Noise and distortion that degrade the quality of speech signals can come from any number of sources. The technology and techniques for dealing with noise are almost as numerous, but it is only recently, with the development of inexpensive digital signal processing hardware, that the implementation of the technology has become practical.

Noise Reduction in Speech Applications provides a comprehensive introduction to modern techniques for removing or reducing background noise from a range of speech-related applications. Self-contained, it starts with a tutorial-style chapter of background material, then focuses on system aspects, digital algorithms, and implementation. The final section explores a variety of applications and demonstrates to potential users of the technology the results possible with the noise reduction techniques presented.

The book offers chapters contributed by international experts, a practical, systems approach, and numerous references. For electrical, acoustics, signal processing, communications, and bioengineers, Noise Reduction in Speech Applications is a valuable resource that shows you how to decide whether noise reduction will solve problems in your own systems and how to make the best use of the technologies available.

What allows certain individuals and groups to maintain control over the actions and lives of others? Linguistic anthropologist Elizabeth Keating went to the island of Pohnpei, in Micronesia, and studied how people use language and other semiotic codes to reproduce and manipulate status differences. The result is this inside view of how language works to create power and social inequality. This book challenges widely held theories on the nature of social stratification, including women's roles in creating hierarchy.

In a twenty-first-century global economy, in which multinational companies coordinate and collaborate with partners and clientele around the world, it is usually English that is the parlance of business, research, technology, and finance. Most assume that if parties on both ends of the conference call are fluent English speakers, information will be shared seamlessly and without any misunderstanding. But is that really true? Words Matter examines how communications between transnational partners routinely break down, even when all parties are fluent English speakers. The end result is lost time, lost money, and often discord among those involved. What's going wrong? Contrary to a common assumption, language is never neutral. Its is heavily influenced by one's culture and can often result in unintended meanings depending on word choice, a particular phrase, or even one's inflection. A recent study of corporate managers found that one out of five projects fail primarily because of ineffective transnational communication, resulting in the loss of millions of dollars. In Words Matter, you will venture into the halls of multinational tech companies around the world to study language and culture at work; learn practical steps for harnessing research in communication and anthropology to become more skilled in the digital workplace; and learn to use the "Communication Plus Model," which can be easily applied in multiple situations, leading to better communication and better business outcomes.
