Book Description
Results of a study of effects of broad-band noise on speech intelligibility and voice quality are presented, with a comparison of three methods for evaluating speech signals: the Diagnostic Rhyme Test (DRT) for speech intelligibility, the Diagnostic Acceptability Measure (DAM) test for voice quality and acceptability, and the Mean Opinion Score (MOS), also for evaluating speech quality and acceptability. Speech samples were combined with broad-band noise, with accurate calibration of speech-to-noise energy ratios by using a new measurements algorithm developed under RADC sponsorship. Four scrambling (randomizations) of the Diagnostic Rhyme Test were prepared with each of three male speakers, for assessing speech intelligibility. Connected speech samples from the three speakers were prepared for assessing voice quality and acceptability. The processed speech samples were digitally recorded for subsequent presentation to listener crews.

Book Description
Quality of Telephone-Based Spoken Dialogue Systems is a systematic overview of assessment, evaluation, and prediction methods for the quality of services such as travel and touristic information, phone-directory and messaging, or telephone-banking services. A new taxonomy of quality-of-service is presented which serves as a tool for classifying assessment and evaluation methods, for planning and interpreting evaluation experiments, and for estimating quality. A broad overview of parameters and evaluation methods is given, both on a system-component level and for a fully integrated system. Three experimental investigations illustrate the relationships between system characteristics and perceived quality. The resulting information is needed in all phases of system specification, design, implementation, and operation. Although Quality of Telephone-Based Spoken Dialogue Systems is written from the perspective of an engineer in telecommunications, it is an invaluable source of information for professionals in signal processing, communication acoustics, computational linguistics, speech and language sciences, human factor design and ergonomics

Book Description
Karlheinz Brandenburg and Mark Kahrs With the advent of multimedia, digital signal processing (DSP) of sound has emerged from the shadow of bandwidth limited speech processing. Today, the main appli cations of audio DSP are high quality audio coding and the digital generation and manipulation of music signals. They share common research topics including percep tual measurement techniques and analysis/synthesis methods. Smaller but nonetheless very important topics are hearing aids using signal processing technology and hardware architectures for digital signal processing of audio. In all these areas the last decade has seen a significant amount of application oriented research. The topics covered here coincide with the topics covered in the biannual work shop on “Applications of Signal Processing to Audio and Acoustics”. This event is sponsored by the IEEE Signal Processing Society (Technical Committee on Audio and Electroacoustics) and takes place at Mohonk Mountain House in New Paltz, New York. A short overview of each chapter will illustrate the wide variety of technical material presented in the chapters of this book. John Beerends: Perceptual Measurement Techniques. The advent of perceptual measurement techniques is a byproduct of the advent of digital coding for both speech and high quality audio signals. Traditional measurement schemes are bad estimates for the subjective quality after digital coding/decoding. Listening tests are subject to sta tistical uncertainties and the basic question of repeatability in a different environment.

Book Description
The third volume of Recent Advances in Otolaryngology brings clinicians and trainees fully up to date with the latest developments in the rapidly changing field of otolaryngology. Nineteen chapters present new concepts, surgical advances and imaging modalities in each of the subspecialties of otolaryngology. Each chapter begins with a brief summary of the topic, followed by all the recent advances and comprehensive references. A complete chapter is dedicated to geriatric otolaryngology, an emerging subspecialty. Written by an internationally-recognised author and editor team from the US and Europe, this comprehensive manual includes more than 270 images, illustrations and tables. The annual publication cycle of this series ensures the content is current, topical and highly relevant to clinicians and trainees.
