#Customer intent: As a developer, I want to learn about the available regions and endpoints for Azure Speech so that I can decide how to use the features in my application.

# Supported regions for Azure Speech

Azure Speech allows your application to convert audio to text, perform speech translation, and convert text to speech. Azure Speech is available in multiple regions with unique endpoints for the Speech SDK and REST APIs.

Keep in mind the following points:

- If your application uses the [Speech SDK](speech-sdk.md), you provide the region identifier (such as `westus`) when you create a `SpeechConfig` instance. Make sure that the region matches the region of your Azure Speech resource.
- If your application uses one of the Azure Speech REST APIs, the region is part of the endpoint URI that you use when making requests.
- Keys created for a region are valid only in that region. If you try to use them with other regions, you get authentication errors.

> [!NOTE]
> Azure Speech doesn't store or process your data outside the region of your Azure Speech resource. The data is stored or processed only in the region where the resource is created. For example, if you create a Foundry resource for speech in the `westus` region, the data is only in the `westus` region.

## Regions

The regions in the following tables support most of the core features of Azure Speech, such as speech to text, text to speech, and translation. Some features, such as fast transcription and batch synthesis, require specific regions. For the features that require specific regions, the tables indicate the regions that support them.

<sup>1</sup> Supports the processing of custom speech models.

<sup>2</sup> The region uses dedicated hardware for custom speech training. If you plan to train a custom model, you must use one of the regions that have dedicated hardware. Then you can [copy the trained model](how-to-custom-speech-train-model.md#copy-a-model) to another region.
