| Abstract(in English) | Speech recognition technical is becoming popular in many fields, while the acoustic model for native is not effective for non-native speakers. Thus, we need to distinguish the accent of native and non-native speech and select the appropriate acoustic model for speech recognition. In this paper, we consider the effect of reverberation in reality application. Thus, two methods of accent verification by using GMM and DNN in reverberant environment are proposed. The combination of likelihood with these two approaches is also performed. In reverberant environment, we improved the accent verification rate from 49.9% to 90.7% with GMM and 90.4% with DNN. Furthermore, the combination of likelihood gives a better verification rate of 96.6%. |
