Subscription Key for Azure TTS/STT

Question

Hi Team,

We're using the Java SDK for Azure Text-to-Speech (TTS) and Speech-to-Text (STT). The SDK initialization requires a subscription key and region. Does a single subscription key work across all Azure regions, or do clients need to generate separate subscription keys for each region?

Regards,

Ananth

Hello @Ananth Hegde (anahegde),

Greetings and Welcome to Microsoft Q&A! Thanks for posting the question.

In Azure, subscription keys for the Speech service, including Text-to-Speech (TTS) and Speech-to-Text (STT) is region-specific, a subscription key created in a specific region works exclusively for resources and endpoints within that region. Clients cannot use a single subscription key across multiple regions. For example, if you create a Speech resource in the eastus region, the subscription key generated for this resource will only work with endpoints in eastus. If you need to use the service in another region, such as westeurope, you must create a separate Speech resource in that region with its corresponding subscription key.

Kindly refer this Speech service supported regions.

I hope you understand. And, if you have any further query do let us know.
