Re: [AUDITORY] Why is it that joint speech-enhancement with ASR is not a popular research topic?

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).
