Abstract

The purpose of this thesis is to create a system for detection of speaker position in a closed room equipped with microphone array. It deals with two algorithms for sound source localization, namely beamforming and time difference of arrival. The methods were implemented on the provided hardware, reliability of the methods was tested and results were evaluated. The results have shown that both used methods were relatively accurate if used in small space (approx. 3×3 m). Shortcomings of the solution were analyzed in detail, possible improvements were proposed. This work can be used as a basis for creating embedded systems for sound source localization.

Keywords

microphone array, sound source localization, delay and sum, time difference of arrival
