Native language identification from acoustic signals of L2 speakers can be useful in a range of applications such as informing automatic speech recognition (ASR), speaker recognition, and speech biometrics. In this paper we follow a multistream and multi-rate approach, for native language identification, in feature extraction, classification, and fusion. On the feature front we employ acoustic features such as MFCC and PLP features, at different time scales and different transformations; we… CONTINUE READING
