Query: Harmonic and non-Harmonic Based Noisy Reverberant Speech Enhancement in
  Time Domain   This paper introduces the single step time domain method named HnH-NRSE,
whihc is designed for simultaneous speech intelligibility and quality
improvement under noisy-reverberant conditions. In this solution, harmonic and
non-harmonic elements of speech are separated by applying zero-crossing and
energy criteria. An objective evaluation of the its non-stationarity degree is
further used for an adaptive gain to treat masking components. No prior
knowledge of speech statistics or room information is required for this
technique. Additionally, two combined solutions, IRMO and IRMN, are proposed as
composite methods for improvement on noisy-reverberant speech signals. The
proposed and baseline methods are evaluated considering two intelligibility and
three quality measures, applied for the objective prediction. The results show
that the proposed scheme leads to a higher intelligibility and quality
improvement when compared to competing methods in most scenarios. Additionally,
a perceptual intelligibility listening test is performed, which corroborates
with these results. Furthermore, the proposed HnH-NRSE solution attains SRMR
quality measure with similar results when compared to the composed IRMO and
IRMN techniques.
