ABSTRACT
An experimental analysis of the relation between speech
signal segment power and the source direction-of-arrival es-
timation accuracy is conducted. A total of 10 different speak-
ers, including both male and female speakers, totaling to
approximately 2 hours of speech are used to analyze the
performance of the Phase Transform, the Maximum Likeli-
hood, and the Unfiltered Cross Correlation time-delay esti-
mation techniques. For female speakers, it is determined
that the Phase Transform technique has a lower percent-
age of anomalies and a lower direction-of-arrivalroot mean-
square error (DOA RMSE). Conversely, for male speakers,
it is determined that the Unfiltered Cross Correlation has a
