This paper firstly reports on the design of an audiovisual ‘face cover’ corpus. High-quality audio and video recordings were taken of 10 speakers reading phonetically-controlled stimuli under various face disguise conditions. Possible articulatory, acoustic and perceptual effects of the masks in a forensic context are introduced. Secondly, preliminary results of a spectral analysis of voiceless...

This paper presents an automatic music selection system based on runner’s step frequency. Recent development of portable music players like iPod has increased the number of those who listen to music while exercising. However, few systems which connect exercises with music selection have been developed. We propose a system that automatically selects music suitable for user’s running exercises. A...

In this paper, we describe a new method submitted to Mirex 2007 multiple fundamental frequency estimation contest.

The problem of sinusoidal frequency estimation in heavy-tailed noise environment is addressed. A method based on the robust M -periodogram is proposed. Specifically, a suboptimal coarse frequency estimate provided by the robust M -periodogram is improved using the modified dichotomous search. Simulations that consider most common heavytailed noise models demonstrate that the proposed method out...

In this paper we propose the MVDR method, which is based upon the Minimum Variance Distortionless Response (MVDR) spectrum estimation method, for modeling voiced speech. Developed to overcome some of the shortcomings of Linear Prediction models, the MVDR method provides better models for medium and high pitch voiced speech. The MVDR model is an all-pole model whose spectrum is easily obtained f...

Remote sensing has been used for direct and indirect detection of hydrocarbons. Most studies so far focused on indirect detection in vegetated areas. We investigated in this research the possibility of detecting hydrocarbons in bare soil through spectral analysis of laboratory samples in the short wave

The distribution of r-patterns is an important aspect of pseudorandomness for periodic sequences over finite field.The aim of this work is to study the distribution of r-patterns in the Kerdock-code binary sequences and the highest level sequences of primitive sequences over Z2l .By combining the local Weil bound with spectral analysis,we derive the upper bound of the deviation to uniform distr...

We present a study of two X-ray bursters in the Galactic Center field with the ART-P telescope onboard GRANAT. During 1990-1992 approximately 100 X-ray bursts were detected from the Galactic Center field and most of them were identified with the two persistent sources, A1742-294 and SLX1744-299/300. The burst recurrence times were found to be ∼ 2.4 and ∼ 4.6 hours, respectively, which is signif...
