Multi-stream spectro-temporal and cepstral features based on data-driven hierarchical phoneme clusters

We propose a method to enhance multi-stream Gabor and MFCC features using data-driven hierarchical phoneme clusters to yield more discriminating posteriors. We take into account different hierarchy structures, and in addition perform mean and variance
