Recent Trends in Text to Speech Synthesis of Indian Languages

A Text To Speech (TTS) synthesizer is a computer application capable of converting arbitrary input text into speech. This conversion broadly involves two steps, namely, text processing and speech synthesis. Text processing converts the entered text to a sequence of synthesis units, while speech synthesis is the generation of an acoustic wave form corresponding to each of these units. Naturalness and intelligibility are the most important qualities expected from a TTS system. In this paper we aim to provide an overview of various techniques for text to speech synthesis, discuss their characteristics, summarize and compares advantages and drawbacks. We have listed various Text-to-Speech synthesis frameworks developed and implemented at different Indian institutes.
