Abstract

Recognizing human emotions/attitudes from speech cues has gained increased attention recently. Most previous work has focused primarily on suprasegmental prosodic features calcu-lated at the utterance level for modeling against details at the segmental phoneme level. Based on the hypothesis that dif-ferent emotions have varying effects on the properties of the different speech sounds, this paper investigates the usefulness of phoneme-level modeling for the classification of emotional states from speech. Hidden Markov models (HMM) based on short-term spectral features are used for this purpose using data obtained from a recording of an actress ’ expressing 4 different emotional states- anger, happiness, neutral, and sadness. We designed and compared two sets of HMM classifiers: a generic set of “emotional speech ” HMMs (one for each emotion) and a set of broad phonetic-class based HMMs for each emotion type considered. Five broad phonetic classes were used to explore the effect of emotional coloring on different phoneme classes, and it was found that spectral properties of vowel sounds were the best indicator of emotions in terms of the classification per-formance. The experiments also showed that the better per-formance can be obtained by using phoneme-class classifiers than generic “emotional ” HMM classifier and classifiers based on global prosodic features. To see the complementary effect of the prosodic and spectral features, the two classifiers were combined at the decis…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
