Text to speech using java

ABSTARCT :

Speech is one of the oldest and most natural means of information exchange between human. Over the years, Attempts have been made to develop vocally interactive computers to realise voice/speech synthesis. Obviously such an interface would yield great benefits. In this case a computer can synthesize text and give out a speech. Text-To-Speech Synthesis is a Technology that provides a means of converting written text from a descriptive form to a spoken language that is easily understandable by the end user (Basically in English Language). It runs on JAVA platform, and the methodology used was Object Oriented Analysis and Development Methodology; while Expert System was incorporated for the internal operations of the program. This design will be geared towards providing a one-way communication interface whereby the computer communicates with the user by reading out textual document for the purpose of quick assimilation and reading development.

EXISTING SYSTEM :

? Text to speech synthesis is a rapidly growing aspect of computer technology and is increasingly playing a more important role in the way we interact with the system and interfaces across a variety of platforms. ? We have identified the various operations and processes involved in text to speech synthesis. ? However, maximum naturalness typically require unitselection speech databases to be very large, in some systems ranging into the gigabytes of recorded data, representing dozens of hours of speech. ? Also, unit selection algorithms have been known to select segments from a place that results in less than ideal synthesis (e.g. minor words become unclear) even when a better choice exists in the database.

DISADVANTAGE :

? It is expected that the new system will reduce and improve on the problems encountered in the old system. ? This source of the knowledge includes domain specific facts and heuristics useful for solving problems in the domain. ? This rule interpreter inference engine applies to the knowledge base information for solving the problem. ? The speech synthesizer will be very useful to any researcher who may wish to venture into the “Impact of using Computer speech program for brain enhancement and assimilation process in human beings”.

PROPOSED SYSTEM :

• In this paper we propose an enhancement of a Java FreeTTS speech synthesizer by adding the function of spatial positioning of both the speaker and the listener. • In this paper, we propose an extension to the FreeTTS software that enables the text to speech conversion in a 3D audio environment. • Several researchers proposed different and more advanced auditory versions of web browsers. • We propose some innovative ideas for the practical use of such a system and we already give some preliminary results and user feedback.

ADVANTAGE :

? Expert system was used in the internal operations of the program, following the algorithm of RuleBased computation. ? The speech engine used in this new system was the FreeTTS speech engine. FreeTTS was used because it is programmed using JAVA (the backbone programming language of this designed TTS system). ? This is a java specification mark-up language used to annotate spoken output to the preferred construct of the user. ? While the basic functions of both speech synthesis and speech recognition takes only minutes to understand, there are subtle and powerful capabilities provided by computerized speech that developers will want to understand and utilize.
