• 論文抄録 / 内容記述: This paper describes a speaker localization system using two microphonesembedded in the head of the SIG-2 humanoid robot. Nowadays, studies based onmicrophone arrays utilize many microphones to obtain high detectionperformance in acoustical engineering. However, using multiple microphoneswould raise costs and hinder maintenance. To achieve good results in speakerlocalization only with two low-cost microphones, we employ the statisticalmodel-based voice activity detection (VAD) and a sound-source-directionestimator based on the generalized cross-correlation with phase transform(GCC-PHAT). The experimental results show that SIG-2 can localize a callerreliably when the speaker calls robot's name in the azimuth.
