Mean Hilbert envelope coefficients (MHEC) for robust speaker and language identification ?
Auditory robust feature for speaker and language identification (SID/LID). Employs Hilbert envelope of Gammatone filterbank outputs. Excellent performance in extreme noisy/channel conditions (DARPA RATS data). Power-law non-linearity gives consistent improvement for SID/LID tasks.
