SPEECH SYNTHESIS

SUBMITTED BY AAYUSHEE GUPTA MONALIKA BISWAS ANTARIKA BARUAH

OBJECTIVE SPEECH SYNTHESIS : Artificial production of human speech.  SPEECH SYNTHESIZER: Computer system used for speech synthesis and can be implemented in software and hardware.  OUR OBJECTIVE : To primarily use MATLAB or Java for developing the Text-to-Speech software and implement it in an application like a talking dictionary or any other application for educational purpose 

SCOPE 

APPLICATIONS



Screen readers for people with visual impairment People with Dyslexia Educating pre-literate children People with severe verbal impairment In combination with Speech Recognition

PROCESS DESCRIPTION

A

text-to-speech system (or "engine") is composed of two parts: a front-end and a back-end  FRONT-END  text normalization, pre-processing, or tokenization  text-to-phoneme or grapheme-to-phoneme conversion.  BACK-END  converts the symbolic linguistic representation into sound

IMPLEMENTATION TOOLS 

MATLAB VOICEBOX TOOLBOX



Toolbox comprising of MATLAB routines Functions for speech synthesis include: Sapisynth: Text-to-speech synthesis (TTS) of a string or matrix entries Glotros: Calculates the Rosenberg model of the glottal flow waveform Glotlf: Calculates the Liljencrants-Fant model of the glottal flow waveform

JSAPI: javax.speech.synthesis



‘javax.speech.synthesis’ package defines the Synthesizer interface to speech synthesis





Includes a set of ing classes and interfaces. Functionality of a Synthesizer is inherited from the Engine interface in the javax.speech package.
