dc.description.abstract

Articulatory speech synthesis provides an alternative to the state of the art concatenative and formant systems, holding potential for more versatile and expressive arti cial speech due to its physical modelling basis. However, a major limitation of practical articulatory synthesis is gaining adequate control of the complex underlying physical models, which stems from a lack of articulatory data. In an e ort to procure more data, a Genetic Algorithm approach to Acoustic-Articulatory Parameter Inversion is taken. is paper presents the initial results from testing a number of tness functions for the Acoustic-Articulatory Parameter Inversion of three vowels, /a/, /o/, and /e/. ree feature vector representations of the vowels were tested; Hertz, Mel–scale, and Cents, in conjunction with three distance metrics. e distance metrics de ned the tness score by calculating the similarity between a candidate and targets feature vector. A Voiced/Un–Voiced constraint was also added as a penalty function, and an indicator of loudness was implemented using a Root Mean Square based co-e cient. e results indicated that certain combinations of the above could lead to convergence towards all three vowels. However, the quality of convergence was not uniform.
