From the reviews: "The authors discuss the problem of quality enhancement of speech signals bandlimited by telephone networks with and without the presence of noise. ... For the interested reader the book is worth reading since it covers together with basic aspects related to speech processing clearly described new results and techniques with the special feature that they can be optionally used without changing the existing hardware." (Liviu Goras, Zentralblatt MATH, Vol. 1172, 2009)

• Speech Generation.- Analysis Techniques for Speech Signals.- Excitation Signal Extension.- Broadband Spectral Envelope Estimation.- Quality Evaluation.- Summary.
