With the development of technology, software is becoming critical for the success of many large systems. There are many risks involved in creating high quality software on time and within budget. The success of software product, both functionally and financially is directly related to the quality of the requirements. Software requirement risk addresses the possibility of suffering a loss of any functional or non-functional requirement of the system. It refers to the uncertainties caused by differences between the requirements perceived by developers and user groups' expectation of the system....

This is all about a successfully implemented research project which is expected to be a commercial product in future. Objective of the research is to develop an Automatic Isolated Speech Recognition System (AISR) which will be able to classify four distinct words class enunciated as "GO", "STOP", "LEFT" and "RIGHT". Speech data are analyzed mainly with Mel Frequency Cepstrum Coefficients (MFCC) analysis along with some subsidiary DSP processing to create compact and prolific speech database. While Artificial Neural Network (ANN) is used as a classifier or recognizer to classify among...
