在 Python 中使用语音识别在终端中获取不需要的输出

维雷吉·达萨尼

我使用名为“speech_recognition”的库编写了这段代码，其中它使用麦克风来获取用户所说的内容并将其打印到终端中。
这是代码：

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print('Give command')是它听音频并打印出它听到的内容。
它确实这样做了，但这是我说“你好，请帮忙”时得到的整个输出：

Give command
hello please help

输出的最后两行是我唯一想看到的。

如果您使用的是语音识别。像语音助手这样的库，最好不要使用终端来显示 o/p。相反，在语音中输出。这使应用程序更好，并摆脱了所有这些垃圾警告
