In this position paper, a fast real-time algorithm for the sound source localization system using microphone array is proposed. The algorithm includes three steps: Delay time estimation using time difference of arrival (TDOA); Searching area selection based on angle of arrival; and, Sound source localization using a newly golden section searching (GSS) method. Thanks to the first two steps, we can...
In this paper we present some preliminary results of our project for developing an office delivery robot with the functions of multimodal human-robot interactions. For the multimodal human-robot interactions, we utilize the embedded MCU, SPCE061A, to realize the speech recognition, and interactive dialogue capabilities, and use the single chip, AT-mega168, to implement the detection of sound sources,...
