We aim to develop an automated system to assess oral reading skills of primary school children (learning English as a second language) that could eventually be valuable in the scenario of teacher shortage typical of rural areas in the country. This work focuses on the rating of prosody, an important aspect of fluency in speech delivery. In particular, a system for the detection of word prominence based on prosodic features is presented and tested on real-world data marked by background noise typical of the school setting. To counteract the observed drop in prominence classification accuracy, two distinct approaches to noisy speech enhancement are evaluated for various types of background noise. A recently proposed Generative Adversarial Network(GAN) based method is found to be effective in achieving noise suppression with low levels of speech distortion that minimally impact prosodic feature extraction. The implementation and training of the GAN system is discussed and insights are provided on its performance with reference to that of classical spectral subtraction based enhancement.","PeriodicalId":121544,"journal":{"name":"2018 Twenty Fourth National Conference on Communications (NCC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133842829","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 the current work, we propose offline routing and spectrum assignment (RSA) schemes in view of the transfer of deadline complying voluminous data demands in elastic optical networks. The proposed schemes, which jointly optimize time and frequency domains, are initially formulated as an integer linear program (ILP). Subsequently, in view of practicality, we propose scalable scheduling techniques which combine three methods of ordering demands, and two schemes of RSA. To evaluate the proposed ILP model and the scheduling methods, we conduct simulations considering realistic network parameters and topologies. The obtained results demonstrate that in comparison to ILP model, scalable methods obtain similar spectrum usage performance within reasonable times. Lastly, based on the results, we also provide a ‘rule-of-thumb’ on the selection of appropriate scheduling technique.","PeriodicalId":121544,"journal":{"name":"2018 Twenty Fourth National Conference on Communications (NCC)","volume":"429 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122135057","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}

However, the inverse problem is ill-posed, nonlinear, and unstable due to diffusive nature of optical photons through the biological tissue. The conventional DOT imaging methods require the forward problem to be solved repeatedly at each iteration which makes it computationally expensive. Recently, the theory of compressive sensing (CS) has been used in DOT and provided significant reconstruction of sparse objects in many DOT imaging problems. The main objective of this paper is to solve the DOT inverse problem using MMV (multiple measurement vectors) based CS framework and the sparse recovery algorithm like CS-MUSIC (multiple signal classification) is studied. The experimental validation of the CS-MUSIC has been done on a paraffin wax rectangular sample through a DOT experimental set up. We also studied the conventional DOT imaging method like least square method in this paper. The performance metric mean square error (MSE) is used to evaluate the performance of the reconstruction in DOT imaging. Simulation results showed that the CS-MUSIC algorithm outperforms the conventional DOT imaging method in DOT imaging. The advantage of this study is that the forward problem need not be solved repeatedly which are inherent in conventional DOT.","PeriodicalId":121544,"journal":{"name":"2018 Twenty Fourth National Conference on Communications (NCC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121195252","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}
