Localization of multiple speakers based on a two step acoustic map analysis
An interface for distant-talking control of home devices requires the possibility of identifying the positions of multiple users. Acoustic maps, based either on Global Coherence F...

Fast speaker adaptation using non-negative matrix factorization
This paper describes a new method for fast speaker adaptation in large vocabulary recognition systems. As in most HMM-based recognizers, the observation densities are modeled as a...

HMM adaptation using a phase-sensitive acoustic distortion model for environment-robust speech recognition
In this paper, we present a new approach to HMM adaptation that jointly compensates for additive and convolutive acoustic distortion in environment-robust speech recognition. The ...
