Required env vars

export AZURE_SPEECH_KEY="YOUR_SPEECH_RESOURCE_KEY"
export AZURE_SPEECH_REGION="eastus"

How to get the API key and region

Go to the Azure portal and open your Speech or Foundry Speech resource.
Open Keys and Endpoint.
Copy one of the resource keys.
Copy the resource region, for example eastus.
Export them:

export AZURE_SPEECH_KEY="YOUR_SPEECH_RESOURCE_KEY"
export AZURE_SPEECH_REGION="eastus"

The MAI-Voice docs currently point at East US for preview access, so if you are not using eastus, double-check that your resource actually supports the model before blaming the script.

Optional:

export AZURE_SPEECH_OUTPUT_FORMAT="audio-24khz-160kbitrate-mono-mp3"
