Single-channel speech presence probability estimation using inter-frame and inter-band correlations
2014
2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
The speech presence probability (SPP) plays an important role in many noise reduction and noise estimation methods. The SPP is commonly computed per time and frequency in the short time Fourier transform (STFT) domain based on the a priori speech absence probability and the a priori and a posteriori signal-tonoise ratios. Due to the STFT as well as the nature of the speech signal, there exists a correlation between subsequent time frames and neighboring frequency bands. In this work, we
