Title: Innovations of Koen Bernard Vos in Speech Decoding

Introduction

Koen Bernard Vos is an accomplished inventor based in Singapore, SG. He has made significant contributions to the field of speech encoding and decoding, holding a total of 9 patents. His work focuses on improving the performance of speech codecs, particularly in low bitrate scenarios.

Latest Patents

One of his latest patents is centered around phase reconstruction in a speech decoder. This innovation addresses phase quantization during speech encoding and phase reconstruction during speech decoding. For instance, to encode a set of phase values, a speech encoder may omit higher-frequency phase values and represent some of the phase values as a weighted sum of basis functions. In decoding, a speech decoder reconstructs phase values using a weighted sum of basis functions and synthesizes higher-frequency phase values from lower-frequency ones. These innovations enhance the performance of speech codecs, especially when data is transmitted over networks with limited bandwidth or quality issues.
