His work focuses on enhancing the way transcripts are segmented and visualized, making it easier to understand and analyze spoken content.

Latest Patents

One of Haoran Cai's latest patents is titled "Transcript paragraph segmentation and visualization of transcript paragraphs." This invention provides systems, methods, and computer storage media for segmenting a transcript into paragraphs. In this embodiment, a transcript is segmented to start a new paragraph whenever there is a change in speaker and/or a long pause in speech. If any remaining paragraphs exceed a designated length or duration, they are further segmented using dynamic programming to minimize a cost function that penalizes candidate paragraphs based on divergence from a target paragraph length. This innovative approach allows for a more organized and visually appealing representation of transcripts.

Another notable patent is "Face-aware speaker diarization for transcripts and text-based video editing." This invention offers systems, methods, and computer storage media for face-aware speaker diarization. It combines audio-only and audio-visual speaker diarization techniques to generate a hybrid speaker diarization that links detected faces to detected voices. This technology is particularly useful for videos with small, pixelated faces, as it extracts cropped images of faces from each frame to enhance active speaker detection.
