Abstract
An emotion recognition apparatus performs accurate and stable speech-based emotion recognition, irrespective of individual, regional, and language differences of prosodic information. The emotion recognition apparatus includes: a speech recognition unit which recognizes types of phonemes included in the input speech; a characteristic tone detection unit which detects a characteristic tone that relates to a specific emotion, in the input speech; a characteristic tone occurrence indicator computation unit which computes a characteristic tone occurrence indicator for each of the phonemes, based on the types of the phonemes recognized by the speech recognition unit, the characteristic tone occurrence indicator relating to an occurrence frequency of the characteristic tone; and an emotion judgment unit which judges an emotion of the speaker in a phoneme at which the characteristic tone occurs in the input speech, based on the characteristic tone occurrence indicator computed by the characteristic tone occurrence indicator computing unit.
