Abstract:

In recent years, trained feature extraction (FE) schemes based on neural networks have replaced or complemented traditional approaches in top performing systems. This paper deals with FE in multilingual scenarios with a target language with low amount of transcribed data. Continuing our previous work on multilingual training of Stacked Bottle-Neck Neural Network FE schemes, we concentrate on improving the discriminatively trained Region-Dependent Transforms. We show that multilingual training of RDT can be implemented by merging statistics from several languages. In our case we used up to 11 source languages to build a FE which generalize well for a new language. This allows us to build a strong bootstrapping model for the final ASR system. The results are produced on IARPA Babel data.
