This paper explores the modeling of prosody parameters for improving naturalness of Tamil speech synthesis, by studying recorded utterances of speech with and without explicit emotions. To begin with, we look at interrogative and exclamatory Tamil sentences. Prosody parameters namely, pitch contour, energy and duration of each word in the sentences were observed, analyzed and generalized from the un‐intonated and intonated, interrogative and exclamatory human speech. Differences in energy level were also analyzed between the two sets of utterances in three different frequency bands. Pitch is by modified in the LP residual domain using DCT. Energy is modified by multiplying the signal by the hypothesized factor and duration is modified as per the duration model by duplicating or removing integer number of pitch periods as necessary. The model was implemented on speech synthesized from Thirukkural TTS, developed by MILE LAB, and the results were found to be satisfactory.
