On combining features for single-channel robust speech recognition in reverberant environments
José Novoa, Josué Fredes, Jorge Wuth +3
This paper addresses the combination of complementary parallel speech recognition systems to reduce the error rate of speech recognition systems operating in real highly-reverberan…
Highly-Reverberant Real Environment database: HRRE
Juan Pablo Escudero, Victor Poblete, José Novoa +5
Speech recognition in highly-reverberant real environments remains a major challenge. An evaluation dataset for this task is needed. This report describes the generation of the Hig…
Multichannel Robot Speech Recognition Database: MChRSR
José Novoa, Juan Pablo Escudero, Josué Fredes +3
In real human robot interaction (HRI) scenarios, speech recognition represents a major challenge due to robot noise, background noise and time-varying acoustic channel. This docume…
DNN-based uncertainty estimation for weighted DNN-HMM ASR
José Novoa, Josué Fredes, Néstor Becerra Yoma
In this paper, the uncertainty is defined as the mean square error between a given enhanced noisy observation vector and the corresponding clean one. Then, a DNN is trained by usin…
