Seq-2-Seq based Refinement of ASR Output for Spoken Name Capture
Karan Singla, Shahab Jalalvand, Yeon-Jun Kim +3
Person name capture from human speech is a difficult task in human-machine conversations. In this paper, we propose a novel approach to capture the person names from the caller utt…
Unsupervised Spoken Utterance Classification
Shahab Jalalvand, Srinivas Bangalore
An intelligent virtual assistant (IVA) enables effortless conversations in call routing through spoken utterance classification (SUC) which is a special form of spoken language und…
Automatic Data Expansion for Customer-care Spoken Language Understanding
Shahab Jalalvand, Andrej Ljolje, Srinivas Bangalore
Spoken language understanding (SLU) systems are widely used in handling of customer-care calls.A traditional SLU system consists of an acoustic model (AM) and a language model (LM)…
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…
