Comparative Analysis of Speech Synthesis Techniques and Speech Database

Abstract

Speech technology relates to the technologies designed to duplicate and respond to the human
voices. It provides human communication with machine. Speech synthesis is one of the major
components under this technology. It involves conversion of text to speech using various
modules. For decent communication - speech must be clear and intelligible for the purpose of
the communication to be accomplished. To generate natural sounding speech it is pre requites
to imitate the dynamic human voice. This is a complex undertaking, requiring researchers to
incorporate all parameters of human voice in synthesized speech. Imitation of the dynamic
human voice is required to generate this. The objective of this work is to present comparative
analysis of various speech synthesis technique with various parameters. This will include
some of the well known techniques used in speech synthesis system for last two centuries. It
also explore the state of art of speech synthesis, useful available TTS, speech databases and
challenges which are at the forefront of this exciting and challenging field.
