Speech Signal Analysis A speech signal is an acoustical signal that can be converted into an electrical signal with a microphone. The electrical signal can then be converted into a series of numbers (x) that represents the amplitudes of the electrical signal values. These numbers can be stored in data files so that the speech signal can be analyzed using computer programs Suppose that we are interested in analyzing speech signals for the following words "one," "two," "three" The goal of this analysis is to develop ways of identifying the correct digit from a data file containing the utterance of an unknown digit. The following figure contains a plot of an utterance of the digit "zero" Speech Signal 0.3 0.2 0.1 0 -0.2 0.05 0.15 Time. s 0.1 0.2 0.25 0.3
