Hi,

Is audio input with USB microphone supported? I get error below

SEVERE microphone Can't open microphone line with format PCM_SIGNED 16000.0 Hz, 16 bit, mono, 2 bytes/frame, big-endian not supported.
in edu.cmu.sphinx.frontend.util.Microphone:open-microphone
Cannot start microphone.

Is this a known limitation or do I need to configure something? I am testing with Sphinx4 and trying to run the demo examples.

Thanks & Regards
Srini

  Thanks, this works now. It was more an issue with changing the default audio device

  Verify that your USB device is capable of recording at 16 kHz (i.e. using Sound Recorder or similar program).
