Title: Innovations by Sungyub D Yoo
Introduction
Sungyub D Yoo is an accomplished inventor based in Dublin, CA (US). He has made significant contributions to the field of automatic speech recognition, holding a total of 3 patents. His work focuses on enhancing user interaction with devices through innovative signal processing methods.
Latest Patents
One of his latest patents is titled "Automatic speech recognition imposter rejection on a headphone with an accelerometer." This invention introduces a signal processing method that determines whether a detected key-phrase is spoken by the wearer of a headphone. The method utilizes an accelerometer signal and a microphone signal to detect the key-phrase and generate a voice activity detection (VAD) signal. It then assesses whether the VAD signal indicates that the key-phrase is indeed spoken by the headphone wearer, ultimately triggering a virtual personal assistant (VPA) when confirmed.
Another notable patent is the "Noise-dependent audio signal selection system." This device implements an automatic speech recognition triggering system that includes at least one processor. The processor receives audio signals from multiple microphones and generates a third audio signal directed towards the user's mouth. It also determines the presence of wind noise in the audio signals, allowing for a more accurate identification of the user's voice.
