MODIFIED SYNTHESIS STRATEGY FOR VOWELS AND SEMI VOWELS (KLATT SYNTHESIZER)

Klatt synthesizers are one of the most widely used formant synthesizers. Klatt synthesizers are usually implemented either with fixed parameter update rate or with variable parameter update rate. This paper proposes new method to store control parameters and parameter update strategy to improve the naturalness of the synthesized vowel and semi vowel sounds.
