FacePlex, described in a new preprint, collapses both into a single streaming pipeline. At each step, the system produces speech tokens and facial motion tokens together. Two mechanisms do the heavy lifting: Rolling Flow Matching, which commits new motion frames continuously during streaming, and Rolling Cross-Attention, which lets the audio queue and motion queue inform each other as generation proceeds.\n\nThe gap FacePlex targets is real. Conversational avatars that can only lip-sync to pre-generated audio will always lag — the face responds to the voice instead of moving with it. Genuine joint generation is a prerequisite for avatars that feel like actual conversation partners rather than dubbed video. The researchers back their claims with ablation studies and a user study showing better lip-sync quality and motion fidelity than audio-driven baselines.\n\nAvatar research has accelerated sharply as video-call fatigue and virtual-presence tools push demand, but most commercial products still bolt animation onto finished audio. FacePlex is a preprint, not a product — and turning a streaming research framework into something robust enough for real calls is a long road from an arXiv submission.","[\"avatars\",\"speech-synthesis\",\"facial-animation\",\"ai\"]","2026-06-30T04:00:00.000Z","2026-06-30T06:52:31.789Z","2026-06-30T06:52:41.837Z","published",null,[],"https:\u002F\u002Fcdn.xyz.onl\u002Farticle-images\u002Ffaceplex-makes-avatars-talk-and-move-at-the-same-time.webp","ai",[27,28,29,25],"avatars","speech-synthesis","facial-animation",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2606.30145",0,{"sections":36},[37,41,46,51,56,61,66,71,76,81,86,90,95,100],{"name":38,"slug":25,"count":39,"latest_published_at":40},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":42,"slug":43,"count":44,"latest_published_at":45},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":47,"slug":48,"count":49,"latest_published_at":50},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Dev Tools","dev-tools",59,"2026-07-07T04:00:00.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":87,"slug":88,"count":84,"latest_published_at":89},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
