Prime Video tests AI-assisted dubbing for movies and TV shows

Prime Video just kicked off a test for AI-assisted dubbing on select licensed movies and TV shows, Amazon announced on Wednesday.

Instead of going fully automated, Prime Video is combining AI tech with human localization professionals to keep quality in check. The test is launching in English and Latin American Spanish across 12 catalog titles that previously had no dubbing at all, such as the Spanish animated film El Cid: La Leyenda, family drama Mi Mamá Lora, and indie feature Long Lost.

The streaming translation race

Prime Video is far from the only platform looking at AI to break language barriers. Deepdub already counts Paramount+ as a client, and YouTube recently rolled out an auto-dubbing tool for creators to translate videos into multiple languages.

This isn't Amazon's first AI viewing experiment either. Prime Video already offers X-Ray Recaps to summarize seasons and episodes, alongside Dialogue Boost to make hard-to-hear lines clearer.

Why it matters

For viewers, this opens up smaller foreign titles and indie movies that typically never get the localization budget of a blockbuster. We think starting with un-dubbed, long-tail content is a smart hedge: it avoids alienating fans of major flagship shows while testing whether the hybrid human-AI model actually holds up to scrutiny. As streaming platforms fight for international subscribers, cheap and scalable dubbing could quietly become a major retention lever.
