    Gradium drops phonon-31m-en: a 64.5 MB local TTS that runs inside browser tabs

    Gradium just released phonon-31m-en, a lightweight English text-to-speech model built on Pocket TTS and Kyutai's Mimi codec. Weighing just 64.5 MB in 8-bit quantization, it streams natural 24 kHz speech entirely on-device across laptops, smartphones, and web browsers under the Apache 2.0 license. Why it matters: offline, zero-latency voice agents just became dirt cheap to deploy anywhere.

    Kyutai's Pocket TTS runs voice generation on pure CPU

    Kyutai just open-sourced Pocket TTS, a lightweight 100M-parameter text-to-speech model built to run entirely on CPUs without GPUs. It clocks in at roughly 6x real-time on a MacBook Air M4 with a 200ms time-to-first-audio latency, bringing voice cloning and infinite text streaming straight to consumer hardware.
