Python语音助手唤醒单词检测

如何解决Python语音助手唤醒单词检测

我在python中有一个正在运行的语音助手，但是目前它一直在监听，我理想地希望它开始听类似于“嘿Google”的唤醒字。

有人可以帮忙吗？

下面的代码段

voices = engine.getProperty('voices')
engine.setProperty('voice',voice_id)

keyword = "jarvis"
r = sr.Recognizer()


def speak(text):
   engine.say(text)
   engine.runAndWait()


def wishMe():
   hour = datetime.datetime.now().hour
   if 0 <= hour < 12:
       speak("Hello chris,Good Morning")
       print("Hello,Good Morning")
   elif 12 <= hour < 18:
       speak("Hello chris,Good Afternoon")
       print("Hello,Good Afternoon")
   else:
       speak("Hello chris,Good Evening")
       print("Hello,Good Evening")


def takeCommand():
   with sr.Microphone() as source:
       speak("yes chris...")
       r.adjust_for_ambient_noise(source)
       audio = r.listen(source,phrase_time_limit=5)

       try:
           statement = r.recognize_google(audio,language='en-uk')
           print(f"user said:{statement}\n")

       except Exception as e:
           speak("sorry i couldn't understand")
           return "None"
       return statement


speak("Loading jarvis")
wishMe()
