Takes a recorded call or conversation of up to 60 minutes and returns conversati
Takes a recorded call or conversation of up to 60 minutes and returns conversation metrics computed from word timings and speaker separation: talk time and share per speaker, words per minute, number of turns, interruptions (a speaker starting while the other is still speaking or within 0.2 s), total and longest silence, longest monologue. Required phrases you pass are searched word by word and reported as found or missing with time and speaker; forbidden phrases likewise.
