  • A wave equation model for vowels: Measurements for validation

    This thesis presents a procedure for simultaneous recording of anatomic and acoustic data on speech production. The thesis also presents a mathematical model of vowel production and its pilot implementation as frequency domain numerical simulator. The model is based on the wave equation. The anatomic data is recorded with MRI and the acoustic data with a purpose built, MRI compatible sound recording setup. Both modalities of the data will be used in building the next generation of the simulator, estimating its parameters, and validating it. Compared with previous contributions in this area, the acoustic and anatomic data are more closely matched and, hence, the procedure more informative. The main scientific contribution is the description of the sound recording arrangement as well as the guidelines and considerations detailed for simultaneous data acquisition in MRI.
