找一个可实现的语音唤醒代码

以下是使用Python实现语音唤醒的示例代码：

1. 安装需要的库

pip install pyaudio
pip install SpeechRecognition

2. 代码实现

import speech_recognition as sr

# 初始化识别器和麦克风
r = sr.Recognizer()
mic = sr.Microphone()

# 定义唤醒词和对应的响应函数
wakeup_words = ['你好', '你在吗']
def on_wakeup():
    print('听到了唤醒词！')

# 定义语音识别函数
def recognize_speech():
    with mic as source:
        print('开始录音...')
        r.adjust_for_ambient_noise(source)
        audio = r.listen(source)
    try:
        text = r.recognize_google(audio, language='zh-CN')
        print('识别结果:', text)
        if text in wakeup_words:
            on_wakeup()
    except sr.UnknownValueError:
        print('听不清楚，请再说一遍。')
    except sr.RequestError as e:
        print('请求出错：{0}'.format(e))

# 循环监听语音输入
with mic as source:
    r.adjust_for_ambient_noise(source)
print('语音唤醒已启动')
while True:
    recognize_speech()

以上代码会监听麦克风，如果检测到唤醒词，就会执行`on_wakeup()`函数。可以将`on_wakeup()`替换成其他需要的操作或语音交互功能实现。
