# Kling Voice Management

> Create and manage reusable custom voices or browse Kling preset voices.

Voice management creates reusable voice IDs for supported Kling video generation requests. A custom voice can be created from a clean audio/video URL or from an eligible historical generated video.

## Source requirements

* `voice_url` supports MP3, WAV, MP4, and MOV.
* Use a clean recording containing exactly one human voice.
* Source duration must be 5–30 seconds.
* Alternatively, provide an eligible `video_id` from a Kling 2.6 task with sound enabled, an Avatar task, or a Lip-Sync task.
