Informationen zum Autor Gillian M. Davis Klappentext This book provides a comprehensive introduction to modern techniques for removing or reducing background noise from a range of speech-related applications. Self-contained, it provides the necessary background in a tutorial style chapter, then focuses on system aspects, digital algorithms, and implementation. The final section explores a variety of special applications and the noise reduction results achievable with the techniques presented. Noise Reduction in Speech Applications thus prepares readers to determine if digital noise reduction will solve problems in their own systems designs and how to make the best use of the technologies available.
