This paper describes how the visual and acoustic characteristics of some Italian phones (/’a/, /b/, /v/) are modifled in emotive speech by the expression of joy, surprise, sadness, disgust, anger, and fear. In this research we speciflcally analyze the interaction between labial conflgurations, peculiar to each emotion, and the articulatory lip movements of the Italian vowel /’a/ and consonants /b/ and /v/, deflned by phonetic-phonological rules. This interaction was quantifled examining the variations of the following parameters: lip opening, upper and lower lip vertical displacements, lip rounding, anterior/posterior movements (protrusion) of upper lip and lower lip, left and right lip corner horizontal displacements, left and right corner vertical displacements, and asymmetry parameters calculated as the difierence between right and left corner position along the horizontal and the vertical axes. Moreover, we present the correlations between articulatory data and the spectral features of the co-produced acoustic signal.

INTERFACE is an integrated software implemented in Matlab© and created to speed-up the procedure for building an emotive/expressive talking head. Various processing tools, working on dynamic articulatory data physically extracted by an optotracking 3D movement analyzer called ELITE, were implemented to build the animation engine and also to create the correct WAV and FAP files needed for the animation. By the use of INTERFACE, LUCIA, our animated MPEG-4 talking face, can copy a real human by reproducing the movements of passive markers positioned on his face and recorded by an optoelectronic device, or can be directly driven by an emotional XML tagged input text, thus realizing a true audio/visual emotive/expressive synthesis. LUCIAs voice is based on an Italian version of FESTIVAL - MBROLA packages, modified for expressive/emotive synthesis by means of an appropriate APML/VSML tagged language.

Audio/visual speech, in the form of labial movement and facial expression data, was utilized in order to semi-automatically build a new Italian expressive and emotive talking head capable of believable and emotional behavior. The methodology, the procedures and the specific software tools utilized for this scope will be described together with some implementation examples.
