As artificial intelligence makes advertising content easier to produce, distinctive sound and trusted human voices are becoming increasingly important tools for building brand recognition and consumer trust, according to a new Radio Advertising Bureau (RAB) contribution to the Association of National Advertisers (ANA) Newsstand.

In an October 15 article titled "Would Consumers Recognize Your Brand with Their Eyes Closed?," RAB Senior Vice President of Business Development Tammy Greenberg examines how sonic branding, emotional storytelling and radio's established relationships with listeners can help advertisers stand out in an increasingly crowded media environment.

Greenberg notes that while most brands maintain detailed visual identity guidelines, relatively few have established consistent audio identities. Research cited in the article found that visual branding appeared in approximately 92% of more than 2,000 video advertisements analyzed by Ipsos, while audio branding elements appeared in fewer than 10%. Despite their limited use, audio assets were associated with stronger branded attention.

The article also highlights the role of familiar radio and podcast personalities in establishing credibility. A study from Omnicom Media Intelligence and iHeartMedia involving more than 3,500 weekly audio listeners found that host-read advertising outperformed prerecorded commercials in personal connection, brand trust, relevance, search intent and purchase intent.

Trusted hosts produced the strongest results, while longer host-read advertisements generated up to twice the unaided recall of 30-second host reads.

Greenberg also points to a 2026 global study, "Audio: The Secret to Profit & Trust," based on a System1 analysis of 1,260 Effie Award-winning campaigns. The research found that campaigns incorporating audio were 75% more likely to generate profit, 81% more likely to build trust, 81% more likely to increase price insensitivity and 19% more likely to acquire customers compared with campaigns without audio.

The study also found that audio roughly doubled profit for emotionally driven advertising. When audio was combined with distinctive brand elements, including jingles and sonic signatures, the profit index increased 103% compared with campaigns lacking both audio and distinctive assets.

According to Greenberg, radio's broad reach, listening frequency and established place in consumers' daily routines make it particularly effective for developing recognizable audio identities over time. Consistent use of music, voices, jingles and other sonic elements helps audiences associate advertising messages with specific brands.

The article recommends that advertisers develop creative specifically for audio rather than simply adapting visual advertising copy. Effective approaches include establishing the brand early, focusing on one clear message, selecting appropriate voices, incorporating distinctive sounds and allowing trusted radio personalities to communicate naturally.

Greenberg suggests a simple test for advertisers: Remove the final brand mention from an audio commercial and determine whether consumers could still identify the advertiser.

The article concludes that as AI-generated content becomes more common, recognizable audio identities and authentic human connections will become increasingly valuable. Radio's combination of familiar voices, emotional storytelling and consistent audience engagement offers advertisers an opportunity to build lasting brand recognition and trust.
