Implementation of PSOLA for Comparative Linguistic Analysis of English and Marathi Language

Abstract: Naturalness is one of the very important parameter to evaluate the speech synthesis system. Besides other prosodic feature parameters like pitch, formant and energy, pitch plays a very significant role in understanding spoken signals. To obtain naturalness in synthesized speech, pitch has to be analysed. Pitch is dependent on language we attempted to present the implementation of PSOLA algorithm on the database of English and Marathi sentences. It is seen that English being irregular language results in different accent whereas Marathi being regular proves to be with good synthesized speech.

Keywords: Speech Synthesis, PSOLA, pitch.
