【発明の名称】不明人物の同一性検証方法
Document Type and Number:
Japanese Patent JP3080388
Kind Code:
B2
Abstract:
A speaker verification system receives input speech from a speaker of unknown identity. The speech (12, 14) undergoes LPC analysis and trangformation to maximize separability between true speakers and impostors when compared (16) to reference speech parameters which have been similarly transformed. The transformation incorporated a "inter-class" covariance matrix of successful impostors within a database.
