Which service region were you using? Could you please try eastasia or southeastasia? https://docs.microsoft.com/en-us/azure/cognitive-services/speech-service/regions

I have tried eastasia region and westus region,both of them return the same error code. I tried to run this app on another PC in China, but still got the same error.
