New technologies for simoultaneous acquisition of speech articulatory data: ultrasound, 3D articulograph and electroglottograph

The study of articulatory features in speech requires highly sophisticated instruments. Most of them are available at the CRIL research centre (Centro di Ricerca Interdisciplinare sul Linguaggio – University of Salento – Lecce) where the equipment usually found for articulatory studies in the most advanced international research centres is accessible: 3D articulograph, ultrasound system, electroglottograph, electropalatograph, and aerophone. Some of these instruments have been synchronized within the European CONTACT project, and have already been used for simultaneous recording. In this paper, we will point out the peculiarity of each instrument, the added information related to the simultaneous recording, and the main steps towards their complete fruition in the specific phonetic-phonology field. In order to do that, we will briefly describe the recording set up and the first data collection, we will focus on a subset of the recordings in order to provide examples of the achieved articulatoryphonetic information, and describe the work-in-progress software analysis environment we use for linguistic purposes.
