Add Text to Speech with optional captions.

Can use this API

https://elevenlabs.io/docs/api-reference/text-to-speech/convert-with-timestamps
It generates Speech from text with time codes. People can use their own API key like it was mentioned already in other feedbacks.

There should be a checkbox on the side panel whether to show captions or not and the option to choose style - you already have this functionality.

Here is an example of what I vibe coded yesterday for myself :D
