Iris Flex’s AI Gap Study Reveals U.S. Consumers Are Embracing Voice Interaction Over Touch When Engaging with AI

Consumers are twice as more likely to speak to their car dashboards and smart home devices (56%) than use touch (31%), according to a study conducted by Iris Flex. Four in 10 talk to their apps (37%) or type (40%). Voice competes head-on with tactile choices across AI-powered systems. The shift toward voice as a preferred interface opens pathways for advertisers, device makers and publishers to engage intuitively with consumers.

“As our voice interactions with AI evolve, advertisers can unlock new possibilities by aligning their strategies with consumer preferences,” notes Idil Cakim.

The convergence of voice interfaces and the audio content ecosystem presents opportunities:

1- Audio engagement: Voice-command technology streamlines audio consumption, from playing podcasts on smart speakers to switching radio stations in cars. This frictionless access boosts engagement, giving audio publishers with smart speaker and drive-time audiences a competitive edge.

2- Short purchase cycle: Advertisers can tailor their ads, pairing content with voice-based commands. For example, a podcast listener might hear a voice-activated call to action such as, “Say order now.”

3- Voice-first environments: Brands can amplify both reach and relevance by crafting content and ads optimized for devices and retail, hospitality, travel and healthcare related locations.

“As our voice interactions with AI evolve, advertisers can unlock new possibilities by aligning their strategies with consumer preferences,” adds Cakim.

Methodology: The AI Gap Study is an online survey conducted by Iris Flex in partnership with TestSet, a leading provider of consumer insights data, in February 2025. It is based on a nationally representative sample of n=1,003 U.S. adults (P18+). The sample is census-balanced on age, gender and region metrics.
