What is New?

My web-site has been listed on the DMOZ Project Under the category Computers > Speech Technology > Research. DMOZ, The Open Directory Project is the largest, most comprehensive human-edited directory of the Web. It is constructed and maintained by a vast, global community of volunteer editors. There are currently (30'th October 2006 at 4:51 PM EST) about 56 websites listed under this category.

Primary Research Interest(s)

   1. "Cognitively Inspired Speech Recognition (CISR) - I would like to observe the human speech recognition system, to solve the pertinent problem of inaccuracy in current speech recognition/ synthesis algorithms".
   2. "SOS - Speech Operating System - My yet another research interest is to work to develop a Speech based Operating System (SOS) where Speech would be the primary Input/ Output Interface".
   3. "Artificial Neural Computing Device (ANCD) - To realize an artificial neuron using electronic components and then extend this neuron to perform computational operations - To realize a machine completely based out of Artificial Cognition"

Secondary Research Interest(s)

   1. "Material Science based solution to the processor heat problem - To figure out ways to maintain processors and other GPU's well within their operating temperature. To figure out such ways so as to enable efficient operation of the processors and avoiding any glitches due to over heating of the chip".
   2. "Biologically inspired memory device - Understand the human memory organization and try to replicate the same on physical hardware medium for better efficiency and performance on data disks"
   3. "Hexadecimal storage device - or the likes - crapping off the conventional binary storage technique".

Current research work at UB

1. "Building Speech Capabilities into Virtual Reality Agents - As applicable to Agents in Virtual Reality Drama. Working under the guidance of Dr. Shapiro and Prof. Josephine Anstey. As a part of this effort, I'm working with the VR Drama group here, particularly on "The trail the Trial" project, to build speech understanding and synthesis capabilities into the Virtual Reality agents in the drama.

Refereed Papers

Topic:     "Speech interfaces for local dialects"
Keywords: Speech recognition, Computer literacy, local dialects, speech pattern
                   recognition, voice command interpreter.
Authors:      Mr. S.S.Sridhar, Asst Professor, K.Vishwac Sena, N.Madhumitha,
                   Dept of Computer Science Engineering, S.R.M Engineering College.
Abstract:     "Any rural society can be said to have achieved a state of true
                   and complete upliftment only if its literacy rate is improved and is
                   in par with the urban society" - This statement really beckoned
                   us to research on a technique to improve the standard of the
                   rural society. "Advanced Voice activaTOR - AVATOR" is a voice
                   recognition system, which can recognize a voice pattern in any
                   language, provided the database of phonemes for that particular
                   language is provided. (more ...)

Non-Refereed Papers

Keywords:   Operating System, Speech recognition, future of speech
                   recognition, Speech OS.
Authors:      K.Vishwac Sena
Abstract:     (work in progress)                                                                                                                                     Top

Topic:      "Artificial neural computing device, a CTD based approach"
Keywords:   CTD Neuron, Neural computing device, Hexa-Grid structure,
                   'Neuron', 'artificial neuron'.
Authors:      K.Vishwac Sena, N.Madhumitha, S.G.Karthik
Abstract:     Constructing an artificial neuron using electronic components
                   like capacitors, Transistors and diodes. The paper was further
                   extended to propose a method to realize the operations (basic)
                   of any computing device using an artificial neural network grid.
                   We propose a new Capacitance-Transistor-Diode Logic, which
                   will be used to realize a 'Neuron' and hence the NN Board
                   This paper covers in detail the steps involved in constructing
                   the artificial neuron, with thorough analysis on the difficulties
                   in realizing such a network. We have also worked to present
                   the design (reusable and the eagle nose structure) to construct
                   "Basic units of computation - AND, OR, NOT, NAND, D Flip-flop,
                   Shifters & multiplexers" (more ...)

Topic:      "Advanced voice activator for windows"
Note:            This one is pretty much similar to the paper on "speech
                        interfaces for local dialects", the only difference being that
                   this paper concentrated more on the design,
                   implementation & implications of realizing a system
                   proposed in the earlier paper.
Keywords:   AVATOR, speech recognition system - windows, language
                       independent speech recognition, phoneme mapping.
Authors:      K.Vishwac Sena, N.Madhumitha
Abstract:     People all around the world have narrowed down their
                   perspective of thinking to just complex syntax, in order to use
                   the computers to its maximum efficiency. As a result, the common
                   man is kept ignorant of the vast world of computer. We aim to
                   overcome this drawback by developing a voice interface whereby
                   even a layman can talk to a computer and get a job done. By
                   designing a Voice Recognition System we plan to scale new
                   heights in Human Interface Development. The system we propose
                   would be language independent, provided the database of
                   phonemes for that particular language is installed. (more ...)

Topic:      "Processor-Heat Problem - Material science based solution"
Keywords:   Differential equations, scientific applications - differential
                   equations, microprocessors, IC fabrication, "Processor - heat
                   problem", Heat-Radiation-Manipulation.
Authors:      N.Manasa, R.Sriranjani, K.Vishwac sena
Abstract:     Overheating of the processors, has been one of the major
                   problems which the computer hardware industry is facing
                   of late. This paper proposes a solution to this problem, in a
                   distinctive approach, by solving the "Heat-absorption-radiation"
                   differential equation. Traditional cooling strategies either required
                   the computer to be placed in a well ventilated (preferably air
                   conditioned) environment. We propose an alternate cooling
                   mechanism to keep the computer and the processor, cooler.
                   This study has unwound a totally new perspective to the problem,
                   and a distinctive well bred solution - "To coat the inner side of
                   the processor and the CPU using a special heat absorbing
                   material" (more ...)
