Flego, F and Omologo, M (2006) Robust F0 estimation based on a multi-microphone periodicity function for distant-talking speech. European Signal Processing Conference. ISSN 2219-5491Full text not available from this repository.
This work addresses the problem of deriving F0 from distanttalking speech signals acquired by a microphone network. The method here proposed exploits the redundancy across the channels by jointly processing the different signals. To this purpose, a multi-microphone periodicity function is derived from the magnitude spectrum of all the channels. This function allows to estimate F0 reliably, even under reverberant conditions, without the need of any post-processing or smoothing technique. Experiments, conducted on real data, showed that the proposed frequency-domain algorithm is more suitable than other time-domain based ones.
