Voice demos are easy to fake. Give a model a clean recording, let it read a theatrical sentence, and the result can sound impressive enough for a launch video. That is not the hard part. The hard part is making speech generation behave like an actual product: multilingual, low-latency, emotionally credible, speaker-consistent, and not outrageously expensive to serve. ...

In text chat, a delay can be tolerated because the medium already feels asynchronous. In speech, delay feels personal. The room has a rhythm, and the machine has missed the beat. ...
