Testing with the YOHO CD-ROM voice verification corpus

Abstract

A standard database for testing voice verification systems, called YOHO, is now available from the Linguistic Data Consortium (LDC). The purpose of this database is to enable research, spark competition, and provide a means for comparative performance assessments between various voice verification systems. A test plan is presented for the suggested use of the LDC's YOHO CD-ROM for testing voice verification systems. This plan is based upon ITT's voice verification test methodology as described by Higgins, et al. (1992), but differs slightly in order to match the LDC's CD-ROM version of YOHO and to accommodate different systems. Test results of several algorithms using YOHO are also presented.
