Topic Segments API
Takes a recording of up to 120 minutes and returns its topic structure: segments that start where the subject really changes, each with a topic label of up to eight words, keywords, a one-sentence summary, start and end time and the spoken text of the segment. Boundaries are chosen by a language model as sentence numbers only, so they always fall on sentence starts with recogniser timestamps. Maximum number of segments and output language are selectable.
