Introduction

Hosana Kamiyama is a prominent inventor based in Yokosuka, Japan. He has made significant contributions to the field of paralinguistic information estimation, holding a total of 10 patents. His work focuses on enhancing the accuracy of paralinguistic information estimation, which is crucial for understanding nuances in spoken communication.

Latest Patents

Kamiyama's latest patents include a paralinguistic information estimation model learning apparatus and a paralinguistic information estimation apparatus. These inventions utilize advanced techniques to estimate paralinguistic information with high accuracy, even when the utterances are challenging to analyze. The acoustic feature extraction unit plays a vital role by extracting relevant acoustic features from the utterances. Additionally, the anti-teacher decision unit determines an anti-teacher label based on feedback from multiple listeners, which serves as a reference for incorrect paralinguistic information. The anti-teacher estimation model learning unit then learns to output a posterior probability of the anti-teacher for the input acoustic features.

Another notable invention is an estimation apparatus that clusters voice signals, including those with specific speaker attributes. This apparatus identifies the relevant cluster for a voice signal and estimates the speaker attributes based on the characteristics of the signals within that cluster. The estimation result provides valuable insights into the speaker attributes of the voice signal being analyzed.
