On recognition of non-native speech using probabilistic lexical model

Marzieh Razavi, Mathew Magimai Doss
2014 Interspeech 2014   unpublished
In this paper, we investigate the role of different factors such as type of lexical model and choice of acoustic units in recognition of speech uttered by non-native speakers.  ...  Despite various advances in automatic speech recognition (ASR) technology, recognition of speech uttered by non-native speakers is still a challenging problem.  ...  Discussion and Conclusion In this paper, we studied the role of the probabilistic lexical model in the KL-HMM framework in improving non-native speech recognition without using any adaptation data.  ...

On modeling context-dependent clustered states: Comparing HMM/GMM, hybrid HMM/ANN and KL-HMM approaches

Marzieh Razavi, Ramya Rasipuram, Mathew Magimai-Doss
2014 2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)  
Index Terms-HMM/GMM, hybrid HMM/ANN, Kullback-Leibler divergence based HMM, context-dependent subword units, non-native speech recognition  ...  The reduction in number of clustered states has broader implications on model complexity and data sparsity issues.  ...  WER on native speech decreases. On the other hand, as number of acoustic states is increased, the WER on non-native speech eventually increases for all the three systems.  ...

Pre-lexical abstraction of speech in the auditory cortex

Jonas Obleser, Frank Eisner
2009 Trends in Cognitive Sciences  
According to most cognitive models of spoken word recognition, this complexity is dealt with before lexical access via a process of abstraction from the acoustic signal to pre-lexical categories.  ...  Recent advances in animal neurophysiology and human functional imaging have made it possible to investigate the processing of speech in terms of probabilistic cortical maps rather than simple cognitive  ...  Acknowledgements J.O. is employed by the Max Planck Society, Germany, and received additional funding from the Landesstiftung Baden-Wü rttemberg gGmbH during initial phases of this project.  ...
