Feature Mapping of Multiple Beamformed Sources for Robust Overlapping Speech Recognition Using a Microphone Array
Hervé Bourlard, John David Scott Dines, Weifeng Li
This paper introduces a non-linear vector-based feature mapping approach to extract robust features for au- tomatic speech recognition (ASR) of overlapping speech using a microphone array. We explore different configurations and additional sources of infor ...
Idiap2014Robust Log-Energy Estimation and its Dynamic Change Enhancement for In-car Speech Recognition
The log-energy parameter, typically derived from a full-band spectrum, is a critical feature commonly used in automatic speech recognition (ASR) systems. However, log-energy is difficult to estimate reliably in the presence of background noise. In this pap ...
Ieee-Inst Electrical Electronics Engineers Inc2013Adult Face Recognition in Score-Age-Quality Classification Space
Andrzej Drygajlo, Weifeng Li, Hui Qiu
Face verification in the simultaneous presence of age progression and changing face-image quality is an important problem that has not been widely addressed. In this paper, we study the problem by designing and evaluating a generalized Q-stack model, which ...
