The currently dominant directon in ASR is "end-to-end learning". That is, to drop any hand-crafted feature extraction step from the processing chain, and let the deep learning algorithm solve the whole problem "as is". While many people doubt that this is the good direction (at least, with the current limited-capability learning algorithms), there is a strong pressure to prefer these end-to-end models over a two-step model (I mean enhancement+recognition).
