Question About the Result of vad_doa.py

Products & Technology ReSpeaker
1

Dear techsupport

    I run the program "vad_doa.py" with the 6 Mic Circular Array Kit for

Raspberry

Pi (Pi3 Model B+). And the attached file is the log file with the result.
The VAD portion

of this seems to work but the value returned by mic.get_direction() has no
consistency,

and it seems to cause the program to hang quite often.

    I also run the mic_array_dfu, and the result is in the file

“dfu_log”. It shows

“Could not find/open device”. Is there something wrong?

Can you provide your professional advice for me ? Thanks for your kindly
support.

Best Regards

Damon Lin

Hi

Damon,


1. For VAD, the accuracy is 30 degree. you can test it by a record audio and play through cellphone at specific direction.

2. For

mic_array_dfu, it is used for respeaker mic array v1.0, it can not used for the 6 Mic Circular Array Kit for Raspberry.



Thanks

Dear Techsupport

    Thanks for your kindly support.

    The file ‘vad_doa_log.txt’ is record without any speaking, and the VAD always print ’1’,

Is the function ‘vad.is_speech’ work normally?

Best Regards

Damon Lin

Hi Damon,


For the DOA, please use this example to read the DOA.

http://wiki.seeedstudio.com/ReSpeaker_6-Mic_Circular_Array_kit_for_Raspberry_Pi/#librespeaker-aduio-process

For DOA without keyword example, I tested it and it will stuck after running a while. But VAD is 0 when there is no noise and 1 when there is noise. I remove from wiki and check with software team.
