要約(英語): As an omnidirectional sound source tracking using a square arrangement microphone array, a role selecting method has been developed. In the method, a role selection of each microphone pair is carried out to classify the estimated time-difference-of-arrivals to two roles based on a sensitivity difference between microphone pairs. However, there exist directions that two pairs have a high sensitivity at the same time. This situation prevents an assumption for applying the method. In this paper, square edge pairs also are incorporated to candidates for avoiding such a situation and aiming a performance improvement. The effectiveness of the method is shown through several experimental results.
