Speech evaluation system, speech evaluation method, and non-transitory computer readable medium storing program

Abstract

A speech detection unit detects a speech in communication based on output values of microphones of a plurality of wearable terminals, and identifies a wearable terminal corresponding to the detected speech. A speech period detection unit detects for each speech a start timing of the speech and an end timing thereof. An evaluation-value calculation unit calculates, for each speech detected by the speech detection unit, an evaluation value for the speech based on an output value of an acceleration sensor of a wearable terminal other than the wearable terminal corresponding to the speech in an evaluation period from a first timing, which is at or later than the start timing of the speech and earlier than the end timing of the speech, to a second timing, which is later than the end timing of the speech.
