我使用一个名为"演讲_认知"；其中其使用所述麦克风来获取用户讲话内容并将其打印到所述终端中
这就是代码：
import speech_recognition as sr
import webbrowser as wb
r1 = sr.Recognizer()
r2 = sr.Recognizer()
with sr.Microphone() as source:
print('Give command')
audio = r1.listen(source)
command = r2.recognize_google(audio)
print (command)
我希望这首先是print('Give command')，然后是听音频并打印出它听到的内容
它确实做到了，但这是我说-"；你好，请帮忙"：

Give command
hello please help
输出的最后两行是我唯一想看到的内容。
如果您使用的是speech_recog。对于语音助手之类的程序库，最好不要使用终端来显示o/p。相反，用语音输出。这使应用程序变得更好，并消除了所有这些垃圾警告
