       | I wish they'd describe the technical details of the differences
       | between this and other TTS they were "inspired by".
       | 
       | So many projects like this, I will just have to assume they are
       | vibe-coded clones to get some publicity unless there's more
       | technical details.

         | Sesame is an impressive real time conversational audio-to-audio
         | model you can talk to on their website [1]. But it's closed
         | source. They released some components, but nothing you could
         | use to duplicate their work.
         | 
         | Sesame is what this team (and lots of teams) want to build. I
         | know another team trying to build a real time local NSFW
         | girlfriend you can talk to. They're convinced they can reach
         | $100M ARR quickly if they crack it and make it customizable.
         | 
         | KyutaiTTS provides a lot of the ingredients for this work, but
         | it isn't conditioned for audio to audio afaik or any of the
         | streaming components.

         | your assumption.

       | Looks very similar to Kyutai's models, given that it uses the
       | same neural audio codec (Mimi) and Depformer module etc.

       | Not sure if it's an artifact of their streaming approach but
       | their intro demo has exclamation marks and question marks and the
       | intonation through the sentence just doesn't fit. It's vocalized
       | regularly with only the last word having that exclamation or
       | question sound. Maybe we need that Spanish upside down question
       | mark at the start to help it.
