Kokoro-82M

Kokoro is an open-weight text-to-speech model published by hexgrad on Hugging Face. The upstream card presents it as an 82M-parameter model focused on lightweight, fast, cost-efficient speech generation while still being practical for local and production use.

LA Studio installs Kokoro as a virtual model under hexgrad/Kokoro-82M. The downloadable GGUF artifacts are hosted in conversion repositories:

  • cstr/kokoro-82m-GGUF for the Kokoro backbone GGUF.
  • cstr/kokoro-voices-GGUF for preset speaker voice packs.

Training Notes

The upstream card states that Kokoro was trained on permissive or non-copyrighted audio data with IPA phoneme labels. It lists public-domain audio, permissively licensed audio, and synthetic audio generated by closed-source TTS models as examples of training data sources. The card estimates the total training set at a few hundred hours and reports roughly 1000 A100 80GB GPU-hours across v0.19 and v1.0.

LA Studio Notes

Kokoro in LA Studio is a preset-voice TTS workflow. It needs one backbone model file and one installed voice pack:

  • Default backbone: kokoro-82m-f16.gguf
  • Default voice pack: kokoro-voice-af_heart.gguf

The CrispASR Kokoro runtime depends on espeak-ng for phonemizer support. Kokoro voice cloning from reference audio is not enabled in LA Studio; use the packaged voice GGUF files instead.
