我正在使用 Raspberry pi 3B 处理语音识别系统，在运行某些代码时，我遇到了一些问题，如下所示。我从互联网上尝试了这么多东西但是找不到一些具体问题所以请帮我解决下面的错误！

我在 Raspberry pi 中执行以下.py代码时遇到上述错误：

import speech_recognition as sr
import textToVoice as tv

r = sr.Recognizer()

with sr.Microphone(device_index = 0, sample_rate = 44100, chunk_size = 512) as source:
    print('Say Somrthing For Google Search')
    try:
        audio = r.listen(source)
    except exception_on_overflow as e:
        print('prob')
    print('Now, Processing on your request!')

try:
    text =r.recognize_google(audio)
    lang = 'en'
    tv.tts(text, lang)
    print('You Say:\n' + text)

except Exception as e:
    print('problem For Fatchning Page')
    print(e)

[Errno -9998]频道数无效

我改进/清理你的代码：

import speech_recognition as sr
import textToVoice as tv

r = sr.Recognizer()

with sr.Microphone() as source:  # your problem was at this line.
    print('Say Something For Google Search')
    try:
        audio = r.listen(source)
    except Exception as e:
        print(e)
    print('Now, Processing on your request!')

try:
    text =r.recognize_google(audio)
    lang = 'en'
    tv.tts(text, lang)
    print('You Say:\n' + text)

except Exception as e:
    print('problem For Fatchning Page')
    print(e)

您可以按照以下步骤进行安装：

sudo pip install SpeechRecognition

sudo pip install pyaudio

如果您发现错误：

sudo apt-get install python-pyaudio

sudo apt-get install libjack-jackd2-dev portaudio19-dev

然后再说：

sudo pip install pyaudio

如果您发现错误，请尝试以下操作：

sudo pip install --upgrade pyaudio
