“Sounds” & “light” in the context of intelligence science is a fundamental medium shared by humans and animals. Animals have developed the ability to detect enemies and to transmit information using “sounds” & “light”. On the other hand, “Kotoba (multi-modal spoken language in Japanese)” is the intelligence function that humans have developed the most compared to other animals.
We use these intelligence in daily life without any difficulty, but it is very difficult for robots and machines to use “sound” and “Kotoba”. For instance, “Kotoba” can be used in many different contexts that are difficult to quantify. For example, the meaning of a communication may be different in different situations, or between the written form and when spoken in a conversation.
Therefore, the Honda Research Institute Japan (HRI-JP) is studying the science of sound/light to uncover how to recognize sounds/light, and is also doing research on artificial intelligence on how to implement the intelligence on a computer to understand the sounds/light, and neuroscience to learn from the processes in the brain that naturally understands them.
