Due to delay patterns, the first chunk is smaller than other chunks

This is inefficient. Only process newly generate tokens.

I noticed some artifacts when passing only the new tokens to the vocoder.

Okay can you fix the delay pattern problem?

This PR introduces the
generate_streamingfunction, which enables streaming audio generation. As soon as audio tokens are generated by the model, the vocoder is run on the entire sequence (using the full sentence as context for best quality), and only the newly generated audio chunk is yielded. The implementation closely mirrors the existinggeneratefunction, but is kept as a separate function (without extracting shared logic) to make the review process easier.Hopefully adding support for #11, #93, #237, making it usable in conversational use cases #181 and accelerating ttfb #153.
