| Abstract: | The technology of sound source localization can localize the direction and position of a sound source relative to a robot.Sound source localization system for robot audition can greatly improve the ability of a robot to interact with external conditions.The summary and analysis of sound source localization for robot audition can significantly promote the development of intelligent robots.In this work,first,the characteristics of sound source localization for robot audition were summarized.The key technologies were summarized,including the time delay of arrival,steered beamforming,high resolution spectral estimation,binaural,active audition,and audio-visual.Then,the models of a microphone array were classified,and the performances of seven typical systems based on a 3-D microphone array,2-D microphone array,and binaural were compared.Finally,the applications of a sound source localization system of robot audition were summarized.Several issues that sound source localization systems face as well as development trends were analyzed. |
