Abstract

(ASR) systems for two domains in OpenSAT evaluations: LowResourced Languages and Public Safety Communications. Thefirst was challenging due to lack of training data, therefore multilingualapproaches for BLSTM training were employed andrecently published Residual Memory Networks requiring lesstraining data were used. Combination of both approaches led tosuperior performance. The second domain was challenging dueto recording in extreme conditions: specific channel, speakerunder stress, high levels of noise. A data augmentation processwas very important to get reasonably good performance.

Keywords
