在Python中使用Speech_Recognition在终端中获取不需要的输出

问题描述

我使用一个名为“ speech_recognition”的库编写了此代码，该库使用麦克风获取用户的讲话并将其打印到终端中。
代码是这样的：

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)

我希望它首先print('Give command')，然后听音频并打印出听到的声音。
它确实做到了，但这就是我说“你好，请帮助”时得到的全部输出：

Give command
hello please help

输出的最后两行是我想看到的唯一内容。

解决方法

如果您使用的是Speech_recog。像语音助手之类的库，最好不要使用终端显示o / p。而是以语音形式输出。这使应用程序变得更好，并且摆脱了所有这些垃圾警告
