Book Description
This comprehensive book explores the many facets of measuring voice quality. Voice quality is a concept that is widely recognized and applied, yet very difficult to define in a way that is universally satisfactory. A number of experts consider such topics as perceptual assessment, instrumental (objective) assessment, and various voice states and disorders. Contributors with a wide scope of experience present perspectives and ideas on how voice quality can be assessed with improved validity and reliability.

Book Description
It is becoming crucial to accurately estimate and monitor speech quality in various ambient environments to guarantee high quality speech communication. This practical hands-on book shows speech intelligibility measurement methods so that the readers can start measuring or estimating speech intelligibility of their own system. The book also introduces subjective and objective speech quality measures, and describes in detail speech intelligibility measurement methods. It introduces a diagnostic rhyme test which uses rhyming word-pairs, and includes: An investigation into the effect of word familiarity on speech intelligibility. Speech intelligibility measurement of localized speech in virtual 3-D acoustic space using the rhyme test. Estimation of speech intelligibility using objective measures, including the ITU standard PESQ measures, and automatic speech recognizers.

Book Description
The quality of telecommunication voice services has become an important issue due to the evolving and liberalized market. With the advent of new technologies, however, a diversification takes place which makes it necessary to carefully plan and observe network quality. Speech communication quality - as it is perceived by the user or customer of a service - carries a multidimensional nature, a fact which must be reflected in its assessment and prediction with quality models. In this book a new schematic is developed which classifies different entities contributing to the quality of a service. It takes into account conversational user as well as service-related contributions. Starting from this concept, perceptively relevant constituents of speech communication quality are identified. A simulation model is developed and implemented, based on physical elements of the transmission configuration. It allows the perceptively most relevant parameters to be simulated, in real time and for the conversation situation. The book gives a valuable overview on assessment needed for reliably measuring the different quality dimensions. For the planning of telephone networks, quality models are presented which aim at predicting mouth-to-ear quality as it would be perceived by a user of the system. These models are an important tool for the planner of telecommunication networks, as they allow the expected quality to be estimated in advance, even before the network has been set up. Two well-known models (the SUBMOD and the E-model) are analyzed in more detail, with an emphasis on the psychoacoustic and psychophysical backgrounds. It turns out that model predictions are satisfactory for many types of degradations, but they can still be improved especially for new types of impairments. Proposals are made for quality model enhancement and combined approaches. Due to its `handbook' character, this book is an invaluable source of background information for anyone working in the field of speech quality assessment as well as telephone network planning and operation.

Book Description
Foundations of Voice and Speech Quality Perception starts out with the fundamental question of: "How do listeners perceive voice and speech quality and how can these processes be modeled?" Any quantitative answers require measurements. This is natural for physical quantities but harder to imagine for perceptual measurands. This book approaches the problem by actually identifying major perceptual dimensions of voice and speech quality perception, defining units wherever possible and offering paradigms to position these dimensions into a structural skeleton of perceptual speech and voice quality. The emphasis is placed on voice and speech quality assessment of systems in artificial scenarios. Many scientific fields are involved. This book bridges the gap between two quite diverse fields, engineering and humanities, and establishes the new research area of Voice and Speech Quality Perception.

Book Description
Phonetics - the study and classification of speech sounds - is a major sub-discipline of linguistics. Bringing together a team of internationally renowned phoneticians, this handbook provides comprehensive coverage of the most recent, cutting-edge work in the field, and focuses on the most widely-debated contemporary issues. Chapters are divided into five thematic areas: segmental production, prosodic production, measuring speech, audition and perception, and applications of phonetics. Each chapter presents an historical overview of the area, along with critical issues, current research and advice on the best practice for teaching phonetics to undergraduates. It brings together global perspectives, and includes examples from a wide range of languages, allowing readers to extend their knowledge beyond English. By providing both state-of-the-art research information, and an appreciation of how it can be shared with students, this handbook is essential both for academic phoneticians, and anyone with an interest in this exciting, rapidly developing field.

Book Description
A complete and systematic treatment of signal processing for VoIP voice and fax This book presents a consolidated view and basic approach to signal processing for VoIP voice and fax solutions. It provides readers with complete coverage of the topic, from how things work in voice and fax modules, to signal processing aspects, implementation, and testing. Beginning with an overview of VoIP infrastructure, interfaces, and signals, the book systematically covers: Voice compression Packet loss concealment techniques DTMF detection, generation, and rejection Wideband voice modules operation VoIP Voice-Network bit rate calculations VoIP voice testing Fax over IP and modem over IP Country deviations of PSTN mapped to VoIP VoIP on different processors and architectures Generic VAD-CNG for waveform codecs Echo cancellation Caller ID features in VoIP Packetization—RTP, RTCP, and jitter buffer Clock sources for VoIP applications Fax operation on PSTN, modulations, and fax messages Fax over IP payload formats and bit rate calculations Voice packets jitter with large data packets VoIP voice quality Over 100 questions and answers on voice and more than seventy questions and answers on fax are provided at the back of the book to reinforce the topics covered throughout the text. Additionally, several clarification, interpretation, and discussion sections are included in selected chapters to aide in readers' comprehension. VoIP Voice and Fax Signal Processing is an indispensable resource for professional electrical engineers, voice and fax solution developers, product and deployment support teams, quality assurance and test engineers, and computer engineers. It also serves as a valuable textbook for graduate-level students in electrical engineering and computer engineering courses.

Book Description
The characteristic voice quality of a speaker conveys to listeners a wealth of information about his physical, psychological and social attributes. For this reason, voice quality is of interest to a wide range of disciplines, including linguistics, phonetics and speech science, speech pathology, sociology, psychology, medicine, and communication engineering. Literature on voice quality is, consequently, scattered through a correspondingly wide range of publications. While this bibliography is unlikely to be exhaustive, it aims to be comprehensive. Exceptions to this are purely medical literature and literature on speech pathology; also, although a number of different languages are represented, works in English received the principal coverage.
