| Research Abstract |
In this research, an effectiveness of the realtime multiple talker tracking method developed by the representative author under the support of this grant money has been studied. Through several experimental results carried out in the actual environment, it was verified that a mis-estimation by spatial aliasing could be avoided by the proposed system even when wide width microphones were used for estimation. Moreover, a novel algorithm has been proposed under a new framework. The algorithm used the PSO (Particle Swarm Optimization) which is one of the swarm inteligence algorithms. In addition, the same talker tracking problem was resolved even if the new algorithm was used for the tracking. A realtime tracking performance was shown by the several experimental results.
