我正在开发一个使用 Speech_recognition 模块的项目。

    # Importing all the installed packages
    import speech_recognition as sr
    audio = sr.Recognizer
    try:
     
     with sr.Microphone() as source:
    voice = audio.listen(source)
    command = audio.recognize_google(voice)
    print(command)
  finally:
pass

我收到此错误

我尝试了所有可能的解决方案，但我一次又一次地遇到同样的错误，我正在使用 PyCharm 编辑器。

During handling of the above exception, another exception occurred:

except:   command = command.lower()
NameError: name 'command' is not defined

请帮我。谢谢！

在这里，我有我在其中一个代码中使用的语音识别代码片段，我希望它也适用于您的代码：

import speech_recognition as sr

rObject = sr.Recognizer() 
audio = '' 
with sr.Microphone() as source: 
    print("Speak...")   
    audio = rObject.listen(source, phrase_time_limit = 0) 
    print("Stop.")
    try: 
        text = rObject.recognize_google(audio, language ='en-US') 
        print("You : "+ text)  
    except: 
        speak("Could not understand your audio...PLease try again !")

尝试结帐！

有插座也有command = command.lower()
