Interesting that SoundStorm was trained to produce dialog between two people using transcripts annotated with '|' marking changes in voice. But the exact same '|' characters seem to mostly work in the Bark model out of the box and also produce a dialog?

Maybe a third or a bit more of Bark outputs are a dialog person talking to themselves -- and it often misses a voice change. But the pipe characters do reliably produce audio that sounds like a dialog in the performance style.

Is there some text-audio data somewhere in the training data that uses | for voice changes?

Amusingly, Bark tends to render the SoundStorm prompts sarcastically. Not sure if that's a difference in style in the models, or just Google cherry picking the more straightforward line readings as the featured samples.
