A study by Edison Research, released by Spoken, the AI Audiobook Company, found that Spoken’s multi-cast narration outperformed conventional human narration in engagement, favorability, and perceived quality. The study randomized over 1,000 adult U.S. fiction audiobook listeners into two blinded cohorts, each experiencing samples of a new sci-fi thriller as either a professional, single-narrator human production or an unedited, one-click Spoken Multi-Cast™ narration. Key findings showed Spoken Multi-Cast™ achieved higher ratings than human narration in overall favorability (61% vs. 53%), perceived quality of narration (66% vs. 60%), and overall engagement (58% vs. 49%) for character-driven stories. While only 31% of listeners said they’d be likely to listen to an AI audiobook at the start of the survey, after hearing an excerpt, 65% said they’d be likely to listen to an audiobook narrated using Spoken Multi-Cast™.
