Automatic Quality Estimation for ASR System Combination
Shahab Jalalvand, Matteo Negri, Daniele Falavigna +2
Recognizer Output Voting Error Reduction (ROVER) has been widely used for system combination in automatic speech recognition (ASR). In order to select the most appropriate words to…

DNN adaptation by automatic quality estimation of ASR hypotheses
Daniele Falavigna, Marco Matassoni, Shahab Jalalvand +2
In this paper we propose to exploit the automatic Quality Estimation (QE) of ASR hypotheses to perform the unsupervised adaptation of a deep neural network modeling acoustic probab…
