Normal-to-shouted speech spectral mapping for speaker recognition under vocal effort mismatch

ICASSP 2017accepted

Speaker recognition performance degrades substantially in case of vocal effort mismatch (e.g. shouted vs. normal speech) between test and enrollment utterances. Such a mismatch is often encountered, for example, in forensic speaker recognition. This paper introduces a novel spectral mapping method w…

Designing multichannel source separation based on single-channel source separation

ICASSP 2015accepted

In this paper, an extension of independent vector analysis (IVA), model-based IVA, is proposed for multichannel source separation. For obtaining better source models, we introduce a single-channel source separation method, and utilize the outputs as source variances in time-frequency-variant Gaussia…
