Download or read book Algorithms and Software for Predictive and Perceptual Modeling of Speech written by Venkatraman Atti and published by Springer Nature. This book was released on 2022-05-31 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the early pulse code modulation-based coders to some of the recent multi-rate wideband speech coding standards, the area of speech coding made several significant strides with an objective to attain high quality of speech at the lowest possible bit rate. This book presents some of the recent advances in linear prediction (LP)-based speech analysis that employ perceptual models for narrow- and wide-band speech coding. The LP analysis-synthesis framework has been successful for speech coding because it fits well the source-system paradigm for speech synthesis. Limitations associated with the conventional LP have been studied extensively, and several extensions to LP-based analysis-synthesis have been proposed, e.g., the discrete all-pole modeling, the perceptual LP, the warped LP, the LP with modified filter structures, the IIR-based pure LP, all-pole modeling using the weighted-sum of LSP polynomials, the LP for low frequency emphasis, and the cascade-form LP. These extensions can be classified as algorithms that either attempt to improve the LP spectral envelope fitting performance or embed perceptual models in the LP. The first half of the book reviews some of the recent developments in predictive modeling of speech with the help of MatlabTM Simulation examples. Advantages of integrating perceptual models in low bit rate speech coding depend on the accuracy of these models to mimic the human performance and, more importantly, on the achievable "coding gains" and "computational overhead" associated with these physiological models. Methods that exploit the masking properties of the human ear in speech coding standards, even today, are largely based on concepts introduced by Schroeder and Atal in 1979. For example, a simple approach employed in speech coding standards is to use a perceptual weighting filter to shape the quantization noise according to the masking properties of the human ear. The second half of the book reviews some of the recent developments in perceptual modeling of speech (e.g., masking threshold, psychoacoustic models, auditory excitation pattern, and loudness) with the help of MatlabTM simulations. Supplementary material including MatlabTM programs and simulation examples presented in this book can also be accessed here.

Available in PDF, EPUB and Kindle. Book excerpt: Multimedia Interactive Protocols and Systems (MIPS) is the brand new name of a workshop that has been successfully held for the ?rst time in 2002 in Coimbra, as the ?rst joint edition of two well established series of workshops: Interactive Distributed Multimedia Systems (IDMS) and Protocols for Multimedia Systems (PROMS). The area covered by Multimedia Interactive Protocols and Systems is indeed broad, since it includes technical and practical issues related to d- tributed multimedia technologies, applications and services, with emphasis on their deployment over next generation networks. The topics set for MIPS 2003 were: mobile and wireless multimedia systems; multimedia middleware and communication protocols; Quality of Service issues; resource management for multimedia services; active and programmable netw- king for multimedia applications; mobile agents for multimedia; multimedia d- tribution and transport; tra?c engineering and service engineering; ubiquitous computing; networked audio-video devices; development tools for distributed multimedia applications; multimedia applications such as video-on-demand, - gital video libraries, video games, virtual community, teleworking, teleteaching, e-commerce, virtual reality simulations; performance of protocols and applica- ons;contentmanagement;serviceaccess;security,authentication,privacy,wat- marking; accounting and tari? policing for multimedia teleservices; multimedia encoding and compression. The Call for Papers attracted more than 130 submissions from Europe, Asia and the Americas, covering most of the proposed topics. With the help of a very dedicated Program Committee and of a number of associate reviewers, subm- sions were carefully evaluated, with an average of three reviewers for each paper.

Download or read book Security and Privacy in Digital Rights Management written by Tomas Sander and published by Springer. This book was released on 2003-08-01 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ACM Workshop on Security and Privacy in Digital Rights Management is the ?rst scienti?c workshop with refereed proceedings devoted solely to this topic. The workshop was held in conjunction with the Eighth ACM Conference on Computer and Communications Security (CCS-8) in Philadelphia, USA on November 5, 2001. Digital Rights Management technology is meant to provide end-to-end so- tions for the digital distribution of electronic goods. Sound security and privacy features are among the key requirements for such systems. Fifty papers were submitted to the workshop, quite a success for a ?rst-time workshop. From these 50 submissions, the program committee selected 15 papers for presentation at the workshop. They cover a broad area of relevant techniques, including cryptography, system architecture, and cryptanalysis of existing DRM systems. Three accepted papers are about software tamper resistance, an area about which few scienti?c articles have been published before. Another paper addresses renewability of security measures. Renewability is another important security technique for DRM systems, and I hope we will see more publications about this in the future. I am particularly glad that three papers cover economic and legal aspects of digital distribution of electronic goods. Technical security measures do not exist in a vacuum and their e?ectiveness interacts in a number of ways with the environment for legal enforcement. Deploying security and an- piracy measures adequately requires furthermore a good understanding of the business models that they are designed to support.
