Pattern recognition has been demanding field from many years. We are also discuss driving force behind its swift development, that is pattern recognition is used to give human recognition intelligence to machine which is soul of today's many modern application. It acts as wheel of many techniques and applications in different fields. Pattern Recognition is recognition process which recognizes a pattern using a machine or computer. It is a study of ideas and algorithms that provide computers with a perceptual capability to put abstract objects, or patterns into categories in a simple and reliable way. The development and demand of pattern recognition technology is very fast and applications of pattern recognition are increase day by day. To fulfill this need, more and more researchers and scientists are evolved new pattern recognition techniques and apply them to many real life applications such as agriculture, robotics, biometrics, medical diagnosis, life form analysis, image processing, process control, information management systems, aerial photo interpretation, weather prediction, sensing of life on remote planets, behavior analysis, , Speech recognition, automatic diseases detection system in the infected plants, cancer detection system etc. with combination of other technology. Particular, in image retrieval system, pattern recognition play important for improving accuracy of image retrieval by using variety of recent techniques and their combination.","PeriodicalId":347883,"journal":{"name":"2014 International Conference on Communication and Network Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128785188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The parameter vectors are assumed to be the constituents of the speech signal over a specified duration during which it is stationary. Typical representations are Mel Frequency Cepstral Coefficients, Linear Prediction Coefficients etc. The process of isolated word recognition involves the mapping of these parameters with speech but it cannot because there are large variations in the realized speech waveform due to speaker variability, modulation, context, etc. The parametric speech vectors corresponding to each vector is modeled using Gaussian Mixture Model and its distribution is observed. The Expectation Maximisation algorithm is used in the Radial Basis Function network to best fit the test vector. The gradient descent algorithm applied on Radial Basis Function Neural Network is proposed to approximate the functions which have high non-linear order. The learning rates of the network are made proportional to the probability densities obtained from the Gaussian Mixture Model. Isolated words of esophageal speech appear to be recognized better in this method compared to previous methods since it consists of non linear components.","PeriodicalId":347883,"journal":{"name":"2014 International Conference on Communication and Network Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129604814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MFCC has been identified as an efficient feature for identifying the speaker because it extracts speaker specific information. The performance of even best speaker identification system with MFCC feature degrades in uncontrolled communication environment. RASTA processing of speech improves the performance of identification system even in the presence of convolutional and additive noise. This paper combines the best of these two processes to yield RASTA-MFCC feature which is robust to noise and also contributes speaker dependent information to identify the speaker efficiently. GMM-UBM (Gaussian Mixture Model-Universal Background Model) modeling technique is used for its faster training and relatively easier updating of new speakers. Experimental result of 93.2% accuracy for Triangular filter bank and 94.5% accuracy for Gaussian filter bank are obtained for 50 speakers of MEPCO speech database in presence of additive and convolutive noise in the context of voice based students' attendance entry.","PeriodicalId":347883,"journal":{"name":"2014 International Conference on Communication and Network Technologies","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127761461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, low leakage 1bit full adder cells are proposed for mobile applications with low ground bounce noise and a novel technique has been introduced with improved staggered phase damping technique for further reduction in the peak of ground bounce noise. Noise immunity has been carefully considered since the significant threshold current of the low threshold voltage transition becomes more susceptible to noise. We introduced a new transistor resizing approach for 1bit full adder cells to determine the optimal sleep transistor size which reduce the leakage power and ground bounce noise. The simulation results depicts that the proposed design also leads to efficient 1bit full adder cells in terms of standby leakage power, active power, ground bounce noise and noise margin. We have performed simulations using Cadence Spectre 90nm standard CMOS technology at room temperature with supply voltage of 1V.","PeriodicalId":347883,"journal":{"name":"2014 International Conference on Communication and Network Technologies","volume":"239 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124622896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
