dictate.js
dictate.js is a small Javascript library for browser-based real-time speech recognition. It uses Recorderjs for audio capture, and a WebSocket connection to the Kaldi GStreamer server for speech recognition.
API
The API is modeled after Android's SpeechRecognizer. See the source code of lib/dictate.js and the usage in demos/demo.js.
Running the demos
The demos connect to the public services running on wss://bark.phon.ioc.ee
that offer Estonian and English speech recognition.
The demos are available here. (Note that in order to use a wss-service the HTML-pages must be loaded over https.)
To run the demos on localhost, start a local HTTP server, e.g.:
python3 -m http.server 8081
and then open e.g. http://localhost:8081/demos/mob.html.
