Title: The Innovative Mind of Mark Randolph

Introduction

Mark Randolph is an accomplished inventor based in Kildeer, IL (US). He holds a total of 3 patents that showcase his expertise in speech detection and dialog recognition technologies. His contributions to the field have made a significant impact on how voice interactions are processed and understood.

Latest Patents

One of Randolph's latest patents is titled "Method and apparatus for speech detection using time-frequency variance." This invention involves a sophisticated process where speech is first bandpass filtered to split it into banks of sub-bands. A matrix of shift registers stores each sub-band of speech, and a power determining circuit measures the individual power of the speech stored in each shift register element. A variance combining circuit then combines these measurements to provide a variance for the individual shift registers. Finally, a comparator circuit compares the variance with at least one threshold to indicate whether speech is detected.

Another notable patent is "Dialog recognition and control in a voice browser." This invention enables a voice browser dialog for multimodal interaction, utilizing a multimodal markup document with fields that have markup-based forms. A voice browser driver on a communication device provides fragments and identifiers that identify these fragments. The implementation resides on a remote voice server, which receives the fragments and downloads a plurality of speech grammars. Input speech is then matched against these grammars associated with the corresponding identifiers received in a recognition request.
