Artificial intelligence device for providing notification to user using audio data and method for the same

This device listens for specific sounds using a microphone. It automatically adjusts the microphone's sensitivity, increasing it when the environment is quiet, to better detect a pre-stored "trigger sound." When a trigger sound is detected, the device plays a corresponding notification to the user, sometimes alongside the original sound.

Why it matters: Filed before widespread low-power edge AI for audio processing. Since 2019, the accuracy and efficiency of sound event detection and adaptive gain control on embedded systems have dramatically improved, making always-on listening more practical.

Status: ExpiredProtection ended and was never renewed
How hard to build: ModerateSoftware logic, audio processing, standard electronics.
