python - 语音SDK拖拽错误: Exception with an error code: 0xe (SPXERR_MIC_NOT_AVAILABLE)

Question

我有一个Python小脚本:

def listen(language):
speech_config.speech_recognition_language=language
audio_config = speechsdk.audio.AudioConfig(use_default_microphone=True)
speech_recognizer = speechsdk.SpeechRecognizer(speech_config=speech_config, audio_config=audio_config)
print("Speak into your microphone.")
speech_recognition_result = speech_recognizer.recognize_once_async().get()
if speech_recognition_result.reason == speechsdk.ResultReason.RecognizedSpeech:
    print("Recognized: {}".format(speech_recognition_result.text))
    return speech_recognition_result.text

此代码源自此处的快速入门 SpeechSDK 教程:https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/get-started-speech-to-text?tabs=linux%2Cterminal&pivots=programming-language-python

它在我的 MacOS Ventura 13.0 检测语音下完美运行。然而，当我在运行 Ubuntu 22.10 的 Linux 机器上使用完全相同的硬件进行音频检测时尝试它，它会抛出以下错误:

Exception with an error code: 0xe (SPXERR_MIC_NOT_AVAILABLE)

我尝试使用 device_name= "hw:CARD=U0x4b40x306,DEV=0 更改麦克风，但这也不起作用。此错误的大多数解决方案都没有提及我的操作系统组合和语言，因此并不真正适用。

Answer 1

我在我的环境中进行了尝试并得到了以下结果:

最初，当我在 Linux 机器上运行 python 脚本时，我遇到了同样的错误。

packages/azure/cognitiveservices/speech/libMicrosoft.CognitiveServices.Speech.core.so(recognizer_create_speech_recognizer_from_config+0xf2)[0x7fd4507d121b] [CALL STACK END]Exception with an error code: 0xe (SPXERR_MIC_NOT_AVAILABLE)

出现上述错误的原因是麦克风无法识别或语音识别系统未检测到。

在Linux中使用arecord -l检查您可以检查您正在使用的声卡。

在我的环境中，我在 Linux 计算机中安装了 pulseaudio，它对我有用。

命令:

sudo apt-get install alsa-base pulseaudio

控制台:

安装pulseaudio后，现在我在我的环境中尝试使用相同的python脚本，它运行得很好。

代码:

import os
import azure.cognitiveservices.speech as speechsdk

def recognize_from_microphone():
    # This example requires environment variables named "SPEECH_KEY" and "SPEECH_REGION"
    speech_config = speechsdk.SpeechConfig(subscription=os.environ.get('SPEECH_KEY'), region=os.environ.get('SPEECH_REGION'))
    speech_config.speech_recognition_language="en-US"

    audio_config = speechsdk.audio.AudioConfig(use_default_microphone=True)
    speech_recognizer = speechsdk.SpeechRecognizer(speech_config=speech_config, audio_config=audio_config)

    print("Speak into your microphone.")
    speech_recognition_result = speech_recognizer.recognize_once_async().get()

    if speech_recognition_result.reason == speechsdk.ResultReason.RecognizedSpeech:
        print("Recognized: {}".format(speech_recognition_result.text))
    elif speech_recognition_result.reason == speechsdk.ResultReason.NoMatch:
        print("No speech could be recognized: {}".format(speech_recognition_result.no_match_details))
    elif speech_recognition_result.reason == speechsdk.ResultReason.Canceled:
        cancellation_details = speech_recognition_result.cancellation_details
        print("Speech Recognition canceled: {}".format(cancellation_details.reason))
        if cancellation_details.reason == speechsdk.CancellationReason.Error:
            print("Error details: {}".format(cancellation_details.error_details))
            print("Did you set the speech resource key and region values?")

recognize_from_microphone()

输出:
