AWS Elemental Inference has launched 'smart subtitles', an AI-powered feature for automated, real-time live captioning for video streams. This new functionality utilizes advanced speech recognition to generate Timed Text Markup Language (TTML) formatted subtitles with low latency in multiple languages, improving content accessibility for broadcasters and streamers. Users can also create custom dictionaries to enhance transcription accuracy for specialized content.
This gives broadcasters and streamers a built-in path to live captioning without manual workflows or third-party services, using AWS Elemental Inference and native MediaLive integration. It also folds subtitles into the same Elemental Inference stack as smart cropping and clip generation, with non-linear pricing applying when multiple features run on the same content. The next thing to watch is adoption of custom dictionaries, especially for specialized live formats like sports commentary and technical programming.
