python中的SpeechRecogniton模块太慢

现在不建议使用duration参数。参考StackOverflow问题。
而是使用

phrase_time_limit

timeout

这是使用的代码块

phrase_time_limit

import speech_recognition as srdef myCommand():    r = sr.Recognizer()    with sr.Microphone() as source:        audio = r.listen(source, phrase_time_limit = 5)      try:        command = r.recognize_google(audio).lower()        print("you said: " + command)    except sr.UnknownValueError:        print("Sorry, Cant understand, Please say again")        command = myCommand()    return command

这工作得很好。
