Snowboy listening but not responding (pyaudio)


#1

Hey!

so in my previos post here:

i figured out i can use arecord fine with s however since google assistant relies on pyaudio that won’t work. after some tinkering i got the pyaudio version of snowbiy to listen but it never responds when the wakeword is said

I’ve confirmed with the
rec
command works and the pyaudio_test.py shown here:


and i get perfect audio

however when i run the pyaudio_test.py this is the output:

 done recording

my demo.py is this:

import snowboydecoder
import sys
import signal
interrupted = False
def signal_handler(signal, frame):

global interrupted

interrupted = True

def interrupt_callback():
global interrupted
return interrupted

if len(sys.argv) == 1:
print("Error: need to specify model name")
print("Usage: python demo.py your.model")
sys.exit(-1)

model = sys.argv[1]

# capture SIGINT signal, e.g., Ctrl+C
signal.signal(signal.SIGINT, signal_handler)

detector = snowboydecoder.HotwordDetector(model, sensitivity=1.0)
print('Listening... Press Ctrl+C to exit')

# main loop
detector.start(detected_callback=snowboydecoder.play_audio_file,
   interrupt_check=interrupt_callback,
   sleep_time=0.03)

detector.terminate()

and my decoder is as shown:

any assitance would be appricated!
