Latest Patents

One of his latest patents is a noise cancellation method designed for electronic devices. This method involves receiving an audio signal and applying a Fast Fourier Transform operation to generate a sound spectrum. It further includes acquiring a first spectrum corresponding to noise and a second spectrum corresponding to human voice signals. The method estimates a center frequency based on these spectrums and applies a high pass filtering operation accordingly.

Another significant patent is a voice processing method for use in communication apparatus. This method includes receiving a near-end audio signal through at least one microphone. It generates voice and noise energy data by performing voice activity detection on the audio signal. The method calculates the noise amount and determines if it exceeds a specified threshold. If it does, the communication apparatus enables a sidetone mode and a noise suppression mode to enhance audio clarity.
