TLDR
We propose a system that, in addition to biasing the salience measure in favor of singing voice characteristics, acknowledges that the voice may not dominate the polyphony at all instants and therefore tracks an additional pitch to better deal with the potential presence of locally dominant pitched accompaniment.

Speech enhancement in nonstationary noise environments using noise properties
TLDR
We use spectral properties of the noise in order to detect noisy time–frequency regions which are then attenuated using a SNR-based rule. Expand
