Latest Patents

Juin-Hwey Chen holds a patent for a "Vector adaptive predictive coder for speech and audio." This invention describes a real-time vector adaptive predictive coder that approximates each vector of K speech samples by utilizing M fixed vectors in a first codebook. The technology excites a time-varying synthesis filter and selects the vector that minimizes distortion. Predictive analysis for each frame determines parameters used for computing zero-state response vectors stored at the same address in a second codebook. The encoding of input speech vectors is performed using this second codebook, and the index of the vector that minimizes distortion is transmitted to a decoder with an identical codebook. This innovative approach significantly enhances the synthesis of output speech vectors.
