【问题描述】：

我正在尝试在一个学校项目中用 python 实现语音识别和响应。无法弄清楚我的代码有什么问题：

代码：（导入speech_recognition as sr）

def takeCommand():
    # It takes microphones recognition from the user and returns String output
    r = sr.Recognizer()
    with sr.Microphone() as source:
        print("Listening...")
        r.pause_threshold = 0.8
        audio = r.listen(source)

    try:
        print("Recognizing...")
        query = r.recognize_google(audio,language='en-in')
        print(f"User said:{query}\n")

    except Exception as e:
        # print(e)
        print("Say that again please")
        return "None"
    return query

print('Listening...') 语句后停止响应。

回溯（在键盘中断时）：

Listening...
Traceback (most recent call last):
  File "c:/Users/Yash Khandelwal/Desktop/Python_Files/Jarvis/Jarvis_Project.py", line 51, in <module>
    takeCommand()
  File "c:/Users/Yash Khandelwal/Desktop/Python_Files/Jarvis/Jarvis_Project.py", line 36, in takeCommand
    audio = r.listen(source)
  File "C:\Users\New User\AppData\Local\Programs\Python\Python37\lib\site-packages\speech_recognition\__init__.py", line 652, in listen    
    buffer = source.stream.read(source.CHUNK)
  File "C:\Users\New User\AppData\Local\Programs\Python\Python37\lib\site-packages\speech_recognition\__init__.py", line 161, in read      
    return self.pyaudio_stream.read(size, exception_on_overflow=False)
  File "C:\Users\New User\AppData\Local\Programs\Python\Python37\lib\site-packages\pyaudio.py", line 608, in read
    return pa.read_stream(self._stream, num_frames, exception_on_overflow)
KeyboardInterrupt

这很容易解决吗？

【解决方案1】：

删除这一行：

r.pause_threshold = 0.8

试试这个：

r.listen(source,timeout=2)

为我工作！

【解决方案2】：

尝试删除暂停阈值并使用：

audio = r.listen(source, phrase_time_limit=5)

【解决方案3】：

你可以试试 query = r.recognize_google(audio,language='En-In')

或

查询 = r.recognize_google(音频)

它对我有用
