This paper presents new temporal information regarding the production of European Portuguese (EP) nasal vowels, based on new EMMA data. The influence of speech rate on duration of velum gestures and their coordination with consonantic and glottal gestures were analyzed. As information on relative speed of articulators is scarce, the parameter stiffness for the nasal gestures was also calculated and analyzed. Results show clear effects of speech rate on temporal characteristics of EP nasal vowels. Speech rate reduces the duration of velum gestures, increases the stiffness and inter-gestural overlap.
