Resumo

Different levels of affects are expressed in different levels of speech processing: expressions of emotions linked to an involuntarily triggered control, expressions of the speaker's attitudes and intentions and meta-linguistic expressive strategies. C-Clone is presented as an interactive cognitive architecture of the expressive communication. Authentic but controlled expressive corpora have been collected using a Wizard of Oz experimental platform (E-Wiz) The acoustic as well as video and some physiological signals were recorded synchronously. An auto-annotated subset of emotional expressions made possible the validation of the modeling of affective prosody into gradient contours. Moreover perceptive experiments show that no prosodic dimension is specific of an emotional value.
