Abstract
This thesis investigates the possibility of Speaker
Identification through the use of Nasal Phonation. Short
segments of a restricted set of words from one speaker
were sampled, processed, and the resulting vector is used
to represent the speaker. Representative vectors were
formed for several speakers and correlated with vectors
representing individual words from "test" speakers. The
magnitude of the correlations of the word vectors with
various speaker vectors were used to identify the speaker.
This work expands on earlier work done in this field to
the extent that it attempts to remove the subjective preparation
of data and replace this instead with an objective
process of computer mechanization. Some limited success
was achieved and, just as important, critical problem areas
are noted which, if improved upon as recommended, promise
an improved identification capability. Two different word
lists fundamental to the identification process were also
investigated. Some data was obtained but it was not sufficient
to suggest that one word list would be more productive
than the other when used as the basis for speaker identification.
Recommendation is made to pursue further research in
Speaker Identification using computer programming established
during work on this thesis.
