Latest Patents

One of Hsu's latest inventions is an anti-spoofing authentication system. This system includes an image capture device that converts received light into an image signal representing a captured image. It also features a microphone that converts sound waves into a voice signal, along with a face detection device that identifies human faces in the captured image. This device includes a lip detection feature that detects lip characteristics associated with the identified face. Additionally, a voice activity detection (VAD) device is incorporated to detect the presence of human voice in the voice signal. The anti-spoofing device then identifies any spoofing attacks based on the detected lip features and human voice.

Another significant invention by Hsu is a sound source localization system. This system comprises a microphone array made up of multiple microphones, each converting sound waves into corresponding voice signals. It includes a room shape estimator that determines the room's shape, producing a location map and a corresponding template voice feature map. This map consists of template voice features associated with a virtual sound source located at various positions. The system outputs a room reliability score, indicating confidence in the determined room shape. A lookup table (LUT) pre-stores the location map and the corresponding template voice feature map, while a localizer determines the location of a sound source based on room reliability and the similarity between the voice feature associated with the sound source and the template voice features.
