Robust Pitch Tracking of Acoustic Signals based on Local Periodicity Index
نویسندگان
چکیده
In this paper, a method of pitch tracking based on variance minimization of locally periodic subsamples of an acoustic signal is presented. Replicates along the length of the periodically sampled data of the signal vector are taken and locally averaged sample variances are minimized to estimate the fundamental frequency. Using this method, pitch tracking of any text independent voiced signal is possible for different speakers over any database.

Perfect Tracking of Supercavitating Non-minimum Phase Vehicles Using a New Robust and Adaptive Parameter-optimal Iterative Learning Control
In this manuscript, a new method is proposed to provide a perfect tracking of the supercavitation system based on a new two-state model. The tracking of the pitch rate and angle of attack for fin and cavitator input is of the aim. The pitch rate of the supercavitation with respect to fin angle is found as a non-minimum phase behavior. This effect reduces the speed of command pitch rate. Control...

متن کاملPitch Tracking Based on Statistical Anticipation
An effective multi-pitch tracking algorithm for noisy speech is critical for auditory processing. However, the performance of existing algorithms is not satisfactory. We have developed a robust algorithm for multi-pitch tracking of noisy speech based on statistical anticipation. By combining an improved channel and peak selection method, a new integration method for extracting periodicity infor...
متن کاملAuditory modeling techniques for robust pitch extraction and noise reduction
A novel method for robust pitch extraction, based on the correlogram output of the Lyon’s cochlear model is described. The value of the autocorrelation lag for which the signals of the cochlear channels have the same periodicity can be computed thus tracking how the pitch of the input signal varies in the time domain. In the case of a stationary noise, a sort of ‘spectralsubtraction’ technique,...
متن کاملRobust Control of a Quadrotor
In this paper, a robust tracking control method for automatic take-off and trajectory tracking of a quadrotor helicopter is presented. The designed controller includes two parts: a position controller and an attitude controller. The attitude controller is designed by using the sliding mode control (SMC) method to track the desired pitch and roll angles, which are the output of position controll...
