Can’t Access UK English or German-language Skills?

In order to access skills in these other regions, users must change Amazon stores.

On Amazon: Your Account > Manage Your Content and Devices > Country Settings > [UK or German address].

  • → Users who use a UK/German address can only enable skills available in their respective regions.
  • → Users who use a US address can only enable skills available in the United States.

For language switching only:

The SettingsUpdated event allows a product to switch Alexa’s language (en-US, en-GB, de-DE) through an on-device control or a companion app. Language switching allows users to converse with Alexa in any supported language regardless of endpoint. For example, German speakers in the US can access US-based Alexa skills and converse with Alexa in German, provided that the skill supports German.
