ACX, Audible's creator submission platform, uses automated systems to screen uploaded audio files for technical compliance and to monitor creator accounts for policy violations — including detecting duplicate accounts across Amazon services. Files that don't pass automated checks cannot be submitted.
Details
ACX's published guidelines describe cross-platform account monitoring: if a creator opens a duplicate account to circumvent rules, all related accounts are disabled, and standing is verified across Amazon services including KDP and the Amazon Associates program. Audio submissions go through automated technical verification before reaching a human quality control reviewer. The extent to which the account monitoring system uses machine learning versus rule-based logic is not publicly confirmed; Amazon's broader platform infrastructure likely underlies the cross-platform detection capability. This is a combination of rule-based automation and platform-level AI applied to the ACX creator community.

Other practices by Audible
OtherAudible is deeply integrated with Amazon's Alexa voice assistant, allowing listeners to control playback, browse titles, and navigate their library entirely by voice — without touching a screen. This works on Echo smart speakers, within the Audible app itself (via a built-in Alexa button), and on Ray-Ban Meta smart glasses.OtherAudible Captions was a feature announced in July 2019 that would display real-time text captions of audiobooks on screen using AI speech-to-text technology — similar to subtitles for audio. It was blocked by a copyright lawsuit filed by seven major book publishers before it could fully launch, and was discontinued following a settlement in January 2020.OtherAudible launched a feature in mid-2025 (U.S. beta) that lets listeners ask questions about the audiobook they are currently listening to — without pausing playback. Listeners tap the app and type a question; an AI-generated answer appears on screen within about one second. Initially available for classic and public domain titles.
