摘要：
We report the design and development of Thirukkural, the first text-to-speech converter in Tamil. Syllables of different lengths have been selected as units since Tamil is a syllabic language. Automatic segmentation algorithm [8] has been devised for segmenting syllables into consonant and vowel. The units are pitch marked using Discrete Cosine Transform - Spectral Auto-correlation Function (DCT-SAF) [6]. Prosodic information is captured in tables based on extensive observation of spoken Tamil. During synthesis, DCT based pitch modification [3][7][11] is applied for both waveform interpolation and modifying pitch contour for different sentence modalities. Thirukkural is designed in VC++ and runs on windows 95/98/NT. Perceptual evaluation by natives show that the synthesized speech is intelligible and fairly natural.
