(Phys.org)—Research seeking to improve the features and functions of robots has made impressive gains with prototypes of robots that can help out in settings that range from assistive living, to hospital care, to inventory-taking retail stores. One area of robot technology receiving special attention at Honda is "robot audition." How effectively can scientists fashion robots that can hear? And, by hearing, how can hearing be ramped up to include speech recognition, even with noise interference? HEARBO, which stands for (HEAR-ing roBOt) is a robot that has been developed at Japan's Honda Research Institute–(HRI-JP), and its creators want HEARBO to stand out as an above-average example of how robots can understand sound. Their line of research is called Computational Auditory Scene Analysis.
In brief, HEARBO can pick up, distinguish, and analyze multiple simultaneous sound sources without difficulty. HEARBO's edge is in the word "analyze," as it can sift and sort different sounds going on at the same time, such as children playing on one side of the room, with a doorbell ringing on the other.
The Honda researchers say that the robot has a three-step process of: localization, separation, and recognition. Sound Source Localization (SSL) in robot audition conveys the location and number of sound sources, used for sound source separation. "Since robots should work in real-time and localize sound sources in a noisy environment, SSL for robots mainly requires noise-robustness, high-resolution, and real-time processing," according to Honda researchers.
