Takes a conversation, call, focus group or meeting of up to 60 minutes, separate
Takes a conversation, call, focus group or meeting of up to 60 minutes, separates speakers, splits it into time windows (default 60 seconds) and returns a sentiment timeline: per window and speaker a score from -1 to +1, a label such as tense, pleased or annoyed, and a verbatim quote that is checked against the transcript. Also returned are the average per speaker, the largest changes as turning points with time, and talk share per window computed from word timings.
