lected a very wide range of topics, and to cover them in complete depth would
be extremely difficult. There are a number of ways in which a book of this
type could be organized. For example, it could be organized with respect to
the signal representations of Figure 1.15. Alternatively, a book on speech processing
could be written to emphasize application areas based on the hierarchy
of Figure 1.17. A third possibility would be to organize the book with respect
to signal processing methods. The approach we have chosen is based on the
ideas presented in the Speech Stack (Figure 1.1) where we choose to first discuss
the fundamental concepts in speech production and perception, followed
by discussions of the four signal processing representations of speech, followed
by a chapter on speech measurement and parameter estimation systems, and
ending with chapters on the major speech applications. As such, the remaining
chapters of this book discuss the following topics:
Chapter 2 – review of digital signal processing with emphasis on techniques
crucial to digital speech processing systems
Chapter 3 – the fundamentals of speech generation/production in humans
Chapter 4 – the fundamentals of speech perception in humans
Chapter 5 – the theory of sound propagation in the human vocal tract
Chapter 6 – time-domain methods for speech processing
Chapter 7 – frequency-domain methods for speech processing and the
short-time Fourier transform
Chapter 8 – homomorphic methods for speech processing and cepstral
analysis
Chapter 9 – linear predictive coding methods for speech processing
Chapter 10 – algorithms for measuring and estimating fundamental
properties and attributes of speech signals
