Title: Innovations by Heng Liu in Automatic Speech Recognition

Introduction

Heng Liu is an accomplished inventor based in Tucson, AZ, known for his significant contributions to the field of automatic speech recognition. With a total of three patents to his name, Liu has developed innovative systems and methods that enhance the efficiency and accuracy of speech recognition technologies.

Latest Patents

Liu's latest patents include groundbreaking work in systems and methods for accelerating automatic speech recognition based on compression and decompression. This method involves processing a series of acoustic signals to create a padded sequence, which is then compressed to reduce its size. The compressed sequence is input into a pre-trained encoder neural network, resulting in an encoded sequence that is subsequently decompressed to recover the original sequential ordering. Finally, the encoded sequence is processed through a decoding module to generate recognition texts.

Another notable patent focuses on automatic speech recognition systems utilizing graphics processing units. This system comprises an encoder and a decoder, with the encoder featuring multiple layers that include fused encoder sublayers. The decoder, similarly structured, receives outputs related to the encoder and generates corresponding decoder outputs. This innovative approach significantly enhances the performance of speech recognition systems.
