Title: Dubravko Biruski: Innovator in Speech Recognition Technology

Introduction

Dubravko Biruski is a prominent inventor based in Palo Alto, CA (US). He has made significant contributions to the field of speech recognition technology, holding a total of 5 patents. His work focuses on enhancing user interaction with devices through innovative audio processing methods.

Latest Patents

One of Dubravko's 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, subsequently triggering a virtual personal assistant (VPA).

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 is designed to receive audio signals from multiple microphones and generate a third audio signal corresponding to a voice beam directed at the user's mouth. It also determines the presence of wind noise in the audio signals and selects the appropriate audio signal for user recognition.
