L1MFCC: original L1 utterances, resynthesized from MFCCs
L2MFCC: original L2 utterances, resynthesized from MFCCs
L2EMA: articulatory resynthesis of L1 utterances using DNNs
ACGMM: the articulatory-based foreing accent conversion using GMMs (baseline method)   
ACDNN: the articulatory-based foreign accent conversion using DNNs (proposed method)
L1GUISE: original L1 utterances, normalized to the vocal tract length and pitch range of L2
