Applications: 1. The invention discloses a speech recognition system that recognizes words spoken by users in any language or in any combination of languages with high accuracy upon being presented with this invention, the word having been spoken by the same users in the same ambient environment. 2. The speech recognition system transforms input sound files into a sparse, distributed representation using neural networks intended to mimic the representational capacity of the human pre-frontal cortex. 3. The sparsity of the representation in the transformed space permits accurate recognition of individual word tokens using machine learning methods, independent of the language used, the speakers accent or prevailing noise conditions.
Advantages: 1. The present subject matter described herein, in general relates to a speech recognition system and particularly to neural network system for speech recognition. More particularly, the present invention relates to a language agnostic, limited vocabulary speech recognition system. 2. An object of the present invention is to provide an accurate speech recognition system that overcomes the drawbacks of the prior art. 3. Another object of the present invention is to provide a speech recognition system that is not dependent large corpora for training the system. 4. Yet another object of the present invention is to provide a speech recognition system that reduces the amount of data to recognize speech sounds.

I-Mitra(आई-मित्र) Welcomes You..
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
