March 16, 2026 — Google Ads introduces AI voice models as a new asset optimization feature for Performance Max video ads, automatically generating realistic voice-overs using advertisers’ headlines and descriptions for eligible Performance Max campaigns starting March 20.
The feature targets videos without existing voice-overs, aiming to boost viewer engagement and ad performance by layering AI-generated audio onto the visuals, as detailed in Google Ads Help documentation and reported by Search Engine Roundtable.
“Performance Max is rolling out a new asset optimization feature to improve the viewer experience of your video ads. It uses Google AI voice models to add realistic voice-over to video ads, in order to drive user engagement and ad performance.”
This quote comes from a Google email notification sent to advertisers.
How the Feature Works
Google Ads introduces AI voice models as a new asset optimization feature for Performance Max video ads by selecting one of the advertiser’s provided text assets—such as headlines or descriptions—converting it to speech, and merging it with the video to create a new asset.
“To help optimize your videos in Google Ads, you can leverage Google AI to intelligently add voice-over to videos that don’t already one. Google AI will select one of your provided text assets, turn it into voice-over, and merge both pieces of creative to produce a new video asset.”
The enhancement is available only for English-language accounts and Performance Max campaigns with video enhancement control enabled, per the official help page.
Rollout and Opt-Out Details
Activation occurs on March 20, 2026, for all eligible campaigns where video enhancement is not disabled. Advertisers can opt out beforehand via campaign settings under Asset optimization > Video > Enhancement checkbox. No action is required for already opted-out campaigns.
Search Engine Roundtable first covered the rollout on March 10, noting Google’s email alert. Additional reports from PPC Land urged opting out by the deadline.
