Borno: A Bengali Voice Command Based Interaction System

Abstract

We are introducing you “Borno”, a Bengali Voice Command Based Interaction System for the personal computer. The system uses the Speech Application Program Interface (SAPI) to recognize the speech. We have developed our own grammar in order to map the Bengali phonemes in English representation. We have also developed an algorithm to reduce the confusion of the machine in recognizing the same type of phonetics in the language. The algorithm will also help to understand the Bengali command with more accuracy. Another thing of this system is that we have used Microsoft speech synthesizer to synthesize the speech in Bengali also. It helps to implement humancomputer interaction in a wide range. This feature will help the disabled people especially the blind people who are unable to read the text on the computer. This system can be widely used among the Bengali speaker around the world. This system can also be used in rural areas of Bangladesh. Most of the people of Bangladesh are illiterate. That’s why they face challenges while operating a computer in English. In order to use a computer and get the facilities of modern technology, they have to get the training. So, we think instead of using traditional mouse and keyboard if they are able to operate the computer with their own voice command in their native language, it will help them a lot to get the facilities of the computer. So, we design this system to help them in this regard. We achieve 90% of accuracy in the noise-free environment and 76% of accuracy in the noisy environment with the help of 20 individual candidates both male and female. Our goal is to raise the accuracy of the system in the future.
