HEARBO (HEAR-ing roBOt) developed by Honda Research Institute in Japan has superior auditory senses. The robot uses a 3-step paradigm that includes localization, separation and recognition to help distinguish voices and sounds in even a “noisy” location. Extending on the traditional beamforming approach that first focuses on sound, carries out noise reduction, and then attempts to understand a command, the HEARBO can take in all sounds and then separate and analyze them. Up to four different sounds can be detected and recognized at once. Scientists hope to increase the voice detection capabilities by adding additional microphones.
