Azure认知服务-语音示例代码因身份验证错误而失败

Question

程序返回：CANCELED：原因=错误ErrorDetails = WebSocket升级失败，出现身份验证错误（401）。请检查正确的订阅密钥（或授权令牌）和区域名称。 SessionId：cbfcdf7f26304343a08de6c398652053

您上面粘贴的示例代码仍然具有placeholder值的区域和订阅密钥。只是仔细检查您是否确实用您自己的订阅密钥和区域替换了这些字符串？如果是这样，您能否打开日志记录，再次运行代码，然后提供日志？我们可以从那里帮助诊断...

要打开日志记录，请参见https://aka.ms/speech/logging。>>
