Developing Intonation Pattern for Tamil Text To Speech Synthesis System

K.C.Rajeswari, G. Karthick Prabu

The demands of interactive approaches to TTS require more freedom to express prosody than current systems allow. Most current TTS systems, including the Bell Labs TTS system, were designed to operate on text with little or no ‘‘mark-up’’ information beyond the text. The prosody subsystem was therefore designed conservatively. The application may be ‘‘intending’’ to convey that a set of words is a single proper noun, that a word is especially important, or that a word needs confirmation. This state information needs to be expressed prosodically, so one should think of speech synthesis more in the context of a concept-to-speech system than a text to- speech system. Similarly, there are applications where the simulation of emotions, subtle meanings in speech acts, and stylistic variations are desirable.
