A nonverbal information generation apparatus includes a nonverbal information generation unit that generates time-information-stamped nonverbal information that corresponds to time-information-stamped text feature quantities and an expression unit that expresses the nonverbal information on the basis of the time-information-stamped text feature quantities and a learned nonverbal information generation model. The time-information-stamped text feature quantities are configured to include feature quantities that have been extracted from text and time information representing times assigned to predetermined units of the text. The nonverbal information is information for controlling the expression unit so as to express behavior corresponding to the text. The nonverbal information generation unit controls the expression unit so that the time-information-stamped nonverbal information is expressed from the expression unit in accordance with time information assigned to the nonverbal information, and controls the expression unit so that the text or voice corresponding to the text that corresponds to the time information is output.
