Title: Satoshi Miki: Innovator in Speech Coding Technologies
Introduction
Satoshi Miki is a prominent inventor based in Tokorozawa, Japan. He has made significant contributions to the field of speech coding, holding a total of 4 patents. His work focuses on innovative methods that enhance the quality and efficiency of speech data processing.
Latest Patents
Miki's latest patents include groundbreaking technologies such as "Speech coding by code-edited linear prediction." This method involves analyzing speech data samples through linear prediction analysis to calculate prediction coefficients. These coefficients are then quantized and utilized in a synthesis filter. Additionally, a pitch period vector is selected from an adaptive codebook, which is multiplied by a first gain. A noise waveform vector is also selected from a random codebook and processed similarly. This synthesis process results in coded speech data that is efficient and high-quality.
Another notable patent is the "Method for the modification of LPC coefficients of acoustic signals." In this innovation, p-order LPC coefficients of an input signal are transformed into n-order LPC cepstrum coefficients. These coefficients are modified and then inversely transformed into m-order LPC coefficients for use in perceptual weighting filters. This method enhances the quality of acoustic signal processing.
