Я работаю над системой распознавания голоса с Raspberry pi 3B , и во время выполнения некоторого кода я сталкиваюсь с некоторой проблемой, которая описана ниже.Я перепробовал столько вещей из интернета, но не смог найти какую-то конкретную проблему, поэтому, пожалуйста, помогите мне с ошибкой ниже!

Я сталкиваюсь с ошибкой выше при выполнении кода ниже .py в Raspberry pi : 

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] Неверное количество каналов

Я улучшаю / очищаю ваш код: 

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)

Для установки выполните следующие шаги:

sudo pip install SpeechRecognition

sudo pip install pyaudio

Если вы нашли ошибку: 

sudo apt-get install python-pyaudio

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

Затем еще раз: 

sudo pip install pyaudio

Если вы обнаружили ошибку, попробуйте следующее: 

sudo pip install --upgrade pyaudio
