Oscar Tosi has undertaken a definitive challenge in his attempt to review, interpret, and address the controversial issue of voice identification. His work has resulted in a rather easily read and approachable five-chapter volume covering the theoretical, technical, and, above all, legalistic aspects of man's desire to achieve a fully proven means of speaker identification from acoustic cues alone. Tosi introduces the reader to the subject of voice identification with an outline of the historical background and terminology used in this field (chapter 1).
In chapter 2, the application of euclidian distances is discussed with reference to the main subject of the book. Theoretical aspects of normal voice and speech production are primarily focused on Fourier analysis. Basic acoustics and phonetics and models of voice communication are treated rather simplistically for a sophisticated reader, but will provide core information for an audience less familiar with these topics.
