Title: Changbao Zhu: Innovator in Speech Recognition Technology
Introduction
Changbao Zhu is a prominent inventor based in Nanjing, China. He has made significant contributions to the field of speech recognition technology, holding three patents that showcase his innovative approach to solving complex problems in noisy environments.
Latest Patents
One of his latest patents is titled "Method and apparatus for multiway speech recognition in noise." This invention discloses a method and apparatus for recognizing speech by separating an input audio signal into at least two separated signals. The method generates a denoised signal at a current frame and performs preliminary recognition on each interesting signal at that frame. A recognition decision is made based on the recognition score of each interesting signal, allowing for a high recognition rate even in low signal-to-noise ratio conditions.
Another notable patent is the "Method and apparatus for reducing noise of mixed signal." This invention involves separating a collected mixed signal to obtain a first signal and a second signal. The method selects one of these signals as a current reference signal and the other as a current expected signal. Adaptive filtering is then performed based on the selected signals, significantly reducing or removing noise when a reference signal cannot be directly obtained from hardware.
