Seminar at Speech, Music and Hearing:

X-job seminar:

An interactive articulation-to-area-function phonetics modelling tool

Mátyás Jani

Opponent: Anton Hedblad

Abstract

APEX is the name of a ongoing research project in phonetics conducted by Lindblom, Sundberg, Ericsdotter and others, in which vocal tract shapes are related to formant frequencies in great detail. The main objectives of this work were to rewrite and modernize the software platform of APEX, and at the same time to explore the feasibility of using the SuperCollider (SC) development environment as an interactive platform for voice modelling. SC has an interpreting language and a client-server architecture which differ somewhat from traditional in-process programming. It was found that real-time simulation with area-function and formant frequency calculation in SC is possible, but only if the code is carefully optimized and structured. The resulting software inherits the portability of SC, and the modular architecture makes it easy to change part of the software, for example to implement alternative synthesis engines. Suggestions are made for an improved architecture and how the project would benefit from a 3D model.
