Title: The Innovations of Edmond F. Deprettere

Introduction

Edmond F. Deprettere is a notable inventor based in The Hague, Netherlands. He has made significant contributions to the field of speech coding, holding a total of 2 patents. His work has had a profound impact on the way speech signals are processed and synthesized.

Latest Patents

One of his latest patents is a multi-pulse excitation linear-predictive speech coder. This innovative device operates using an analysis-by-synthesis method to determine excitation. The coder includes an LPC-analyzer, a multi-phase excitation generator, and means for forming an error signal that represents the difference between an original speech signal and a synthetic one. The system is designed to minimize a predetermined measure of the weighted error signal, thereby enhancing the quality of synthesized speech. Another significant patent involves a multipulse excitation signal that serves as a better approximation than a single-pulse excitation signal. This invention searches for a pulse that minimizes the difference between synthesized and reference signals, utilizing an averaging function of a weighted error signal.
