You will need nodejs and npm to run this examples.
To work correctly all scripts should be run from this directory (voicekit-examples/nodejs).
$ npm install
Run basic (non-streaming) speech recognition example:
$ node recognize.js -e MPEG_AUDIO -r 16000 -c 1 ../audio/sample_1.mp3
To disable automatic punctuation and get up to 3 recognition alternatives:
$ node recognize.js -e MPEG_AUDIO -r 16000 -c 1 --no-automatic-punctuation --max-alternatives 3 ../audio/sample_1.mp3
Run streaming speech recognition with interim results and disabled voice activity detection (VAD):
$ node recognize_stream.js -e MPEG_AUDIO -r 16000 -c 1 --interim-results --no-perform-vad ../audio/sample_1.mp3
Specify longer silence timeout for voice activity detection (you will probably need longer audio to actually see the difference):
$ node recognize_stream.js -e MPEG_AUDIO -r 16000 -c 1 --interim-results --silence-duration-threshold 1.2 ../audio/sample_1.mp3
Return just the first recognized utterance and halt (you will probably need longer audio to actually see the difference):
$ node recognize_stream.js -e MPEG_AUDIO -r 16000 -c 1 --interim-results --single-utterance ../audio/sample_1.mp3
To run basic speech synthesis and save result to wav:
$ node synthesize_stream.js -r 48000 -e LINEAR16 "И мысли тоже тяжелые и медлительные, падают неторопливо и редко одна за другой, точно песчинки в разленившихся песочных часах." output_1.wav
You can also specify alternative stress with 0 sign after a vowel:
$ node synthesize_stream.js -r 48000 -e LINEAR16 "За0мок - замо0к." output_2.wav
Feel free to use arabic numerals and named entities:
$ node synthesize_stream.js -r 48000 -e LINEAR16 "Газета Times, 03 января 2009 года - Канцлер на грани ради второго спасения банков." output_3.wav
For now, LINEAR16 does not support samples rates other than 48kHz. Use RAW_OPUS (@discordjs/opus required) to specify different sample rates:
$ node synthesize_stream.js -r 16000 -e RAW_OPUS "Привет, мир." output_4.wav
It is possible to use SSML:
$ node synthesize_stream.js -r 48000 -e LINEAR16 --ssml "<speak><p><s>Оригинальная мысль?</s><s>Нет ничего легче.</s></p><break time='300ms'/><p><s>Библиотеки просто набиты ими.</s></p></speak>" output_5.wav
You can specify voice name:
$ node synthesize_stream.js -r 48000 -e LINEAR16 --voice alyona "Привет! Меня зовут Алёна." output_6.wav
