In a breakthrough, Honda's humoid robot Asimo successfully recognized 3 different voice commands. Japanese researchers have reprogrammed Honda’s Asimo humanoid robot to differentiate between voices to understand up to three humans shouting at once.

Hiroshi Okuno at Kyoto University, and Kazuhiro Nakadai at the Honda Research Institute in Saitama have attributed Asimo’s new mind-blowing ability to a software they designed, called HARK.

Their software employs the use of eight microphones to work out where each voice is coming from, and isolate it from other sound sources. After that, an algorithm works out how reliably it has extracted an individual voice, and then passes it onto speech-recognition software to decode, say the researchers.

The HARK software – when installed into the Asimo robot – can follow up to three persons speaking simultaneously with an accuracy of 70-80 per cent.

In future machines like Asimo may help human in daily routine jobs, and may even perform better. The first step has been taken.
