AWS Elemental Inference now supports Smart Subtitles for automated live captioning

AWS Elemental Inference now supports smart subtitles, a new AI-powered feature that automatically generates real-time subtitles for live video streams. Smart subtitles use advanced speech recognition to transcribe spoken audio and deliver Timed Text Markup Language (TTML)-formatted subtitles with low latency, helping broadcasters and streamers provide accessible content to viewers without manual captioning workflows or third-party services.

With Smart subtitles, you can add live subtitling for content that is English (United States, Great Britain, and Australian), French, German, Italian, Portuguese, and Spanish to your broadcasts by enabling the feature through the native integration with AWS Elemental MediaLive. You can improve transcription accuracy for specialized content—such as sports commentary with athlete names or technical terminology—by creating custom dictionaries through the AWS Elemental Inference API or console. Smart subtitles work alongside existing Elemental Inference features like smart cropping for vertical video and clip generation, and you benefit from the same non-linear pricing that reduces per-feature costs when using multiple features simultaneously on the same content.
