Voice: allow to respond chat contents with voice for a true conversation

Now I want to hear Copilot respond. It is a nice pair, I talk and I hear the response back. Ideally there is some easy toggle to mute Copilot.

Preview Give feedback

1. Explore UI of others (Bing, OpenAI)
2. Auto synthesise when voice was used by changing mic icon to speaker icon
3. Have action per chat block to synthesize
4. Explore SML: can it be used to control playback speed or skip over code?

Yes, I love the idea and I think with the SDK we have everything we need for it.

I love how Bing does this, when an answer is there you can have it read out with voice but also have a way to stop that:

upvoting since the new "Hey Code" feature is out it would be amazing

I've been looking for this feature since Chat was announced!

Would be a great way to rubber duck and make chat much more helpful in complex projects where it doesn't do as well providing code directly.

A first version is in insiders:

• chat responses have a 🔈 icon to start text-to-speech
• text-to-speech starts automatically for when voice is used as input to chats
• there is a new setting accessibility.voice.autoSynthesize that controls that behaviour
• we support all voice languages that we support in accessibility.voice.speechLanguage
