The paper provides an analysis of automatic speech recognitionsystems (ASR) based on multilingual BLSTM, where weused multi-task training with separate classification layer foreach language. The focus is on low resource languages, whereonly a limited amount of transcribed speech is available. Insuch scenario, we found it essential to train the ASR systemsin a multilingual fashion and we report superior resultsobtained with pre-trained multilingual BLSTM on this task.The high resource languages are also taken into account andwe show the importance of language richness for multilingualtraining. Next, we present the performance of this techniqueas a function of amount of target language data. The importanceof including context information into BLSTM multilingualsystems is also stressed, and we report increased resilienceof large NNs to overtraining in case of multi-tasktraining.
