摘要:

本文介绍了BUT自动语音识别(ASR)系统提交的OpenSAT评估两个领域的类别,如低资源的语言和公共安全通信。由于缺乏训练数据,第一个是具有挑战性的,因此采用了各种架构和多语言方法。这种组合带来了卓越的性能。第二个领域是具有挑战性的,由于在极端条件下录制,如特定的通道,扬声器压力和高水平的噪音。数据扩充过程是不可避免的,以获得合理的良好性能。

英文摘要:

The paper describes the BUT Automatic Speech Recognition (ASR) systems submitted for OpenSAT evaluations under two domain categories such as low resourced languages and public safety communications. The first was challenging due to lack of training data, therefore various architectures and multilingual approaches were employed. The combination led to superior performance. The second domain was challenging due to recording in extreme conditions such as specific channel, speaker under stress and high levels of noise. Data augmentation process was inevitable to get reasonably good performance.
