An Evaluation of the Perceptual Quality of Phase-Aware Single-Channel Speech Enhancement
Audio examples
Below you find some examples of the audio files that have been used for the perceptual evaluation of phase-aware speech enhancement presented in the open access publication
The speech signals are taken from the TIMIT database, while the babble as well as the pink noise come from the NOISEX-92 database. To introduce some impulsive noise, we further added some hammer blows to the babble noise signal. Finally, we also tested a recording of a stroll in a park.
PBA (Phase-Blind Amplitude estimation) denotes Ephraim and Malah's short-time spectral amplitude estimator (STSA), which serves as a conventional, phase-blind reference. The estimated amplitude is combined with the noisy phase.
PAA (Phase-Aware Amplitude estimation) denotes the phase-aware amplitude estimator presented here. The estimated amplitude is combined with the noisy phase.
PAC (Phase-Aware estimation of Complex coefficients) denotes the case that the phase-aware amplitude estimate of PAA is combined with the clean speech phase. Please see the paper for details.
