如何解决Python语音识别脚本出现“BaseException is not allowed”报错

你代码中的except语句存在语法错误：Python的异常捕获语法要求except关键字后跟随异常类本身，你当前代码写的是except speech_recognition.UnknownValueError():，末尾额外添加的括号会触发异常类的实例化，except接收到的是异常实例而非异常类型，因此触发该类型错误。

直接删除UnknownValueError后的括号即可，修正后的完整代码如下：

import speech_recognition
import pyttsx3

recognizer = speech_recognition.Recognizer()

while True:
    try:
        with speech_recognition.Microphone() as mic:
            recognizer.adjust_for_ambient_noise(mic, duration=0.2)
            audio = recognizer.listen(mic)

            text = recognizer.recognize_google(audio)
            text = text.lower()

            print(f"Recognized {text}")

    except speech_recognition.UnknownValueError:
        recognizer = speech_recognition.Recognizer()
        continue
