personal computer, personal machines category.
235
So the reason why I got a MacBook Pro with 32 gigs of RAM is
236
because this is the machine that pretty much allows me to run any category of AI models.
237
I can run large language models, coding models, visual language models for visual analysis, image generation, video generation, text -to -speech,
238
speech -to -text, audio generation, voice cloning, and music generation.
239
All of this I can run locally.
240
And not only can I run each of these models locally by itself, I'm also able to use these models in different ways by using it with different types of software.
241
For example, with my Hermes agent, which I use to run many aspects of my life and my work, I can run pretty much any mid -size to large -size local model, like the Quen 3 14B,
242
16B, 32B, some of my go -tos in the Quen family.
243
And I can run the Quen 3 Coder 30B, locally using also an open -source coding harness like OpenCode, and it works pretty good.
244
My favorite for image generation is FluxDev.
245
I'm going to put a summary slide now of all the different types of models
246
that you can run in this personal computer, personal machine category, as well as some ideas of things that you can build with these models.
247
Now, I know what you're thinking already, but Tina, I don't have a 32 gig MacBook Pro.
248
Understandable.
249
It is really expensive.
250
I only got this machine because it is literally my job to be testing out models and things, right?
251
Don't worry, I got you.
252
I'm also gonna put on screen now the models that you can run if you have.
253
8 gigs of ram and 16 gigs of ram these are the general ram sizes of laptops
254
that most people have but if you do have something that's not like 8 gigs
255
or 16 gigs literally you have something smaller bigger something in the middle
256
that is okay as well
257
because i'm also teach you a formula for calculating roughly the size of model
258
that you can run on your machine giving the amount of ram
259
that you have okay ready the equation is
260
that take the total amount of ram that your machine says it has subtract
261
that by 25 of it because this is used up by like other stuff
262
and the rest is the actual usable amount of RAM that you have.
263
Divided by 0 .6 and that equals the amount of parameters that your model can have.
264
For example, my MacBook Pro says it has 32 gigs of RAM.
265
So I subtract 25 % of that, which means I have 24 gigs of usable RAM.
266
Now I do 24 divided by 0 .6 to get 40.
267
So my MacBook Pro can fit a model of up to 40 billion parameters.
268
That is a very rough way of figuring it out.
269
Of course, you can also just ask one of your favorite AI chatbots.
270
Hey, this is my computer
271
and what kind of models can i fit on it you know
272
that works too but in any case i hope
273
that is helpful i want to now move on to the next category of devices home servers the two
274
that i have to demo right now is the mac studio
275
and the amd ryzen ai halo all right the mac studio
276
and the amd ryzen these are examples of the home server class there are a lot of other machines
277
that fit into this category i would say the cheapest entry
278
level here would be a mac mini although those are really hard to get these days.
279
I actually only got the Mac Studio because I couldn't get a Mac Mini.
280
Anyways, at this tier, what is the most attractive and why you would get something like this is for two reasons.
281
The first one is that it is a dedicated always -on machine.
282
So unlike your laptop, which you gotta carry around and close in, stuff like that, and when you close it, your, you know, your models start working in case you were doing something with it.
283
But the home servers, these machines are always on.
284
They are designed to be always on, so they don't close down.
285
You can constantly be doing stuff and running your AM models 24 -7.
286
That's the first attractive part.
287
And the second reason is that generally these home server devices do have more capacity
288
and bandwidth so it can run a bigger models
289
and do it faster let's first talk about the mac studio
290
here it has 64 gigs of ram pop quiz it says
291
it has 64 gigs of ram how much of it is actually usable
292
and what is the largest model in billions of parameters
293
that can fit on my mac studio very paying attention put it into the comments amazing hope you got
294
that my mac studio is where i like to run my local models to use for my local ai agents
295
and also allow other devices remember this device the arduino uno r4
296
that couldn't run anything by itself i also like to be able to connect this with my mac studio
297
so it can use the models
298
that are being run on my mac studio this arduino uno
299
is using the quen 3 .6 35b model on this mac
300
studio in order to display encouraging happy messages write into the comments what this says if you can read it.
301
Yay!
302
That's really cool, right?
303
Really with this Mac Studio and all devices that are bigger and more powerful than this, it's not about unlocking new categories of AI models at this point.
304
It's just about being able to run bigger models, higher quality things to get higher quality responses, and faster.
305
In the case of the Mac Studio, I can run large tier, large language models between 27 to 32 billion parameters, as well as large code models,
306
large image models, and large music generation models.
307
for video generation i can now run mid -tier video generation like the one 2 .2
308
but it is slow it is really slow still i'm going
309
to put a summary slide now with all the models
310
that you can run with a mac studio as well as some ideas for things you can build
311
and let's move on to the amd halo
312
which is 128 gigabytes of advertised ram now with 128 gigabytes of advertised ram Around 96 gigabytes of usable RAM,
313
it is now able to comfortably run extra large models in the 70B range
314
and Frontier models in the 100 to 250B range.
315
We can see that Llama 3 .3 70B is able to run fine
316
and GPT -OSS 120B is also able to run fine.
317
It's also able to run extra large tier of coding models like the DeepSeat Coder V2.
