A 12-week program was developed in which electrical engineering concepts, in form of robotics projects, are taught to students at a secondary educational institution for the deaf and hearing impaired. The robotics course was originally designed for, and has been taught for about a decade to freshmen at the Temple University college of Engineering. The objectives of this project range from eliminating existing boundaries of engineering education to increasing the anticipation of success amongst the physically impaired. A prior breakthrough in the extension of engineering education beyond assumed “limits” was achieved when a young man who was both sight and …

Recognizing speakers from their voices is a challenging area of research with several practical applications. Presently speaker verification (SV) systems achieve a high level of accuracy under ideal conditions such as, when there is ample data to build speaker models and when speaker verification is performed in the presence of little or no interference. In general, these systems assume that the features extracted from the data follow a particular parametric probability density function (pdf), i.e., Gaussian or a mixture of Gaussians; where a form of the pdf is imposed on the speech data rather than determining the underlying structure of …

Two speaker indexing system for conversations are presented in this paper. The first method involves indexing two-speaker conversations. In this method, two reference models are judiciously chosen from the conversation such that they represent the two different speakers. Models are then matched to the reference speakers using distance-based comparisons. The second technique is based on first determining the number of participants in the conversation using a speaker count method termed the “Residual Ratio Algorithm” (RRA), and then indexing based on this count. The RRA involves an elimination process in which speech segments matching a chosen set of reference models are …
