🎧 New Audio Advertising Study Finds Personalized AI-Generated Ads Are 22% More Effective at Increasing Brand Favorability

Third-party research comparing generic and personalised AI-generated audio ads to a control group exposed to neither was released today by Instreamatic, whose advanced voice and audio marketing solutions help brands engage with consumers. A dentsu Intel campaign was studied by audio research and analytics platform Veritonic.

The audio ad campaign measured brand awareness, favorability, purchase intent, and memorability for the Intel® Evo™ Edition laptop. Three audiences were surveyed: one exposed to listener-personalized AI-generated audio ads, one to generic ads, and a control group. 48 hours after hearing ads on streaming radio and podcasts, the same audience was contacted and surveyed to measure brand metrics.

“The top-line takeaway from this audio ad campaign study is that AI-generated ads work—and personalized AI-generated ads work even better,” said Carolyn Henry, Intel Vice President Americas Regional Marketing. “With dentsu, we quickly launched an audio ad campaign with unique personalization that captured more attention—and favorable attention—from our target audience. The time and cost efficiencies producing this campaign were also key since we can create, deploy, and iterate personalized AI-generated ads without recording multiple ad versions.”

Veritonic’s study results indicate a consumer readiness for AI-generated audio ads, with both generic and personalized AI ad variations outperforming the control group. Audio ads with personalized, context-driven creative also decisively outperformed those with generic creative. Among the quantitative conclusions from the study:

▪ Personalized ads increased brand favorability by a staggering 18-22 percentage points. While generic AI-generated creative increased brand favorability by 9% over those not exposed to the campaign, personalized AI-generated creative across all platforms drove significant brand favorability lifts as high as 22 percentage points. Additionally, 62% of those exposed to personalized ads reported they were likelier to think favorably of a brand that personalizes its message.

▪ Personalized ads boosted purchase intent by 15-18 percentage points. By comparison, generic AI creative drove a 3% increase. Additionally, 60% of those exposed to the personalized AI campaign reported being more likely to consider purchasing from a brand offering personalized ads.

▪ Listening to personalized ads increased brand awareness by 6-12 percentage points. Additionally, 73% of those hearing personalized AI-generated ads reported being more likely to pay attention to ads personalized just for them.

Instreamatic’s AI-fueled audio ad technology provides voice AI capabilities that allow agencies and brands to generate entire campaigns—including thousands of personalized and creative ad variations—from a single original voice sample and script. Instreamatic’s platform identifies parameters unique to each listener’s current environment, enabling contextual audio ads to include hyper-personalized details. For example, ads can mention the listener’s location, the time of day, their current activity (such as listening to a podcast), and the app or platform they use for that activity. Personalized AI-generated ads can also include the nearest store and address where the listener can redeem an offer, promo codes for performance tracking, and more.

“Consumers want brands to speak to them as individuals,” said Amy Siegel, VP, Innovation at dentsu. “It’s a big deal when a brand can go the extra mile and stand apart by providing more unique and memorable interactions. Instreamatic’s technology gives brands that voice. As this study’s findings bear out, the impact of AI-generated personalized ads on brand awareness, favorability, and purchase intent can make a big impact.”

The study also shows how AI can be strategically used to generate better campaign results with a fraction of the time and cost expenditures required by traditional audio ads. Where a single traditional audio campaign creative would require extensive studio costs and 4-6 weeks to produce, Instreamatic’s platform can prepare that same ad in three minutes. Where recording thousands of ad versions personalized and contextualized to each listener would require months of voice work and be virtually impossible to execute, Instreamatic can prepare entire campaigns in just hours.

“The Veritonic study confirms that audiences are much more receptive to engagement efforts—including those built intelligently and respectfully with AI—that value them as individuals and speak to their specific lives and needs,” said Stas Tushinskiy, CEO, Instreamatic. “We’re proud of our work with Intel and dentsu and look forward to enabling more brands to usher in this new era of more personal and effective audio advertising.”

“We are proud to provide Instreamatic, dentsu, and Intel with insightful and actionable data that underscored the power of personalized audio ads,” said Scott Simonelli, CEO and Founder of Veritonic. “Brands today are continuously challenged to cut through the noise across a wealth of platforms. By creating personalized, relevant ads, their message will not only reach but resonate with their target audiences, contributing to an increase in meaningful brand awareness and engagement.”
