# Build localized Actions

Actions Builder and the Actions SDK both support localization of your Action.
When you serve your Action in multiple languages, the user-facing content of
your Action requires translation. For example, intents should have multilingual
training phrases.

By default, your Action projects support the following:

- Supports all regions (countries), as long as your users have set their Google
  Assistant device to a geographic region supported by Assistant and a language
  supported by your Actions project.

- Uses a Text-To-Speech voice that corresponds to the user's Assistant locale.
  You can override this behavior and choose a specific TTS voice that doesn't
  change based on the user's Assistant locale.

> [!NOTE]
> **Note:** Locales are constructed using the language set in the Assistant settings and the region set in the device settings. The combination of these needs to form a supported locale. For example, a device set to the Brazil (BR) region and an Assistant device set to en-US results in a en-BR locale, which is not supported by Actions on Google.
