# Heygen Video-translate

Translate videos into 175+ languages with natural voice cloning and precise lip-syncing.

<Tip>
  This is an **asynchronous** API and only returns the `task_id` of the async task. You should use this `task_id` to request the [Get Task Result API](/en/docs/models/reference-get-async-task-result) to retrieve the generated result.
