ABSTRACT
An experimental analysis of the relation between speech
signal segment power and the source direction­of­arrival 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 time­delay esti­
mation techniques. For female speakers, it is determined
that the Phase Transform technique has a lower percent­
age of anomalies and a lower direction­of­arrival root mean­
square error (DOA RMSE). Conversely, for male speakers,
it is determined that the Unfiltered Cross Correlation has a
