Abstract
Objectives: This paper presents a modified method of diphone synthesis of Kazakh language. The aim of this work is to create a high-speed synthesizer with acceptable quality. Methods/Statistical Analysis: Diphones represent transitions between sounds (interphoneme transitions). Therefore, to increase the quality of standard method, a technique was used for trimming the edges according to signal quasi-periods and automatic splicing normalization according to the amplitude at the beginning and the ends, which gave a significant increase in quality while maintaining the advantages of this method of synthesis. Application/Improvements: Finally, the described method is implemented as software for speech synthesis of the Kazakh and Russian languages. Keywords: Diphone, Quasi-Period, Phoneme, Synthesis, Speech
