Title: The Innovations of Andre E Desblache

Introduction

Andre E Desblache is a notable inventor based in Nice, France. She has made significant contributions to the field of technology, particularly in voice activity detection and echo cancellation. With a total of 9 patents to her name, her work has had a considerable impact on communication systems.

Latest Patents

Among her latest patents is a process for voice activity detection. This innovative method detects speech signal presence in a Voice Activity Detector (VAD) through a two-step process. The first step involves determining if the signal energy is above a certain threshold, which indicates presence, while below the threshold leads to ambiguity. The second step resolves this ambiguity by testing the rate of change of spectral parameters. Another significant patent involves a method for initializing a filter in an echo canceller used in telephone systems. This method includes transmitting sequences of real and imaginary components of a signal with a flat spectrum, receiving and storing echoes, and calculating the fast Fourier transform of the stored sequences to derive the initial coefficients of the filter.
