I am following the document here( https://docs.microsoft.com/en-us/azure/cognitive-services/speech-service/get-started-text-to-speech?tabs=script%2Clinuxinstall&pivots=programmer-tool-spx) to quick start a tts on CentOS 8.2 with Speech CLI.
When running sample command "spx synthesize --text "The speech synthesizer greets you!" --audio output greetings.wav"
I got the following error
SYNTHESIS STARTED: c88154c****e33c80
CANCELED: Reason=Error
CANCELED: ErrorCode=ConnectionFailure
CANCELED: ErrorDetails=Connection failed (no connection to the remote host). Internal error: 1. Error details: Code: 2542. USP state: 2. Received audio size: 0 bytes.
CANCELED: Did you update the subscription info?
Please help. Thanks.
