[mobileraj]

Is there a concise example where a user from a web page is initiate speech thru their local microphone, which is streamed to Google Speech to Text API and then respond with realtime text transcipt for the user. I saw this site https://www.google.com/intl/en/chrome/demos/speech.html but dont seem to find the source or example code posted any where.

Thanks in advance.

Hi @mobileraj ,

Google doesn’t provide an official browser-to-Speech-to-Text API streaming example out of the box, but you can build it using:

• Web browser side: use WebRTC / Web Audio API to capture the mic stream.

• Backend server: stream audio to Google Speech-to-Text API using a WebSocket or gRPC.

A good starting point:
