Ultrasound analysis of the lingual gestures in Hungarian speech

Abstract

Tamás Gábor Csapó, as one of the founding members of MTA–ELTE “Lendület” Lingual Articulation Research Group, introduced the technique of ultrasound tongue imaging (UTI) into articulatory research in Hungary. He mastered this technique during a Fulbright Scholarship at Indiana University, Bloomington. He did pioneering work in development of UTI data analysis methodology, silent speech interfaces, and other digital applications of UTI. His achievements are acknowledged and his work is referenced world-wide. In the present paper, after a brief outline of the technique of 2D ultrasound tongue imaging, we review the research and application areas in which Tamás Gábor Csapó made his marks within the fields of articulatory research and articulatory-to-acoustic conversion.
