【问题描述】：

我一直在尝试使用 Azure 认知服务的 SpeechSDK 转录 (.ogg) 文件。但我不能让它工作。以下是我的代码：

import azure.cognitiveservices.speech as speechsdk
import time

speech_key, service_region = "my-subscription", "eastus"
speech_config = speechsdk.SpeechConfig(subscription=speech_key, region=service_region)
speech_config.speech_recognition_language="es-ES"
# audio_filename = "AudioTest.wav"
audio_filename = "AudioFile.ogg"

def speech_recognize_continuous_from_file():
    """performs continuous speech recognition with input from an audio file"""
    # <SpeechContinuousRecognitionWithFile>
    audio_config = speechsdk.audio.AudioConfig(filename=audio_filename)
    speech_recognizer = speechsdk.SpeechRecognizer(speech_config=speech_config, audio_config=audio_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

    # Connect callbacks to the events fired by the speech recognizer
    # speech_recognizer.recognizing.connect(lambda evt: print('RECOGNIZING: {}'.format(evt)))
    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)

    # Start continuous speech recognition
    speech_recognizer.start_continuous_recognition()
    while not done:
        time.sleep(.5)

    speech_recognizer.stop_continuous_recognition()
    # </SpeechContinuousRecognitionWithFile>

if __name__ == "__main__":
    speech_recognize_continuous_from_file()

问题是当我尝试使用 (.wav) 文件时，它运行良好，但是当我使用 .ogg 文件尝试时，我得到了以下错误记录

目前在 SpeechSDK 中，我们不支持 Python 语言的压缩输入。我们只为 C#、Java、C++ 和 ObjectiveC 提供它。

计划支持 Python 语言的压缩输入。请订阅https://docs.microsoft.com/en-us/azure/cognitive-services/speech-service/releasenotes 以获取下一个版本。
