In article number 1904020, Keon Jae Lee and co‐workers review recent developments in speech recognition, in terms of flexible piezoelectric materials, self‐powered sensors, machine‐learning algorithms, and speaker recognition. Such systems will play an innovative interface in artificial intelligence services.
Flexible piezoelectric acoustic sensors have been developed to generate multiple sound signals with high sensitivity, shifting the paradigm of future voice technologies. Speech recognition based on advanced acoustic sensors and optimized machine learning software will play an innovative interface for artificial intelligence (AI) services. Collaboration and novel approaches between both smart sensors...
