Lightweight CPU-friendly text-to-speech with voice cloning. No GPU required.
pip install pocket-tts
# or
uv add pocket-tts
# Basic generation (default voice)
pocket-tts generate --text "Hello world"
# Custom voice (local file, URL, or safetensors)
pocket-tts generate --voice ./my_voice.wav
pocket-tts generate --voice "hf://kyutai/tts-voices/alba-mackenna/casual.wav"
pocket-tts generate --voice ./voice.safetensors
# Quality tuning
pocket-tts generate --temperature 0.7 --lsd-decode-steps 3
See docs/generate.md for full CLI reference.
# Start FastAPI server with web UI
pocket-tts serve
# Custom host/port
pocket-tts serve --host localhost --port 8080
See docs/serve.md for server options.
Convert audio files to .safetensors for faster loading:
# Single file
pocket-tts export-voice voice.mp3 voice.safetensors
# Batch conversion
pocket-tts export-voice voices/ embeddings/ --truncate
See docs/export_voice.md for export options.
