Title:
METHOD AND DEVICE FOR TRANSFORMING FEATURE VECTOR FOR USER RECOGNITION
Document Type and Number:
WIPO Patent Application WO/2016/137042
Kind Code:
A1
Abstract:
Disclosed is a method for transforming a feature vector, comprising: extracting a feature sequence from an audio signal comprising a user's phonation; extracting a feature vector from the extracted feature sequence; obtaining, on the basis of probability values based on different covariance values, a transformation matrix for reducing the number of dimensions of the extracted feature vector; and transforming the feature vector using the transformation matrix.
