SUNNYVALE, Calif.--(BUSINESS WIRE)--Alt, Inc. which has developed ”al+”, the Personal Artificial Intelligence (P.A.I.) (Headquarters: Koto-ku, Tokyo, CEO, Mr. Kazutaka Yonekura) has begun a joint research on voice-cloning with Associate Professor Junichi Yamagishi of the National Institute of Informatics (hereafter known as “NII”).
Alt believes that in the development of P.A.I., it is equally essential to study about outer appearance of human beings just like the thinking and communication function. The human voice is a very important element to establish the identity of its owner.
The voice synthesis technology which Yamagishi is studying reproduces unique audio characteristics of a person’s voice by measuring the difference from derived mean value of a large human voice sample collection. While a vast amount of voice recordings is required in the conventional synthetic speech generation in order to train the computer to learn the unique characteristics of a speaker’s voice, high precision voice-cloning is made possible using a small amount of voice recordings with the application of Yamagishi's technology.
In this joint research, we will be conducting research and development to integrate the P.A.I. which Alt is developing and Yamagishi’s voice-cloning technology, to create a system which automatically generates advanced cloned avatars. Further, the said acoustic model will be applied to a large number of users simultaneously, to build a system which can generate a large amount of voice clones in a short period of time.
