Python speech_recognition模块报错：无'recognize'属性的技术问询

运行基于speech_recognition库的Python语音交互代码时，触发错误提示：

An error occurred : module 'speech_recognition' has no attribute 'recognize'

错误根源 #

代码中这一行写法错误：

recognizer=sr.recognize()

正确写法应为：

recognizer=sr.Recognizer()

Recognizer是库中的类，需首字母大写且加括号实例化对象，小写的recognize并非库的顶层属性，因此触发该错误。

额外代码修正提示 #

除核心错误外，代码还有几处拼写和调用问题需修正：

• transcribe_audio_to_test函数中，变量recogizer拼写错误，应改为recognizer
• generate_response函数中，response["Choices"]的键名应为小写choices，否则会触发KeyError
• 打印语句中的yuo应为you，resopnse应为response

修正后的完整代码 #

openai.api_key = "myapikey"
