    Voice search is the technology underlying many spoken dialog systems (SDSs) that provide users with the information they request with a spoken query. The information normally exists in a large database, and the query has to be compared with a field in the database to obtain the relevant information. The contents of the field, such as business or product names, are often unstructured text. This art... View full abstract»

    Semantics deals with the organization of meanings and the relations between sensory signs or symbols and what they denote or mean. Computational semantics performs a conceptualization of the world using computational processes for composing a meaning representation structure from available signs and their features present, for example, in words and sentences. Spoken language understanding (SLU) is... View full abstract»

    Progress in both speech and language processing has spurred efforts to support applications that rely on spoken rather than written language input. A key challenge in moving from text-based documents to such spoken documents is that spoken language lacks explicit punctuation and formatting, which can be crucial for good performance. This article describes different levels of speech segmentation, a... View full abstract»

    Spoken language translation (SLT) is of great relevance in our increasingly globalized world, both from a social and economic point of view. It is one of the major challenges in automatic speech recognition (ASR) and machine translation (MT), driving an intense research activity in these areas. Speech translation is useful to assist person-to-person communication in limited domains like tourism an... View full abstract»

    In this article, the essential process of auditory perception and advocated for the integration of structural and functional knowledge of the auditory system is reviewed. A perspective, called the constructionist's paradigm, is suggested which looks at the neuron-anatomical structure for auditory perception in three essential stages with intermediate signal representations that allow interchangeab...

    Spatial audio is a field that investigates techniques to reproduce spatial attributes of sound (e.g., direction, distance, width of sound sources, and room envelopment) to the listener. Such attributes cannot be reproduced accurately with one loudspeaker, therefore two-channel stereophony was introduced, later extended to different surround formats having five to eight loudspeakers. An even more a... View full abstract»

    In this lecture note we discuss methods to improve the accuracy of unbiased estimators used in many signal processing problems. Our approach is based on introducing a bias as a means of reducing the mean-squared error (MSE). The important aspect of our framework is that the reduction in MSE is guaranteed for all values of the unknown parameter. View full abstract»
