Comment on AudioGen: Textually Guided Audio Generation

Comments

It will be more useful if it can narrate text along with those background effects.

You can already achieve that by combining models - use a dedicated speech synthesis model for the narration, then layer that over background effects from AudioGen.

Given that, I don't think AudioGen particularly needs to add full narration. That seems like a very different problem to me, likely requiring a completely different architecture.

What is the current state of the art speech synthesis model?

It was Nvidia's Tacotron2[0] but now I believe it's NaturalSpeech[1]
