Kokoro TTS
Lightweight and expressive TTS model with 82M parameters for fast local inference.
About
At just 82 million parameters, Kokoro is an open weight text-to-speech model that produces speech quality comparable to much larger systems while running faster and at lower cost. The accompanying Python library installs via pip and handles inference, including streaming audio output at a 24 kHz sample rate. Kokoro speaks eight languages, American and British English, Spanish, French, Hindi, Italian, Japanese, Brazilian Portuguese, and Mandarin Chinese, with multiple voices available. It depends on espeak-ng for phonemization and runs on CPU, CUDA GPUs, or Apple Silicon, making real time synthesis feasible on consumer hardware without a dedicated graphics card. Because the weights are Apache licensed, commercial deployment is permitted, and the model shows up in production voice features as well as hobby projects where cloud TTS would be too slow or too expensive. Developers building reading apps, voice assistants, and audio pipelines are typical users.
Should you use Kokoro TTS?
Pick it when
Pick Kokoro when you want natural speech in real time on CPU or modest hardware, in any of its eight languages, under Apache-2.0 weights, for reading apps, assistants, or batch audio pipelines where cloud TTS costs too much.
Look elsewhere when
Skip it if you need to clone a specific voice or steer emotion; Chatterbox or F5-TTS handle cloning. Languages outside its eight, such as German or Korean, need CosyVoice or Fish Speech instead.
Alternatives to Kokoro TTS
- Piper TTS
Runs on Raspberry Pi class boards with more languages and documented custom voice training, where Kokoro's library covers inference only.
- KittenTTS
Much smaller at 25 to 80 MB for tight edge devices, but English only with eight voices and a preview-stage API.
- MeloTTS
MIT licensed CPU real-time synthesis with Korean, several English accents, and training docs for custom voices, but fewer languages overall.
- Chatterbox TTS
Adds zero-shot cloning and emotion control from a reference clip, but its main models want a GPU with about 4 GB; only the English Nano variant targets CPU.

Decent tool but just doesn't have the best sounding voices
