跟读练习: The Three NPI Phases Explained - 通过视频学习英语口语

1
Then you say you start your NPI process
2
and this is comprised of three phases and after
3
that it's really ready for ongoing mass production and ramp up of the volumes, right?
4
Correct.
5
So what are these three phases?
6
So the three phases are engineering validation, design validation, and production validation.
7
Some people, a lot of people are familiar with these terms
8
but they're not familiar with what the actual meaning is and how you qualify from one phase to the next.
9
So a lot of people have misinterpreted this to mean that you've got three chances to build it and get it right.
10
That's not correct.
11
Each phase has different meaning.
12
So the engineering validation you want to prove out from an engineering point of view that your tooling is good, your enclosures are good, your PCBA is good,
13
that your features are all present and that your device is working as intended.
14
At the end of an ADT build you should sit in a room with all of your engineers
15
and all of them can say that their functions have been complete and this product is performing as expected.
16
So the output is not only a prototype that's much closer to what's intended
17
because it is made this time with the same manufacturing process as it is intended, it also comes on the supply chain side with a BOM,
18
so you already started to select the component suppliers, you've been working very closely with obviously also the assembly and testing supplier.
19
On the technical side you've gone into all the details of the design, the mechanical design, engineering design, the firmware design and so on.
20
Is that correct?
21
That's correct, yes.
22
So that EBT part that you've built should be fully representative of your supply chain and your processes.

- 长单词——注意重音位置: validation /ˌvæl.əˈdeɪ.ʃən/, mechanical /məˈkænəkəl/, misinterpret /ˌmɪs.ɪnˈtɜː.pɹɪt/
如何用这段视频练习
- 先完整听一遍视频，不要开口，记下不认识的单词。
- 先用 0.75 倍速逐句跟读，熟练之后再回到正常速度。
- 录下自己的声音并与原声对比，特别注意 validation, intend, supplier 这类单词。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
