Recognizing issue with Ubuntu 14.04 via microphone

i am having the same problem...did you find a fix?

I'm afraid I've never run into this issue before. Are you by chance using a virtual machine?

If so, I can't really help you other than to suggest you don't do that or that you pipe the output into a file first.

Nope, I ran it on my real linux workstation than a virtual machine. And I think my microphone input is OK since I could get sound recorded via alsa- arecord. 👍 :)
Is there any more method could be check of this issue? I think I have proves that the issue occurs during calling pyaudio.PyAudio()

 def __init__(self, dejavu):
     super(MicrophoneRecognizer, self).__init__(dejavu)
     # Add logging by me
     print "logged here"
     self.audio = pyaudio.PyAudio()

     self.stream = None
     self.data = []
     self.channels = MicrophoneRecognizer.default_channels
     self.chunksize = MicrophoneRecognizer.default_chunksize
     self.samplerate = MicrophoneRecognizer.default_samplerate
     self.recorded = False

A pyaudio issue could be a couple of things:

• check you have ffmpeg installed correctly
• make sure proper codecs are installed

There's of course a host of other issues that it could be, but those are my only experience in troubleshooting pyaudio.

At this point, probably asking around is a good idea. Stack Overflow is always a good resource:

• [http://stackoverflow.com/questions/7088672/pyaudio-working-but-spits-out-error-messages-each-time](PyAudio working, but spits out error messages each time)

Further, make sure you aren't doing anything silly when setting the input and output: https://github.com/bastibe/PyAudio/issues/3.

Thank you pal, I will have more try and let you updated.
I think alsa record works for me, so I think I am not that silly. 😄

Best of luck. If you find a fix, do post here and others may benefit.

Hello,
I have the same problem.
Did someone find a solution ?
There is the details :

• This problem occurs on my 2 OS on the same computer : Ubuntu 14.04 and Kali Linux
• The sound works properly with YouTube
• Micro is activated and works in the parameters
• The error message is this one :

Same problem. Except I'm on Linux Mint.

I do have a setup where I pipe my default speaker into my mic. Maybe I should disable it..?

P.S.: if I set the recording seconds to more than 5 I completely freeze my computer. Maybe it has something to do with memory usage? I do notice that I don't get the same error when running pyaudio.PyAudio() on python3. I'm trying to see if dejavu can be ported to python3 easily.
