Question

import SpeechRecognition as sp

def takeCommand():
    r = sp.Recognizer()
    with sp.Microphone() as source:
        print("Listening....")
        r.pause_threshold = 1
        audio = r.listen(source)
    try:
        print("Recognising...")
        query = r.recognize_google(audio,language="en-in")
        print(query)
    except Exception as e:
        print(e)
        speak("say that again please")
        return None

    return query
takeCommand()'''

这将返回错误，例如

我安装了正确的lib，还尝试了解pyaudio等内容一切都可以摆脱，昨天我用pysttx3遇到了同样的事情，但是通过重新启动笔记本电脑解决了这个问题，但这不起作用。

您的代码应如下所示：

import speechRecognition as sr

def takeCommand():
    r = sr.Recognizer()
    with sr.Microphone() as source:
       print("Listening...")
       r.pause_threshold = 1
       audio = r.listen(source)
    try:
       print("Recognizing...")    
       query = r.recognize_google(audio, language='en-in') #Using google for voice recognition.
       print(f"User said: {query}\n")  #User query will be printed.

    except Exception as e:
       # print(e)    
       print("Say that again please...")   #Say that again will be printed in case of improper voice 
       return "None" #None string will be returned
    return query

首先，通过在终端中输入这个来导入库-

pip install speechRecognition
