Speech coding: a computer laboratory textbook, Volume 3
Wiley, Jan 1, 1996 - Computers - 184 pages
Puts a wealth of speech analysis tools at your fingertips and allows the reader to gain good intuitive sense of how modern speech coders work. Covers all the basic approaches found in speech coding and describes the algorithms in both simple parametric terms and complete equation form. The book is packed with exercises and projects for hands-on experimentation with algorithms. Plus, the accompanying user-friendly, graphical interface software helps to develop a practical, intuitive sense of how modern speech coders work.
