Security handshake failed and speech recognition stops working

Description I encountered this random bug on the smart mirror project, but it seems to come from sonus. When I try the sonus test command (see below)

case 1 : I say the hotword sonus detects it, I wait a while and sometimes if I say nothing I have an handshake error.

case 2 : I say the hotword sonus detects it, I wait a while and I say “hello” or something and then I have an handshake error.

case 3 : I say the hotword sonus detects it, I speak, everthing is going well, I wait a while and I say the hotword then I have an handshake error.

After that it can detect the hotword but it doesn’t detect the speech anymore. Everytime I have at least 3 handshake errors

Unfortunalty it s not easy to reproduce, even if it occurs very often.

How to reproduce

pi@raspberrypi:~/smart-mirror $ npm run sonus

> smart-mirror@0.0.7 sonus /home/pi/smart-mirror
> node sonus.js

Configuration

pi@raspberrypi:~/smart-mirror $ ulimit -n
65536
pi@raspberrypi:~/smart-mirror $  node -v
v6.9.2
pi@raspberrypi:~/smart-mirror $ npm -v
3.10.9

Comments I have this error on the smart-mirror master branch and on the dev branch too I make sure to clean up everything with “git clean -xdf -e config.js” and “npm install” each time

Ideas After some googling, some grpc users seems to have the same issues and it looks related to a connection limit but I only have the smart-mirror running … so it’s weird https://github.com/grpc/grpc/issues/7985

Thanks in advance for your help !

This is an issue with the google speech library, more specifically with the way that grpc handles ongoing connections: GoogleCloudPlatform/google-cloud-node#1905

Seems like the workaround is to extend the time allowed when trying to reestablish a connection. This is something that doesn’t require the modification of sonus to fix!

I’m taking a bit of a guess here because I only glanced at the code, but if you construct your speech object like this before you pass it to Sonus it might fix your issue:

const speech = require('@google-cloud/speech')({
  projectId: 'streaming-speech-sample',
  keyFilename: ROOT_DIR + 'keyfile.json',
  "grpc.initial_reconnect_backoff_ms": 10000
})

I believe this issue is now resolved. If it isn’t I can reopen 😃