318
Great.
319
So we can see that it can run bigger models now.
320
Makes sense.
321
However, what I find the most useful of having something like this
322
is the ability of having a lot of different models loaded simultaneously
323
and working simultaneously because it has that massive amount of memory, right?
324
So I could be using a coding agent, the large language models, and doing like image video generation all at the same time.
325
I'm going to put on screen now all the models
326
that you can run with a device like the AMD Halo and ideas of what you can build.
327
But I do want to make a caveat here though.
328
This machine, even though it has very large capacity, it actually has pretty small bandwidth, which means that it is slow,
329
especially when it comes to image, video, and music generation.
330
You can do it.
331
It's just going to do it really, really slow, which is why I want to introduce you to the final category that we're going to cover today, which is GPUs.
332
First, let me explain GPUs a little bit more remember the analogy
333
that we had earlier the restaurant kitchen analogy we said
334
that gpus is like having a brigade of line cooks
335
because we have so many of them they're able to work really really quickly
336
and it do compute very fast now this matters the most
337
when it comes to music generation image generation and video generation
338
because to be able to produce these you just need like a lot of processing power
339
so you need a lot of line cooks in the kitchen the bad news is
340
that all the devices that i went through earlier they do of course have gpus
341
which is why they can do things like music generation image generation
342
and video generation but they do it really really slowly
343
because they're not specialized at doing this but the good news is
344
that there is a way to be really good at processing
345
and be able to do really fast and really good image music
346
and video generation and
347
that is by getting more discrete gpus you see a gpu actually isn't just line cooks it's actually a bundle
348
when you get another gpu you get cooks
349
but they also come with their own private prep counters
350
and a very wide conveyor belt the memory pass so
351
when you get more gpus you get more cooks who have their own private counter
352
and their very own very wide conveyor belt the memory pass
353
so they're able to get the ingredients really fast it's basically like a boost for the line cooks
354
so you're able to process things really really quickly cook your models really quickly i hope
355
that analogy makes sense it's getting really late
356
so there are a few ways to get more gpus unfortunately for all the devices
357
that we covered earlier you cannot add more gpus to them just like they're not built
358
that way but if you had a gaming pc for example that would have a GPU.
359
I do not have a gaming PC and I'm not about to go buy one right now because those are expensive.
360
But if you do have one, good news for you.
361
You have a GPU and you can actually add more GPUs as well.
362
So I'm going to cheat a little bit, okay?
363
Because I do want to show you what it's like to run these multi -modality generation models on these specialized GPUs.
364
So I'm actually going to rent an RTX 4090.
365
This is a pretty high -end GPU that you might have in a high -end gaming set.
366
Let's do this quickly because it's costing me by the hour.
367
We're going to log in here and then I'm going to run an image generation model.
368
You can see that it is really, really quickly.
369
And here is a video generation as well.
370
Really, really quick.
371
Now, the downside of this GPU is that it only has 24 gigs of memory.
372
So you can think about it almost like the opposite of the AMD device
373
because the AMD device has a lot of memory, has very big capacity, but low bandwidth while the RTX 490 has smaller capacity, only 24 gigs, but much larger bandwidth.
374
So in the end, you end up being able to generate a lot of these things and run these models, but you can't really fit very large size models on it.
375
All right, I'm going to now put a summary slide for the models
376
that you can run on this device and the things that you can build with it.
377
And that finally leads me to the final boss, the 8X H100 GPU.
378
Now this is top tier, 640 gigs of RAM, massive capacity and massive bandwidth.
379
Now I really gotta move fast on this one
380
because it's costing me so much money every minute but for you guys it's worth it.
381
On here not only can we run ultra large tier large
382
language models up to 700 billion parameter plus ultra large coding
383
models 480 billion parameters plus visual language processing as well and all types of multimodal generation.
384
Specifically let's check out video generation.
385
Using the minimax h3 model we can see that it's able to generate minutes of video and it does it so quickly.
386
This is pretty much what you can run assuming
387
that you're not like a literal model development company or just have like a lot of money.
388
But it really is comparable at this point to the frontier models that you're paying for through cloud APIs.
389
You see everything up to this GPU is kind of just forcing you to choose between like capacity
390
and bandwidth right like the AMD Halo is all about big capacity below bandwidth
391
and the RTX 490 is all about small capacity and large bandwidth
392
but this is when you get both you get very big capacity
393
and very big bandwidth
394
and now for the 8H100 rented I'm gonna put a summary slide now of the models
395
that you can run with it and the things
396
that you can build this is like aspirational class great amazing wow thank you
397
so much for watching until the end of this video i hope this was insightful interesting helpful
398
and it has inspired you to want to build things with
399
local ai as well i'm going to put on screen now
400
a little quiz please answer these questions in the comments below to help you retain all of the information
401
that we have covered today thank you so much and I will see you guys in the next video or live stream.

