Making the Tongue Model Talk: Merging MRI & EMA Measurements

Olov Engwall

KTH, Sweden

Electromagnetic articulography (EMA) data collected with the Movetrack measurement system has been used to set the parameter values in a three-dimensional tongue model dynamically. The outputs from four of the receiver coils are used in the parameter control; the data from the coil on the lower incisor for the jaw height parameter and the three coils on the tongue, T1-T3, for the parameters of different parts of the tongue. The measurements of T1 control the raising and advancing of the tongue tip, those of T2 the tongue body and those of T3 the tongue dorsum movement. Rules to replicate the measured control sequences synthetically have been developed and the synthetic control sequences have been used to synthesize new fricative-vowel sequences.
