Audible is developing an AI translation service for publishers that can either translate a manuscript's text into another language or translate the finished audio while preserving the original narrator's voice. The service was announced in May 2025, with a beta expected later that year.

Two translation pathways are offered. The first converts manuscript text from English into Spanish, French, Italian, or German, which publishers can then pair with human or AI narration. The second is a speech-to-speech translation that carries across the original narrator's voice, delivery, and style into a new language — a process that previously required hiring separate narrators for each language. Publishers may also request a human review from professional linguists for accuracy and cultural nuance. The service automates what has historically been a costly manual localization process that put most non-English audiobook translation out of reach for all but the largest publishers.
