Run mic_vad_streaming.py got error #157
Comments
I get a delay of about 1 second before the recognition starts on a Raspberry Pi 4. Can you try with longer sentences? It looks like the recognition is being triggered (as evidenced by the 'Recognized: ' messages), but returning empty. As an example, I said "testing" 4 times, and it missed the first one:

I think probably it is because I forgot to appoint Device -d.
For my device info like
$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 2: Device [USB PnP Sound Device], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
Tried : python mic_vad_streaming.py -m ../../deepspeech-0.9.3-models.tflite -s ../../deepspeech-0.9.3-models.scorer -d hw:2,0
Does not work.
Can I ask how should I specify the device?
Thanks.
