A new Voiceover Video Enhancement feature has been introduced for Performance Max and Demand Gen campaigns. It builds on Google’s existing video enhancement tools, which already support creating vertical and shorter versions of videos, by automatically generating voiceovers using Google AI and converting text assets into audio to enhance video content.
Advertisers can access this feature at the campaign level in Performance Max under Asset Optimization, and at the ad level in Demand Gen. Google provides a preview of the results, allowing users to review and manage the generated voiceovers before they go live.

Currently, this feature is only available for English accounts. The voiceovers are created using existing headlines and descriptions, therefore, the quality of these assets is crucial.
