Azure Speech to Text 麦克风不停止连续录音

Question

I am using Azure Speech to text for transcribing audio thru mic/audio files.

def speech_continuous_recognize_from_mic():
"""performs one-shot speech recognition from the default microphone"""
# <SpeechRecognitionWithMicrophone>
speech_config = speechsdk.SpeechConfig(subscription=configuration["speech_api"]["speech_key"], region=configuration["speech_api"]["service_region"])
# Creates a speech recognizer using microphone as audio input.
# The default language is "en-us".
speech_recognizer = speechsdk.SpeechRecognizer(speech_config=speech_config)

done = False

def stop_cb(evt):
    """callback that signals to stop continuous recognition upon receiving an event `evt`"""
    print('CLOSING on {}'.format(evt))
    nonlocal done
    done = True

all_results = []
def handle_final_result(evt):
    all_results.append(evt.result.text)

speech_recognizer.recognized.connect(handle_final_result)        

speech_recognizer.session_started.connect(lambda evt: print('\nSESSION STARTED: {}'.format(evt)))
speech_recognizer.session_stopped.connect(lambda evt: print('\nSESSION STOPPED {}'.format(evt)))

speech_recognizer.session_stopped.connect(stop_cb)
speech_recognizer.canceled.connect(stop_cb)

# Start continuous speech recognition
**speech_recognizer.start_continuous_recognition()
while not done:
    time.sleep(1)
print ("####################################################################################")
speech_recognizer.stop_continuous_recognition()
speech_recognizer.session_started.disconnect_all()
speech_recognizer.recognized.disconnect_all()
speech_recognizer.session_stopped.disconnect_all()**

stop_continuous_session is not working. Mic is continuously running in the back-end even after force stopping the script

Answer 1

The problem was caused by infinite loop of the while not done code. The code while not done is always true, so it's going to go on forever. The stop code will never be executed.
