Voice Quality Measurement

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.

Offers a new model of vocal tract articulation that explains laryngeal and oral voice quality, both auditorily and visually, through language examples and familiar voices.

Annotation Voice/Data Integration on Cisco Networks is both a conceptual reference and a practical how-to book that bridges the gap between existing telephony networks and the new world of packetized voice over data networks. Technologies are explained in a context that gives the reader a holistic understanding of voice/data integration. Reader can then follow a complete process to design and implement a variety of network scenarios, leveraging the author's experience with real voice/data networks. The audio accompaniment on CD-ROM will be an excellent companion to demonstrate the expected voice quality using different voice/data networking scenarios. This will allow professionals in the field to demonstrate different sound quality levels to customers.

“By 2008, some 2 billion people will be using mobile phones and devices, in many cases to access advanced data services. Against this backdrop, the need for efficient and effective network design will be critical to the success of increasingly complex mobile networks.” Simon Beresford-Wylie (SVP, Nokia Networks) With the complexity of the cellular networks increasing day by day, a deeper understanding of the design and performance of end-to-end cellular networks is required. Moreover, all the types of networks from 2G-2.5G-3G seem to co-exist. Fundamentals of Cellular Network Planning and Optimisation covers end-to-end network planning and optimisation aspects from second generation GSM to third generation WCDMA networks including GPRS and EDGE networks. All the sub-systems of the network i.e. radio network, transmission network and core network have been covered with focus on both practical and theoretical issues. By bringing all these concepts under one cover, this book becomes essential reading for the network design engineers working either with cellular service vendors or operators, experts/scientists working on end-to-end issues and undergraduate/post-graduate students. Key Highlights: Distinctly divided into four parts: 2G (GSM), 2.5G (GPRS & EDGE), 3G (WCDMA) and introduction to 4G (OFDM, ALL-IP, WLAN Overview) respectively Each part focuses on the radio, transmission and core networks. Concentrates on cellular network planning process and explains the underlying principles behind the planning and optimizing of the cellular networks. The text will serve as a handbook for anyone engaged in the study, design, deployment and business of cellular networks.
