Abstract. In this study the gesture duration and articulator velocity in consonant-vowel-transitions has been analysed using electromagnetic articulography (EMA). The receiver coils where placed on the tongue, lips and teeth. We found onset and offset durations which are statistically significant for a special articulator. The duration of the offset is affected by the degree of opening of the following vowel. The acquired data is intended to tune the control model of an articulatory speech synthesizer to improve the acoustic quality of plosivevowel-transitions.
