Klatt Synthesizer in Simulink

by Sean McLennan

April, 2000




Introduction

This paper outlines the construction and use of a speech synthesizer based on Klatt (1980) that was implemented in The MathWorks Incís Simulink® environment which operates in conjunction with MATLAB®. Two aspects of the model are described: the model itself and the manipulation of the model by a function that translates pseudo-phonological coding into time-indexed parameter values to be used by the model in synthesizing particular utterances.
