SnowBoy热词检测问题

Question

大家好，我正试图在我的代码中触发while循环，每当说到"virgo“这个热词时，它就会启动语音识别。问题是snowboy检测到了hotword，但是一旦hotword被触发，我不知道如何执行"while“循环。有什么需要帮忙的吗？这听起来可能很愚蠢，应该相对容易，但我的大脑现在着火了。谢谢!

import speech_recognition as sr
from textblob import TextBlob
import snowboydecoder

recognizer_instance = sr.Recognizer()

def detected_callback():
    print ("tell me!")

detector = snowboydecoder.HotwordDetector("virgo.pmdl",sensitivity=0.5)

detector.start(detected_callback=snowboydecoder.play_audio_file,sleep_time=0.03)
detector.terminate()


while True:
    with sr.Microphone() as source:
        recognizer_instance.adjust_for_ambient_noise(source)
        print("Listening...")
        audio = recognizer_instance.listen(source)
        print("copy that!")

    try:
        text = recognizer_instance.recognize_google(audio, language = "it-IT")
        print("you said:\n", text) 

    except Exception as e:
        break

给定TRUE，你的while循环总是被“触发”的，直到你break退出它。要触发循环内的代码，请执行以下操作：

while True:
    if YOUR_TRIGGER_CONDITION:
        with sr.Microphone() as source:
            recognizer_instance.adjust_for_ambient_noise(source)
            print("Listening...")
            audio = recognizer_instance.listen(source)
            print("copy that!")

        try:
            text = recognizer_instance.recognize_google(audio, language = "it-IT")
            print("you said:\n", text) 

        except Exception as e:
            break
