A complete overview of distant automatic speech recognition The performance of conventional Automatic Speech Recognition (ASR) systems degrades dramatically as soon as the microphone is moved away from the mouth of the speaker. This is due to a broad variety of effects such as background noise, overlapping speech from other speakers, and reverberation. While traditional ASR systems underperform for speech captured with far-field sensors, there are a number of novel techniques within the recognition system as well as techniques developed in other areas of signal processing that can mitigate the deleterious effects of noise and reverberation, as well as separating speech from overlapping speakers. Distant Speech Recognitionpresents a contemporary and comprehensive description of both theoretic abstraction and practical issues inherent in the distant ASR problem. Key Features: Covers the entire topic of distant ASR and offers practical solutions to overcome the problems related to it Provides documentation and sample scripts to enable readers to construct state-of-the-art distant speech recognition systems Gives relevant background information in acoustics and filter techniques, Explains the extraction and enhancement of classification relevant speech features Describes maximum likelihood as well as discriminative parameter estimation, and maximum likelihood normalization techniques Discusses the use of multi-microphone configurations for speaker tracking and channel combination Presents several applications of the methods and technologies described in this book Accompanying website with open source software and tools to construct state-of-the-art distant speech recognition systems This reference will be an invaluable resource for researchers, developers, engineers and other professionals, as well as advanced students in speech technology, signal processing, acoustics, statistics and artificial intelligence fields.

Love and family life in the global age: grandparents in Salonika and their grandson in London speak together every evening via Skype. A U.S. citizen and her Swiss husband fret over large telephone bills and high travel costs. A European couple can finally have a baby with the help of an Indian surrogate mother. In their new book, Ulrich Beck and Elisabeth Beck-Gernsheim investigate all types of long-distance relationships, marriages and families that stretch across countries, continents and cultures. These long-distance relationships comprise so many different forms of what they call ‘world families’, by which they mean love and intimate relationships between individuals living in, or coming from, different countries or continents. In all their various forms these world families share one feature in common: they are the focal point in which different aspects of the globalized world become embodied in the personal lives of individuals. Whether they like it or not, lovers and relatives in these families find themselves confronting the world in the inner space of their own lives. The conflicts between the developed and developing worlds come to the surface in world families- they acquire faces and names, creating confusion, surprise, anger, joy, pleasure and pain at the heart of everyday life. This path-breaking book will appeal to a wide readership interested in the changing character of love in our times.
