node-record-lpcm16 | bit signed-integer linear pulse modulation code

In order to use this library on Electron you have to add extra installation arguments to specifically install for Electron. Electron has generic instructions for using native Node modules.

For gRPC in particular, with the version of Electron you have, you should be able to get it by running

I built a playground to tackle this task. It doesn't use any of the previous plugins (node record 16 / microphone-stream / ...) but sends a 16 bit audio stream to the node server via socket.io.

I'm not 100% certain, but it sounds like there could be multiple explanations:

1. The request is asking for a "single utterance" (StreamingRecognitionConfig)

   This seems unusual because the default appears to be false. However it can't hurt to be explicit in the request (const request = { singleUtterance: false, config: {...} })

2. You're running into the client-defined timeout (createRecognizeStream).

   This also seems a bit strange because I'm guessing you're not sitting there talking for 60 seconds straight and then stopping after such a long time.

3. Your mic is closing the stream which gets propagated back to the Speech client.

   This seems a bit more plausible, but I'm not 100% confident.

If you can record what you're saying into the microphone and reproduce this problem with a file sent via the createRecognizeStream method (rather than a live audio stream), that eliminates the last item, and would make it easier to diagnose.
