Hi Dear Customer, We can use below code to read the VAD status.
-------------------------------------------------------------------------------------------
from tuning import Tuning
import usb.core
import usb.util
import time
dev = usb.core.find(idVendor=0x2886, idProduct=0x0018)
#print dev
if dev:
Mic_tuning = Tuning(dev)
print Mic_tuning.is_voice()
while True:
try:
print Mic_tuning.is_voice()
time.sleep(0.001)
except KeyboardInterrupt:
break
-------------------------------------------------------------------------------------------
For the threshold of VAD, we also can use the GAMMAVAD_SR to set.
-------------------------------------------------------------------------------------------
GAMMAVAD_SR float 1000 0 rw Set the threshold for voice activity detection.
[−inf … 60] dB (default: 3.5dB 20log10(1.5))
-------------------------------------------------------------------------------------------
thanks.
