Title: Kazunori Mano: Innovator in Speech Encoding Technology

Introduction

Kazunori Mano is a prominent inventor based in Musashino, Japan. He has made significant contributions to the field of speech encoding technology, holding a total of 16 patents. His work focuses on improving the quality of decoded speech, making it more natural and audible for users.

Latest Patents

Among his latest patents are the "Fixed sound source vector generation method" and "Fixed sound source codebook." In the first patent, a method is described for generating a fixed excitation vector at the speech encoding end. This involves identifying the shape of an excitation vector output from a pulse excitation codebook. A dispersion vector, used for excitation vectors of the identified shape, is then output from a storage unit. The dispersion vector convolution processor performs convolution processing of the excitation vector. This technology enhances the quality of decoded speech, making it more natural and audible to users.

Another notable patent is the "Speech decoder that detects stationary noise signal regions." This invention includes a first determiner that tentatively assesses whether the current processing unit represents a stationary noise period based on the stationary properties of a decoded signal. A second determiner then confirms this assessment, distinguishing between stationary speech signals and stationary noise, thereby accurately identifying stationary noise periods.
