python - Azure Speech-To-Text 多语音识别
问题描述
我正在尝试使用 Azure 的 SpeechToText 将对话音频文件转录为文本。我使用 SKD 并再次尝试使用 API(按照此说明https://github.com/Azure-Samples/cognitive-services-speech-sdk/blob/master/samples/batch/python/python -client/main.py),但我也想用不同的声音分割结果文本。是否可以?
我知道它在 beta 版的对话服务中可用,但由于我的音频是西班牙语,我无法使用它。是否有按扬声器拆分结果的配置?
这是使用 SDK 的调用:
all_results = []
def speech_recognize_continuous_from_file(file_to_transcript):
"""performs continuous speech recognition with input from an audio file"""
# <SpeechContinuousRecognitionWithFile>
speech_config = speechsdk.SpeechConfig(subscription=speech_key,
region=service_region,
speech_recognition_language='es-ES')
audio_config = speechsdk.audio.AudioConfig(filename=file_to_transcribe)
speech_recognizer = speechsdk.SpeechRecognizer(speech_config=speech_config, audio_config=audio_config)
done = False
def stop_cb(evt):
"""callback that stops continuous recognition upon receiving an event `evt`"""
print('CLOSING on {}'.format(evt))
speech_recognizer.stop_continuous_recognition()
nonlocal done
done = True
# Connect callbacks to the events fired by the speech recognizer
speech_recognizer.recognized.connect(lambda evt: print('RECOGNIZED: {}'.format(evt)))
speech_recognizer.session_started.connect(lambda evt: print('SESSION STARTED: {}'.format(evt)))
speech_recognizer.session_stopped.connect(lambda evt: print('SESSION STOPPED {}'.format(evt)))
speech_recognizer.canceled.connect(lambda evt: print('CANCELED {}'.format(evt)))
# stop continuous recognition on either session stopped or canceled events
speech_recognizer.session_stopped.connect(stop_cb)
speech_recognizer.canceled.connect(stop_cb)
def handle_final_result(evt):
all_results.append(evt.result.text)
speech_recognizer.recognized.connect(handle_final_result)
# Start continuous speech recognition
speech_recognizer.start_continuous_recognition()
while not done:
time.sleep(.5)
# </SpeechContinuousRecognitionWithFile>
