Voice control system

Abstract

This project describes a software-based system for communication and control by disabled people based on automatic recognition of phonemes. This program allows users to navigate around an alphabet board by making phonemic utterances, thus enabling the user to spell out messages. Phoneme recognition provides an alternative to speech recognition technologies for people who have lost the ability to speak (often due to a stroke, accident or other disabling condition) but remain capable of producing simple repeatable utterances. Voice Control system (VCS) aims at developing a voice-controlled tool for operating computer targeting physically handicapped and blind users having difficulties using a standard keyboard and mouse. Our voice controlled system which addresses this situation by presenting an interface which allows a user to activate any web page element through visual enumeration (Indexing) by an appropriate command. Through an implementation of a user centric incremental search algorithm, elements are matched according to user expectation as characters are entered into the interface. Using the user’s browsing history; we improve the efficiency of the selection process and find potentially interesting page links for the user within the current web page. The foremost objective of this project is to give an ease to the special citizens in using computer. Secondly we want to deploy our product in a school of special students so that we can practically examine the outcomes of the product, its usability and user’s response. VCS designs to operate in the schools of disabled students and they will allow them to control the computer through voice. All the applications are controlled through voice including activities such as opening, closing, typing... Etc. Indexing technique is used to make communication with computer through voice easier.
