Successful hotword detection; but later that processing audio gets a error - pyaudio

Question

#Global Declarations
CHUNK_SIZE = 1024
MIN_VOLUME = 500
BUF_MAX_SIZE = 1024 * 10
RECORD_TIME_SECONDS = 7
def wakeword():
agent = snowboydecoder.HotwordDetector("res/bella.pmdl",
sensitivity=0.5)
agent.start(detected_callback=listenIntent, sleep_time=0.03)
agent.terminate()
It makes a successful detection. When it gets into listenIntent function it gives me a error
def listenIntent():
print("Hotword")
stream = pyaudio.PyAudio().open(
format = pyaudio.paInt16,
channels = 1,
rate = 44100,
input = True,
frames_per_buffer = 1024)
while True:
for i in range(0,int(44100/1024*RECORD_TIME_SECONDS)):
data = array('h',stream.read(CHUNK_SIZE))
stream_rec = pyaudio.PyAudio.open(format= pyaudio.paInt16,
channels = 2,
rate = 44100,
input = True,
frames_per_buffer = 1024)
threshold = max(stream_rec)
if threshold >= MIN_VOLUME:
print("Recording....")
frames = []
data_rec = data.read(CHUNK_SIZE)
frames.append(data_rec)
stream.stop_stream()
stream.close()
pyaudio.PyAudio.terminate()
_wavefile = wave.open("temp.wav",'wb')
_wavefile.setnchannels(1)
_wavefile.setsampwidth(pyaudio.PyAudio.get_sample_size(pyaudio.paInt16))
_wavefile.setframerate(44100)
_wavefile.writeframes(b''.join(frames))
_wavefile.close()
processAction()
def processAction():
access_token = ""
client = wit(access_token = access_token)
with open("temp.wav",'rb') as f:
response = client.speech(f, None,{'Content-Type': 'audio/wav',
'encoding':'encode',
'bits':'1024',
'rate':'44100',
'endian': 'big'})
print("Response" + str(response))
if __name__ == "__main__":
wakeword()
process
- First wakeword agent triggers
- Starts audio recording for 7 seconds
- Processes the audio file it wit.ai to understand the intent
As soon as i run the program it does a successful hotword detection but later part fails. i.e recording. I get this error.
