Title: Innovations by Harald Hoege
Introduction
Harald Hoege is a notable inventor based in Gauting, Germany. He has made significant contributions to the field of technology, particularly in the areas of speech recognition and data compression. With a total of 3 patents to his name, Hoege continues to push the boundaries of innovation.
Latest Patents
One of Hoege's latest patents is focused on compressing HMM (Hidden Markov Model) prototypes. This method describes how to reduce the storage space required for HMM prototypes in electronic memory. By utilizing a neural network as an encoder, prescribed HMM prototypes are mapped onto compressed versions, allowing for more efficient storage. A second neural network, acting as a decoder, reconstructs the original HMM prototypes from the compressed data.
Another significant patent involves an echo suppressor designed for speech input dialogue systems. This technology is particularly effective in systems with long echo paths, approximately 50 ms. The method involves fast-Fourier transforming both the input request and the incoming speech signal, which has been affected by the input request. The transformed signals are divided into sub-bands to estimate corresponding echo signals using individual adaptive filter stages that employ the NLMS algorithm. This approach minimizes computational load and reduces the sampling rate, ultimately restoring the original speech signal by subtracting the estimated echo components.
