Azure OpenAI 语音转语音聊天

总体而言：

一个文件—— 自建 python文件 openai-speech.py，代码粘贴即可：

两个依赖—— 使用 pip 安装 azure-cognitiveservices-speech，openai

三个可修改变量：

若要更改语音识别语言，请将 en-US 替换为其他支持的语言。例如，es-ES 代表西班牙语（西班牙）。如果未指定语言，则默认语言为 en-US。若要详细了解如何从多种使用的语言中进行识别，请参阅语言识别。
若要更改你听到的语音，请将 en-US-JennyMultilingualNeural 替换为另一个受支持的语音。如果语音不使用从 Azure OpenAI 返回的文本的语言，则语音服务不会输出合成音频。
若要使用不同的模型，请将 text-davinci-002 替换为另一个部署的 ID。请记住，部署 ID 不一定与模型名称相同。你是在 Azure OpenAI Studio 中创建部署时为其命名的。

四个环境变量：

setx OPEN_AI_KEY your-openai-key
setx OPEN_AI_ENDPOINT your-openai-endpoint
setx SPEECH_KEY your-speech-key
setx SPEECH_REGION your-speech-region

附代码：
