Unable to record speech

[phanikumar1210]

I am newbie to this Google and its API's I was able to decode the sample raw files. But I was unable to use speech recognition from microphone and I am getting the following error on my run.

events.js:160
      throw er; // Unhandled 'error' event
      ^

Error: spawn rec ENOENT
    at exports._errnoException (util.js:1007:11)

    at Function.Module.runMain (module.js:577:11)
    at startup (node.js:160:18)

Could you please let me know what is the exact issue.

We just published new Node.js Google Cloud Speech API samples a few hours ago. Give them a try: https://github.com/GoogleCloudPlatform/nodejs-docs-samples/tree/master/speech

[jmdobry]

Basically:

1. git clone https://github.com/GoogleCloudPlatform/nodejs-docs-samples.git
2. cd nodejs-docs-samples/speech
3. npm install
4. node recognize.js listen - Starts listening to your microphone, and detected speech is printed to your console

I am getting the same error with new code as well. I think there is an issue with microphone recognization do I need to make any changed to the settings to identify or recognize microphone. I am using windows 8.1.

Looking at https://github.com/gillesdemey/node-record-lpcm16 (which is what the microphone recording sample uses), it looks like you need to have SoX installed on your system. For windows, it looks like you have to download a binary

[phanikumar1210]

I have installed it after having a look at the node module requirements. But I was unable to perform recording.

launch brew install sox on OSX fixed it for me

[phanikumar1210]

I am working with windows operating system and I have installed sox on it but I am facing the same error. I have also tried using node-record-lpcm16 module there is a problem with that module itself.

@phanikumar1210 Have you opened an issue on the node-record-lpcm16 repository?

[phanikumar1210]

There is an existing issue on it without response. Do we have any other source which is working on windows. On which platforms is this code got tested. Does this code work on Ubuntu platform.

Did anyone get this working on the Windows OS?

I think i found a fix.
See my comment over at gillesdemey/node-record-lpcm16#8.

@damienromito probably has the right solution if you're on mac (brew install sox)

[northwindapps]

When deploying it to Heroku, what should I do to install sox there?

UPDATE: Seems Heroku doesn't support microphone-input, I try it on GAE.
