Analysis of prosodic features towards modelling of emotional and pragmatic attributes of speech

Although speech technologies keep improving their performance, it is necessary to understand the mechanisms used in speech to transmit, a part from lexical, other information such as emotion, attitude or speaker styles. In this work we have focused on the study of the correlation of basic prosodic features with emotional and pragmatic characteristics. For that purpose, three corpora have been used: emotional recorded speech, a read tale and Spanish parliament recordings. Based on an emotion and discourse modes taxonomy, we performed a classifying task of such characteristics by means of the prosodic features. Preliminary results show that emotions can be identified from prosody and that also exists a correlation between prosody and pragmatic attributes.
