In this paper we address the problem of speaker adaptation in noisy environments. We estimate speaker adapted models from noisy data by combining unsuper-vised speaker adaptation with noise compensation. We aim at using the resulting speaker adapted models in environments that differ from the adaptation environment, without a significant loss in(More)
This paper presents experiments of noise robust ASR on the Au-rora4 database. The database is designed to test large vocabulary systems in presence of noise and channel distortions. A number of different model-based and signal-based noise robustness techniques have been tested. Results show that it is difficult to design a technique that is superior in(More)
This paper presents a generalized feature projection scheme which allows each feature dimension to be classified in a set of 1 to M classes, where M is the total number of classes. Our method is an extension of the classical full-space null-space approach where each dimension can only be classified in either M classes or 1 class. We believe that this more(More)
We demonstrate a new platform for holographic interactive 3D experience. New user experience includes holographic 3D visual and audio experience, natural free-space 3D interaction, and augmenting the interface of smaller devices (e.g. smartphones). The head tracking component is compact and non-intrusive to 3D glasses' appearance. Depth sensor based 3D hand(More)
