Bayesian Distance Metric Learning on i-vector for Speaker Verification
i-vector score normalization distance metric learning channel compensation limited training utterances
2014/11/27
This paper presents a new speaker verification system based on i-vector modeling as a feature extractor. In this modeling, we explore the distance constraints between i-vector pairs from the same spea...
