We just released unmute.sh 🔇🔊 It is a text LLM wrapper, based on in-house streaming ASR, TTS, semantic VAD to reduce latency. ⏱️ Unlike Moshi 🟢, Unmute 🔊 is turn base, but allows customization in two clicks🖱️: voice and prompt! Paper and open source coming soon.

Just back from holidays, so a bit late, to announce MoshiVis, extending Moshi's multimodal capabilities to take in images 📷. Only 200M weights were added to plug a ViT through cross attention with gating 🖼️🔀🎤 Training relies on a mix of text only and text+audio synthetic data (~20k hours) 💽

Even Kavinsky 🎧🪩 can't break Hibiki! Just like Moshi, Hibiki is robust to extreme background conditions 💥🔊.
