| Research Abstract |
In this research, we propose a smart sensor which can easily and less costly utilize a sound event recognition. We also propose an Instant Learning method which automatically configures an appropriate set of parameters in a DP matching based recognition process for the target event by evaluating several combinations of parameters. Based on our proposal, we have designed and implemented an Instant Learning Sound Sensor using small DSP processor. By evaluation experiment, we confirmed the smart sensor can automatically choose a proper set of parameters for various sound event with almost over 80% accuracy. We also confirm the utilization of multiple sensors to recognize the up/down of stairs, or positions of knocking place on the desks or walls.
