Advances In Audio And Speech Signal Processing: Technologies And Applications

E-Book Overview

Audio and speech processing have achieved important status in development in the last three decades, improving the standard of living of many people. Regarding these applications, several signal processing algorithms have been developed to assist the speech impaired and improve the learning ability of children. Advances in Audio and Speech Signal Processing: Technologies and Applications provides a comprehensive approach of signal processing tools regarding the enhancement, recognition, and protection of speech and audio signals. Advances in Audio and Speech Signal Processing: Technologies and Applications offers researchers and practitioners the information they need to develop and implement efficient signal processing algorithms in the enhancement field.
