The speech synthesis system is an artificial production of speech with the help of speech synthesizers.It can be achieved using various techniques.During synthesis the smoothing of concatenating points is an important aspect to be studied.This paper attempts to find the effect of pitchmarking process using Time Domain-Pitch Synchronous Overlap and Add (TD-PSOLA) method.The database consists of 60 sentences containing various phones, syllables, phrases which provide prosodic effects in male and female voices.The analysis shows that the pitch -marking process affects the quality of speech in the synthesis process which soothes at concatenation point.
