シャドーイング練習: Introducing GPT-6 Astra for developers - 動画で英語スピーキングを学ぶ
レッスンを作成中...
1
GPT-6 Astra is here.
2
It's our latest frontier model and the best model in the world for tasks where raw intelligence matters.
3
For my own projects, Astra feels like working with an experienced collaborator.
4
I'm able to hand it bigger, less well-defined tasks with minimal handholding.
5
And whether you're coding, writing, designing, or just working on things that require a little bit more intellectual horsepower, you'll find that Astra delivers great results,
6
often on the first attempt.
7
So let's talk about the model's new capabilities, starting with computer use.
8
You might already be familiar with computer use.
9
It's a capability that lets a model use a computer or browser like you or I would.
10
With Astra, the model is more accurate and more efficient when using a computer.
11
It's easiest to show this in the ChatGPT app, but Astra's improved skills are also available in the API.
12
I'm going to have it illustrate where where I'm standing.
13
I'll take a photo, then send it to Codex to paint.
14
Use Krita to paint this picture in the style of Van Gogh and add the Golden Gate Bridge in the background.
15
Astra has to keep track of the picture I asked for while working through the app's controls.
16
It's using screenshots to see what's happening while keeping the app in the background, meaning I can stay focused on other work.
17
The model is able to paint a hopefully recognizable picture far faster and far better than I could have done.
18
The same ability can help with the workflows developers use every day, whether you're filling out forms for an API key or performing QA on a mobile app.
19
When it comes to creativity and knowledge work, we've also seen Astra produce significantly better outputs than previous models.
20
We took several prompts of demos, games, and tools we've built with previous models and rebuilt them at different reasoning levels.
21
Across the board, Astra has more attention to detail, better understanding of the user's prompt, and can build more sophisticated outputs.
22
In particular, it excels at building 3D models.
23
I've seen it make incredible renderings of gardens, shipyards, animals, cityscapes, even Dyson spheres.
24
In my own experience, I've found Astra's outputs, from slideshows to essays, significantly easier to read and work with than other models I've tried.
25
Its personality feels more natural to me, especially in the back and forth when I'm giving it feedback.
26
As you might expect, Astra excels at long-running tasks.
27
And as you give models longer, more involved pieces of work, you need better ways to work with them.
28
That's why we're bringing asynchronous tool calling and steering to the Responses API.
29
First, async tools.
30
With asynchronous tool calling, the model can keep working on other parts of a task while a tool call runs.
31
When the results are available, it can use that information to continue.
32
Steering lets you give the model new context or change its direction while a response is still in progress.
33
If you view steering in codecs, this should feel familiar.
34
Let's go ahead and give the model a task and then change what we're asking for while it's working.
35
You can see it pick up my new instruction and adjust its next steps while the tool it already started continues running.
36
I can change the direction without having to cancel the running tool or start the task over.
37
And I get the final result with the new context incorporated.
38
Astra is now available in ChatGPT, Codex, and the API.
39
Try it on your most challenging tasks and take a close look at the results.
40
Happy building.

shadow speechのステップバイステップガイド
この動画は技術的な用語が多く、発音やイントネーションの練習に最適です。英語スピーキング練習やIELTS スピーキング対策にも役立ちます。
- 動画を1.25倍速で視聴：最初は速さに慣れるため、少し速めの再生速度で全体を理解します。
- キーフレーズをメモ：上記のフレーズや「asynchronous tool calling」などの専門用語をメモし、発音を確認します。
- 一文ずつshadow speech：動画を一時停止しながら、話者のイントネーションやリズムを真似て繰り返します。英語の発音を良くするには、口の形や息の使い方にも注意しましょう。
- 全体をまとめて再生：最後に正常速度で動画を再生し、自分の発音と比較して修正点を見つけます。
動画で英語学習する際は、繰り返し練習することが重要です。この方法で、自然なスピーキング能力が向上します。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
