Emotion Generation using LPC Synthesis

Abstract

S speech synthesis means artificial production of human speech . A system used for this purpose is called a speech synthesizer . The most important qualities of a speech synthesis system are naturalness and intelligibility . Naturalness describes how closely the output sounds like human speech, while intelligibility is the ease with which the ou tput is understood. Emotion is an important element in expressive speech synthesis. T his paper describes LPC analysis and synthesis technique . The LPC s are analyse d for each speech segmen t and pitch p eriod is detected . At synthesis the speech samples equal to the samples in one pitch period are reconstructed using LPC inverse synthesis. Thus by using LPC Synthesis we can implement pitch modification or duration modification or spectrum modification to introduce emotion in the neutral speech, such as happiness or anger.
