About Kokoro

Kokoro is an 82 million parameter text-to-speech foundation model that delivers expressive, natural voice generation with a tiny computational footprint. While traditional neural voice models require massive GPU clusters or costly proprietary API subscriptions, Kokoro synthesizes human-grade audio faster than real time on standard consumer CPUs and edge devices.

Developed by Hexgrad and released under the Apache 2.0 license, Kokoro has become the community standard for voice-enabled AI agents, audiobooks, and interactive voice assistants. It supports multiple voice accents, natural phrasing, and phoneme-level prosody tuning without requiring cloud connectivity.

  • Lightweight 82M parameter architecture runs faster than real time even on basic CPU hardware
  • Remarkably expressive and natural speech prosody comparable to proprietary voice APIs
  • Permissive Apache 2.0 open-source license with zero per-minute synthesis fees
  • Voice cloning requires fine-tuning rather than instant zero-shot audio prompt matching
  • Primary model releases focus predominantly on English accents, with community multilingual expansions ongoing
