Question

嗨，我正在尝试在代码中触发while循环，以便每当说出“处女座”这个热门单词时就开始语音识别。问题是snowboy可以检测到该热门单词，但是一旦触发该热门单词，我就不知道如何执行“ while”循环。有什么帮助吗？这听起来可能很愚蠢，应该相对容易一些，但是我的大脑现在正着火。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

在给定while的情况下，您的TRUE循环始终被“触发”，直到您break从中退出。要在循环内触发代码，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
