Abstract

The calculation of time delay between a signal and its echo received at a microphone has been proven to be a useful parameter. Speech enhancement, speaker localization, speech and speaker recognition are few applications of TDE methods. We are implementing various methods for the estimation of time delay. These methods are implemented in MATLAB. The reason for choosing the MATLAB as the analysis and simulation tool is that it has more flexible choices to support the simulation and is easy to do modification or data recording. These methods are cross-correlation (CC), phase transform (PHAT). Various time-delay estimation techniques based on the cross-correlation functions are compared through simulations and measurements. Their simulation results are compared in terms of computation complexity, hardware implementation, precision, and accuracy.
