Method, apparatus and program capable of outputting response perceivable to a user as natural-sounding

摘要

A voice synthesizing apparatus includes: a voice inputter (102) configured to input a voice; an obtainer (22) configured to obtain a primary response to the voice inputted by the voice inputter (102); an analyzer (112) configured to analyze whether the primary response includes a repetition target; and a voice synthesizer (24) configured to, in a case where the analyzed primary response is determined to include the repetition target, synthesize a voice from a secondary response that includes the repetition target repeated at least twice to output the voice.
