Abstract
This article describes the novel things we have brought to our BABEL Cantonese system include 6-layer Stacked Bottle-Neck features and using f0 at the input of this NN. We have also investigated into robustness of SBN training (silence, normalization) and shown an efficient combination with PLP and (again!) F0 features using Region-Dependent transforms. Last by not least, a combination of RDT with another popular adaptation technique (SAT) was shown beneficial.
Annotation
This paper presents our work on speech recognition of Cantonese spontaneous telephone conversations. The key-points include feature extraction by 6-layer Stacked Bottle-Neck neural network and using fundamental frequency information at its input. We have also investigated into robustness of SBN training (silence, normalization) and shown an efficient combination with PLP using Region-Dependent transforms. A combination of RDT with another popular adaptation technique (SAT) was shown beneficial. The results are reported on BABEL Cantonese data.
