v 7.0.0
Implemented lesson audio generation with AI TTS. Generate high quality lesson audio!
Alert! The RPM/RPD limit of the Google TTS API is strangely low (10/100 each). So, it will fail for a lesson longer than 100 sentences. I recommend that you use openai API until the limit is eased.

generating 38 minutes amount audio takes 3 minutes.
