Speech regeneration

Not happy with how a paragraph sounds? Now you can regenerate the voiceover and retry until the emphasis and delivery feel exactly right — and once you land on a version you like, it stays consistent with your avatar's performance, saving you time and eliminating the need to keep re-generating or re-checking.

Try it out by highlighting the text, click regenerate to create new audio for the entire paragraph, and if you like the result we'll save it automatically.

Voice speed controls

You can now adjust voice speed directly in the editor — slow down for complex terms, names, or key moments, and speed up to match your pacing, so every voice sounds exactly right for your content.

Just select the voice, find the speed control next to the voice selector, and adjust how fast it speaks. Your change will apply to the selected voiceover in the scene, and you can also apply it to the same voice in all scenes.

Let us know what you think and… happy creating!