Những câu đáng luyện lại

Các câu ngắn, trọn ý trong video mà bạn có thể dùng lại khi giao tiếp hằng ngày:

  • We're not even installing it.
  • Don't worry, I got you.
  • Specifically let's check out video generation.

Ngữ pháp trong video

Những cấu trúc người nói dùng nhiều nhất, kèm đúng cụm từ trong video:

Cấu trúcTrong video
Câu bị động be + quá khứ phân từ — nhấn vào việc xảy ra, không phải người làmis sponsored · are called · is just built
Mệnh đề quan hệ who / which + mệnh đề — thêm thông tin về người hoặc vậtscreen, which is · people who work · devices, which is
Thì hiện tại hoàn thành have/has + quá khứ phân từ — việc đã xảy ra nhưng còn liên quan đến hiện tạihave specialized · have seen · have been

Phát âm cần chú ý

Người nói dùng 69 dạng rút gọn, ví dụ I'm, don't, they're. Hãy nói theo dạng ngắn đúng như bạn nghe.

  • Âm “sh” và “zh”: preposition /ˌpɹɛpəˈzɪʃən/, specialize /ˈspɛʃəˌlaɪz/, detection /dɪˈtɛk.ʃən/, aspirational /ˌæspəˈɹeɪʃənəl/, bookshelf /ˈbʊkˌʃɛlf/
  • Từ dài — đặt trọng âm cho đúng: preposition /ˌpɹɛpəˈzɪʃən/, parameter /pəˈɹæm.ə.tɚ/, analogy /əˈnæləd͡ʒi/, ingredient /ɪnˈɡɹiːdi.ənt/, aspirational /ˌæspəˈɹeɪʃənəl/

Những âm người Việt thường gặp khó:

  • Cụm phụ âm cuối — đọc đủ từng âm, đừng nuốt âm cuối: bandwidth /ˈbændwɪdθ/, ingredient /ɪnˈɡɹiːdi.ənt/, subtract /səbˈtɹækt/, downstairs /daʊnˈstɛɹz/, surround /səˈɹaʊnd/
  • Âm /tʃ/, /dʒ/ và /ʒ/ — tiếng Việt không có, đừng đọc thành “ch” hay “gi”: analogy /əˈnæləd͡ʒi/, chop /t͡ʃɑp/, camouflage /ˈkæ.məˌflɑːʒ/, chatbot /ˈtʃætbɑt/, diffusion /dɪˈfju.ʒən/
  • Âm /æ/ — mở miệng rộng hơn âm “e”: bandwidth /ˈbændwɪdθ/, parameter /pəˈɹæm.ə.tɚ/, analogy /əˈnæləd͡ʒi/, subtract /səbˈtɹækt/, webcam /ˈwɛbˌkæm/

Cách luyện với video này

  1. Nghe hết video một lần, chưa cần nói, và ghi lại những từ bạn chưa biết.
  2. Bắt đầu ở tốc độ 0,75×, nói đuổi từng câu, rồi quay lại tốc độ bình thường khi đã quen.
  3. Ghi âm giọng mình rồi so với bản gốc, chú ý các từ như gig, preposition, analogy.

Phương Pháp Shadowing Là Gì?

Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
