Skills for this task

The Beatra Skill covers everything on this page. These Skills add a ready-made workflow for one task:

Questions

Can I use my own voice?

Yes. Give the agent a 10 to 300 second recording of your own voice and confirm you have the right to use it. The cloned voice is saved to your account for later narration.

Can it fit narration to my video's length?

Tell the agent the length you need. The short-video voiceover Skill makes the wording easy to say and reports the real duration of the audio it returns, so you can tighten the script and render again.

Where do the audio files go?

They come back into your agent conversation and are saved on the Work page of the Beatra console.
