Latest Patents

Dixon's latest patents include advancements in adaptive automatic discrete utterance recognition. This innovative system allows for the adaptation of prototype utterances to meet the needs of the talker during continuous speech. The system is designed to recognize single prototype utterances without requiring tedious multiple recitations for training. It begins with initial training through a single utterance of a prototype vocabulary and continues to operate as long as utterances are recognized. When an unrecognized utterance is detected, the system prompts the talker to choose from prototype vocabulary keyword candidates, which they can then utter.

Another significant patent involves an effective wind/breath screen for microphones. This design features a rigid perforated structure that encloses the microphone, physically isolating it with a surrounding pad of air. A porous layer encloses the rigid structure, creating a dead air pad that allows speech signals to reach the microphone without substantial attenuation while suppressing wind and breath noise. This windscreen is particularly optimized for voice data entry applications.
