What 14 Industry Studies Say About Consumer Trust in AI Voices

If you work in advertising, media, or voiceover, you've probably heard strong opinions about AI-generated voices. Some say they're the future. Others say audiences don't want them. We wanted to see what the data actually says.

We went through 14 published studies from organizations like the IAB, Pew Research Center, Edelman, CivicScience, Jacobs Media, Kantar, and others. We pulled out the key findings, verified each stat against its original source, and put it all in one place.

The result is our AI Voice Sentiment Index, an interactive dashboard where you can explore the data yourself.

The short version

Consumers are skeptical of AI voices in advertising, and that skepticism is growing.

• 75% of radio listeners oppose AI cloned voices replacing human talent (Jacobs Media, 29,000+ respondents)
• Only 13% of consumers trust ads created entirely by AI (Smartly.io)
• 41% of consumers say AI-generated ads bother them (Kantar)
• 81% of Americans are concerned about the implications of AI voice technology (Podcastle/Async, 1,000 respondents)

The perception gap

One of the most striking findings comes from the IAB. In their 2026 study, 82% of ad executives believed Gen Z and Millennial consumers feel positively about AI-generated ads. The actual number? 45%. That's a 37-point gap, and it widened from 32 points just a year earlier.

Consumers are also more likely than ad executives to describe brands using AI as "manipulative" (20% vs 10%) or "unethical" (16% vs 7%).

Gen Z is the most skeptical generation

This surprised us. You might expect the most digitally native generation to be the most comfortable with AI. But according to the IAB data, 39% of Gen Z report negative feelings toward AI ads, compared to 20% of Millennials.

Pew Research found a similar pattern: 61% of adults under 30 say AI will make people worse at thinking creatively.

The counter-evidence

We included data that complicates the narrative because we think it matters. Not everything points negative.

Smartly.io found that 48% of consumers trust ads co-created by a person with AI support, compared to just 13% for fully AI-created ads. Human involvement is the differentiator.

Attest found that objection to AI-generated models in advertising fell from 49% to 46% year over year. A small decline, but directionally different from the other trends.

Our disclosure

RealVOTalent is a human voice talent marketplace. We have a business interest in this topic. That's why we included counter-evidence, flagged conflicts of interest in our sources (Podcastle is an AI company, the Veritonic study was funded by an AI ad platform), and disclosed our own position.

The data should stand on its own. If it doesn't support our case, we'd rather know that than pretend otherwise.
