piper

A fast, local neural text to speech system. Try out and download speech models from https://rhasspy.github.io/piper-samples. More information: https://github.com/rhasspy/piper.

Output a WAV [f]ile using a text-to-speech [m]odel (assuming a config file at model_path + .json):

echo {{Thing to say}} | piper -m {{path/to/model.onnx}} -f {{outputfile.wav}}

Output a WAV [f]ile using a [m]odel and specifying its JSON [c]onfig file:

echo {{'Thing to say'}} | piper -m {{path/to/model.onnx}} -c {{path/to/model.onnx.json}} -f {{outputfile.wav}}

Select a particular speaker in a voice with multiple speakers by specifying the speaker's ID number:

echo {{'Warum?'}} | piper -m {{de_DE-thorsten_emotional-medium.onnx}} --speaker {{1}} -f {{angry.wav}}

Stream the output to the mpv media player:

echo {{'Hello world'}} | piper -m {{en_GB-northern_english_male-medium.onnx}} --output-raw -f - | mpv -

Speak twice as fast, with huge gaps between sentences:

echo {{'Speaking twice the speed. With added drama!'}} | piper -m {{foo.onnx}} --length_scale {{0.5}} --sentence_silence {{2}} -f {{drama.wav}}
