Kokoro is the current open-TTS darling: an 82-million-parameter model small enough to run on modest hardware while sounding surprisingly natural. Crucially it is Apache-2.0, so unlike some open voice models you can use it commercially without a lawyer.

If you want local speech synthesis with no license landmines, start here.

The good

  • Only ~350MB, runs almost anywhere
  • Apache-2.0, the most permissive license here (commercial OK)
  • Punches well above its parameter count

The catch

  • Fewer voices than the big models
  • Newer, smaller ecosystem
  • Not a cloning tool

Pricing

Free and open source.

Alternatives to consider

  • Piper Fast, lightweight neural text-to-speech that runs offline.
  • OpenAI Whisper The open reference model for speech-to-text.
