Post says most full-duplex voice models build on Moshi and face architectural bottlenecks

According to a post on X by @Neuralwarlock, nearly all current full-duplex speech models iterate on the same Moshi architecture. In that design, each text token is locked one-to-one to an audio frame that is spoken right away, which the author describes as a real bottleneck. The post was a reply to @yiz_be_building's question about why full-duplex models are not used in production, and @jpclap reposted it. The snippet notes that only the opening of the post was read, so the rest of the argument is not covered here.

AI-assisted summary based on the listed source.

@Neuralwarlock argued that nearly all current full-duplex speech models iterate on the same Moshi architecture, where every text token is locked one-to-one to an audio frame that is spoken right away, which he sees as a real bottleneck. He was answering @yiz_be_building's question about why full-duplex models...

Developers building real-time voice assistants may want to understand this design constraint when evaluating full-duplex models for production. Businesses considering conversational voice products could see the production gap as a reason to wait for alternative architectures. Watch for further technical responses or published comparisons that test whether this bottleneck limits real-world performance.
