multiple harmonically related sinusoidal components using a novel block sparse signal …

Instantaneous fundamental frequency estimation with optimal segmentation for nonstationary voiced speech

SM Nørholm, JR Jensen… - IEEE/ACM Transactions …, 2016 - ieeexplore.ieee.org
In speech processing, the speech is often considered stationary within segments of 20-30
ms even though it is well known not to be true. In this paper, we take the nonstationarity of …

An adaptive penalty multi-pitch estimator with self-regularization

F Elvander, T Kronvall, SI Adalbjörnsson, A Jakobsson - Signal Processing, 2016 - Elsevier
This work treats multi-pitch estimation, and in particular the common misclassification issue
wherein the pitch at half the true fundamental frequency, the sub-octave, is chosen instead …

Using optimal transport for estimating inharmonic pitch signals

F Elvander, SI Adalbjörnsson… - … , Speech and Signal …, 2017 - ieeexplore.ieee.org
In this work, we propose a novel multi-pitch estimation technique that is robust with respect
to the inharmonicity commonly occurring in many applications. The method does not require …
