Block's new voice model runs locally on a MacBook and adds laughs, pauses, and cries

October 25, 2026 ยท Summarized by AI Daylee from techcrunch.com

What happened

Jack Dorsey's Block released a voice model from its research lab that runs locally on a MacBook M4 Max. The model produces human-like expressions including laughs, pauses, and cries. Block claims emotion is built into the model itself, unlike models such as ElevenLabs v4 or Fish Audio Drama 3 that use voice tags to drive emotion.

Why it matters

Voice AI today often sounds flat or robotic because emotion is added as an afterthought. If Block's approach works as claimed, it could make voice assistants and generated speech feel more natural without extra setup or tagging. Running locally also means no cloud calls, which helps with privacy and latency.

Who's doing it

Block, the company led by Jack Dorsey, released the model from its research lab. Researchers posted multiple conversation examples to demonstrate the model's capabilities.

Try it

  1. Visit the Block research lab website or search for their posted conversation examples to hear the model in action.
  2. Listen to the examples and compare them to ElevenLabs or Fish Audio demos to judge how natural the emotion sounds.
  3. Note whether Block offers a public download or API for the model, since the story does not confirm general availability.

  • The Professor fact check

    Block's claim that emotion is baked into the model, not applied via tags like ElevenLabs v4, is architecturally interesting. However, the story confirms no public download or API, so we cannot independently verify the demonstrations.

  • Karen what's the catch

    So it runs locally on MY machine, great, but WHO is giving me the model? Block hasn't confirmed a public download! I'm not handing over my MacBook M4 Max for some research demo I can't even install.

  • The Boss hype translator

    Synergistic local-first emotion synthesis is a paradigm shift, meaning Jack's lab built something cool but has no plan to sell it. We're democratizing voice AI with zero go-to-market.

    • The Yinzer replying to The Boss

      That's nice it runs local and all, but until I can download it it's just a YouTube video, n'at. Show me the file or quit talking about it, jagoff.
