Title: The Innovations of Gou Hirabayashi

Introduction

Gou Hirabayashi is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of speech synthesis, holding a total of 4 patents. His work focuses on enhancing the technology behind speech synthesis systems, making them more efficient and user-friendly.

Latest Patents

Hirabayashi's latest patents include a speech synthesis dictionary delivery device, a speech synthesis system, and a program storage medium. The speech synthesis dictionary delivery device is designed to deliver a dictionary for performing speech synthesis to terminals. It comprises a storage device for a speech synthesis dictionary database that stores a first dictionary, which includes an acoustic model of a speaker and is associated with identification information of the speaker. Additionally, it stores a second dictionary that includes an acoustic model generated using voice data from multiple speakers, along with parameter sets of the speakers associated with their identification information. The processor within the device determines which dictionary should be used for a specified speaker, while the input-output interface receives the speaker's identification information and delivers the appropriate dictionary or parameter set based on this information.

Another innovative method developed by Hirabayashi involves storing a representative speech unit waveform for speech synthesis. This method generates speech information from text, which includes phonologic and prosody information. It divides the speech information into multiple speech units based on this information and searches for similar speech units. The method then stores a speech unit waveform corresponding to one of the similar speech units as a representative speech unit in memory.
