| Abstract(in English) | This paper presents the ATR speech recognition system designed for the DARPA SPINE2 evaluation task. The system is capable of dealing with speech from highly variable, real world noisy conditions and communication channels. A number of robust techniques were implemented, such as differential spectrum mel-scale cepstrum features, on-line MLLR adaptation and word level hypothesis combination, which led to significant reduction of the word error rate. |
