Latest Patents

One of his latest patents is the "Harmonic-noise speech coding algorithm and coder using cepstrum analysis method." This invention relates to a harmonic-noise speech coder that effectively codes the mixed signal of voiced and unvoiced sounds using a harmonic model. The coder includes a noise spectral estimating means that predicts the spectral by LPC analysis after separating the noise component from the inputted LPC residual signal using cepstrum. This method enhances speech quality by analyzing noise effectively through a noise spectral model predicted via cepstrum-LPC analysis.

Another significant patent is the "Speech coding system and method using time-separated coding algorithm." This invention features a time-separated speech coder that codes transitional signals of voiced and unvoiced sounds through harmonic speech coding. The coder includes a transitional excitation signal analyzer/synthesizer that extracts harmonic model parameters after detecting a transitional point. This innovative approach results in improved speech quality by increasing the representation capability of transitional signals with large energy variations.
