Acoustic signal of speech sounds is underlain by aerodynamic principles. The Aerodynamics of speech contributes to the mechanistic explanations of speech production. This database was designed during an ARC project ”Dynamique des syste`mes phonologiques” in which the study of aerodynamic constraints on speech was an important target. Data were recorded between 1996 and 1999 at the Erasmus Hospital (Hôpital Erasme) of Université Libre de Bruxelles. The goal was to obtain a substantial amount of data with simultaneous recording, in various context, of the speech acoustic signal, subglottal pressure (Ps), intraoral pressure (Po), oral airflow (Qo) and nasal airflow (Qn). This database contains recordings of 2 English, 1 Amharic, and 7 French speakers and is provided with data conversion and visualisation tools. Another aim of this project was to obtain some reference values of the aerodynamics of speech production for female and male speakers uttering different types of segments and sentences in French.
