- Clone the repository:
git clone https://github.com/nazdridoy/kokoro-tts.git
cd kokoro-tts- Install required packages:
pip install -r requirements.txtor
uv syncNote: You can also use uv as a faster alternative to pip for package installation. (This is a uv project)
- Download the required model files:
# Download either voices.json or voices.bin (bin is preferred)
wget https://github.com/thewh1teagle/kokoro-onnx/releases/download/model-files/voices.bin
# or
wget https://github.com/thewh1teagle/kokoro-onnx/releases/download/model-files/voices.json
# Download the model
wget https://github.com/thewh1teagle/kokoro-onnx/releases/download/model-files/kokoro-v0_19.onnxNote: The script will automatically use voices.bin if present, falling back to voices.json if bin is not available.
Basic usage:
./kokoro-tts <input_text_file> [<output_audio_file>] [options]-h, --help: Show help message--help-languages: List supported languages--help-voices: List available voices--merge-chunks: Merge existing chunks into chapter files
--stream: Stream audio instead of saving to file--speed <float>: Set speech speed (default: 1.0)--lang <str>: Set language (default: en-us)--voice <str>: Set voice or blend voices (default: interactive selection)- Single voice: Use voice name (e.g., "af_sarah")
- Blended voices: Use "voice1:weight,voice2:weight" format
--split-output <dir>: Save each chunk as separate file in directory--format <str>: Audio format: wav or mp3 (default: wav)--debug: Show detailed debug information during processing
.txt: Text file input.epub: EPUB book input (will process chapters)
# Basic usage with output file
kokoro-tts input.txt output.wav --speed 1.2 --lang en-us --voice af_sarah
# Read from standard input (stdin)
echo "Hello World" | kokoro-tts /dev/stdin --stream
cat input.txt | kokoro-tts /dev/stdin output.wav
# Use voice blending (60-40 mix)
kokoro-tts input.txt output.wav --voice "af_sarah:60,am_adam:40"
# Use equal voice blend (50-50)
kokoro-tts input.txt --stream --voice "am_adam,af_sarah"
# Process EPUB and split into chunks
kokoro-tts input.epub --split-output ./chunks/ --format mp3
# Stream audio directly
kokoro-tts input.txt --stream --speed 0.8
# Merge existing chunks
kokoro-tts --merge-chunks --split-output ./chunks/ --format wav
# Process EPUB with detailed debug output
kokoro-tts input.epub --split-output ./chunks/ --debug
# List available voices
kokoro-tts --help-voices
# List supported languages
