The new AI-powered captioning solution can reduce time spent captioning by 80% and cost by 50%, but it would still require human oversight at first.

Warner Bros. Discovery (WBD) is partnering with Google Cloud to generate closed captioning for content on the studio’s Max streaming service in the US. WBD will use a new “caption AI” solution that runs on Google Cloud’s Vertex AI platform to generate speech-to-text for some shows, starting with “unscripted programming.”

Warner Bros. Discovery (WBD) has agreed a deal with Google Cloud to use the latter's Vertex AI to generate captions for programming across a variety of platforms. WBD claims that its Caption AI system can significantly reduce production time and costs while improving the accuracy of captions for US-based viewers.
