5. The Voice Signal and Its Information Content—2
Abstract
Information in the voice signal is embedded in both its time progression and in its spectral content, i.e. in its time domain and spectrographic domain respectively. Within these domains, information relevant to profiling may be present in the patterns exhibited by specific characteristics of the voice signal. The signal may however also have characteristics that are not evident in these domains, and must be searched for in other (derivative) mathematical domains where the relevant patterns become more tangible for measurement and analysis. This, however, is the subject of feature discovery—a subject that is discussed in Part II of this book. A third domain that reflects the information in the voice signal is that of physical or abstract models that simulate or explain the voice signal and the processes that generate it. We will refer to this as the model domain.
