Modifications of the Speech Articulatory Characteristics in the Emotive Speech

The aim of the research is the phonetic articulatory description of emotive speech achievable studying the labial movements, which are the product of the compliance with both the phonetic-phonological constraints and the lip configuration required for the visual encoding of emotions. In this research we analyse the interaction between labial configurations, peculiar to six emotions (anger, disgust, joy, fear, surprise and sadness), and the articulatory lip movements defined by phonetic-phonological rules, specific to the vowel /'a/ and consonants /b/ and /v/
