10. The computer program product of claim 7 , wherein the program instructions of mapping, by the computer, the one or more features of the sound construct further comprises: sequencing, by the computer, out at least a portion of features of the one or more features to provide a feature sequence; and comparing, by the computer, the feature sequence to one or more defined sequences to identify one or more sound constructs of a selected language.
7. A computer program product for identifying at least one speaker from a speech segment obtained by a computer comprising the steps of determining one or more words of the speech segment by identifying one or more portions of a sound wave having a sound wave contour between silences, the computer comprising at least one processor, one or more memories, one or more computer readable storage media, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by the computer to perform a method comprising: analyzing, by the computer, the sound wave contour of at least a portion of the sound wave to determine one or more variations within the sound wave contour; assigning, by the computer, one or more features to the one or more variations by selecting, by the computer, a feature from a plurality of features based on slope characteristics of the sound wave contour representing the one or more portions of a sound wave having a sound wave contour between silences; mapping, by the computer, one or more assigned features to one or more sound constructs, wherein the one or more sound constructs are at least part of word; determining, by the computer, parameters of the assigned features and order in which the parameters occur within the sound wave contour to indicate the start of a vowel in the speech segment; grouping, by the computer, the parameters into predefined characteristics; combining, by the computer, the predefined characteristics into a voice characteristic group; and comparing, by the computer, the voice characteristic group to a plurality of existing voice characteristic groups each of the plurality of voice characteristic groups being attributed to one of the plurality of single speakers and, if the predefined characteristics of the voice characteristic group match the predefined characteristics of one of the plurality of existing voice characteristic groups, by the computer, the sound construct to a speaker identified by the existing voice characteristic group matching the voice characteristic group.
