npm install coquisttjs

🛠 Usage examples and tests

Some usage examples and tests. Examples include:

• Simple sentence-based speech-to-text
• coquihttp A simple Speech-to-text HTTP Server
• coquihttp as RHASSPY speech-to-text remote HTTP Server
• SocketIO server pseudocode

🎁 Bonus tracks

• audioutils.js fast transcoding to PCM, using ffmpeg process (install ffmpeg before).

🧶 Status

• The project is in a very draft stage.
• Current Coqui STT npm package solve the DeepSpeech issue. In facts current npm package deepspeech cause a crash using node version 16.0.0. BTW I had success using DeeSpeech npm package with Node version 14.16.1. See my project DeepSpeechJs.
• Complete the high-level API interface. E.g. including metadata as parameters
