Voice recognition (VR) leads the era of future internet of things (IoT), which has the most straight forward user interface. One of its advantages is that it can process real-time information even when a userí»s are incapable. However, current VR technology has several limitations such as high power consumption and the unnatural recognition of conversations because the conventional VR technology is based on complicated algorithm. In contrast, a human cochlear organ used, simply splits frequency spectrum and effectively processes the acoustic signals of sophisticated human language.
We have successfully separated voice frequency using our flexible inorganic piezoelectric materials by mimicking a human cochlear, that can be used for future low power VR technology of mobile and consumer electronics.
