常用示例
Synthesize speech
echo "Hello world" | piper --model [en_US-lessac-medium] --output_file [output.wav]
List models
piper --list-models
Use specific model
piper -m [model.onnx] -c [model.json] < [input.txt] > [output.wav]
Set speaker
piper --model [model.onnx] --speaker [0] < [input.txt]
Adjust speaking rate
piper --model [model.onnx] --length_scale [1.5] < [input.txt]
JSON input mode
echo '{"text": "Hello"}' | piper --model [model.onnx] --json-input
说明
piper is a fast, local neural text-to-speech system that generates natural-sounding speech from text using ONNX-based voice models. It runs entirely offline after model download, requiring no internet connection or cloud API. Each model is trained for a specific language and voice. Multi-speaker models support selecting different voice variants via speaker ID. The length_scale and noise_scale parameters control speaking rate and variation, allowing fine-tuning of output characteristics. Input is read from stdin and output as WAV audio. JSON input mode enables structured text processing with per-utterance settings. Models are available for many languages through the Piper project's model repository.
