# New Dubbing & Assets APIs

* [**Dubbing API**](https://docs.synthesia.io/reference/dubbing) now available: automatically translate and re-voice video content into multiple target languages.
* [**Assets API**](https://docs.synthesia.io/reference/assets-1) added for managing uploaded files (video, image, audio) used as input for Dubbing and Video APIs.
* Assets API supports large file uploads via temporary AWS S3 credentials with multipart upload.
* See the [step-by-step guide](https://docs.synthesia.io/reference/upload-large-files-via-temporary-aws-credentials) for end-to-end dubbing workflows.
