Title: Innovations by Jianming Song
Introduction
Jianming Song is a notable inventor based in Barrington, IL (US). He holds a total of 13 patents that showcase his contributions to the field of audio signal processing and noise reduction technologies. His work has significantly impacted various industries, particularly in automotive and telecommunications.
Latest Patents
Among his latest patents is a method and apparatus for wind noise attenuation. This invention describes approaches for detecting and reducing wind noise from audio signals captured at a multi-microphone array. The wind noise detector is constructed from probabilities of speech presence and wind noise presence, derived from statistics of the phase differences among the time-aligned signals of multi-microphones in separate frequency regions. If wind noise is detected, it is reduced by a gain in the frequency domain, which is also a function of the phase difference and its statistics. Another significant patent focuses on robust noise estimation for speech enhancement in variable noise conditions. This invention improves speech in a motor vehicle by suppressing transient, 'non-stationary' noise using pattern matching. Pre-stored sets of linear predictive coefficients are compared to LPC coefficients of a noise signal, allowing for effective noise suppression.
