Title: Innovations of Hong Wang in Speech Processing

Introduction

Hong Wang is an accomplished inventor based in Bellevue, WA (US). She has made significant contributions to the field of speech processing, holding a total of 5 patents. Her work focuses on enhancing the quality of coded speech, particularly in low bit-rate scenarios.

Latest Patents

One of her latest patents is titled "Frequency domain postfiltering for quality enhancement of coded speech." This invention provides a method and system for performing postfiltering in the frequency domain to improve the quality of a speech signal. It is especially beneficial for synthesized speech resulting from codecs of low bit-rate. The method includes LPC tilt computation and compensation methods, a formant filter gain computation method, and an anti-aliasing method. The formant filter gain calculation utilizes an LPC representation, all-pole modeling, non-linear transformation, and phase computation. The LPC used for deriving the postfilter can be transmitted from an encoder or estimated from a synthesized speech signal in a decoder or receiver. This invention can be implemented in a linked decoder and encoder, with a separate LPC evaluation unit responsible for processing and deriving the LPC.
