Speech API with browser data

[john.sco...@gmail.com]

I'm trying to use the Google Speech API Streaming recognition using browser mic data but im receiving "audio_content too long" response.

I'm sending the data to server like this with WebSockets:

var left = e.inputBuffer.getChannelData(0);
converted = convertFloat32ToInt16(left)
ws.send(converted);

Previously i sent the sample_rate.

And in the server (Python - Tornado):

encoding='LINEAR16'

yield cloud_speech.StreamingRecognizeRequest(audio_content=data)

data is websocket on_message received data.

Error:

E0907 11:06:54.917320718   14891 chttp2_transport.c:1810]    close_transport: {"created":"@1473246414.916153833","description":"Secure read failed","file":"src/core/lib/security/transport/secure_endpoint.c","file_line":157,"referenced_errors":[{"created":"@1483156814.912117880","description":"FD shutdown","file":"src/core/lib/iomgr/ev_poll_posix.c","file_line":427}]}
Server error: Audio data is being streamed too fast. Please stream audio data approximately at real time.

Thank you very much.

Where does gRPC fit in?   You may need to forward this to a different mailing list.

For Google service-specific issues, please start a question on Stack Overflow. In this case it seems you should tag it with google-speech-api.
