Latest Patents

Satoru Goto holds a patent for a "Method and apparatus for estimating degree of similarity between voices." This patent describes a similarity degree estimation method that is performed through two processes. In the first process, an inter-band correlation matrix is created from spectral data of an input voice. The spectral data is divided into multiple discrete bands, which are separated by spaces along a frequency axis. Envelope components of the spectral data are obtained from these discrete bands, and the elements of the inter-band correlation matrix represent correlation values between the respective envelope components of the input voice. In the second process, a degree of similarity is calculated between a pair of input voices by using the respective inter-band correlation matrices obtained for the pair.
