Speech Signal Autoregression Modeling Based on the Discrete Fourier Transform and Scale-Invariant Measure of Information Discrimination
Journal of Communications Technology and Electronics. 2021. Vol. 66. No. 11. P. 1266-1273.
Savchenko V. V., Savchenko L.
In this paper, we consider the problem of autoregressive modeling of a speech signal according to the data of its discrete Fourier transform on intervals of one speech frame (several milliseconds). Based on the information-theoretic approach, a novel method, in which two computational procedures, namely, iterative optimization of autoregressive parameters and their automatic amplitude scaling are separated from each other was developed. A full-scale experiment was set up and carried out. The main advantage of the new method in comparison with its known analogs is shown to be the extremely high rate of convergence of iterations to the optimal solution.

Starting from the definition of the main tone of the speaker’s speech as the minimum frequency of
the linear power spectrum of the vocalized segments of the speech signal, an estimation of potentially achievable
accuracy of its measurement under the action of background interference such as white Gaussian noise
has been made. Based on this estimation, a suboptimal ...

We consider the problem of determination of the intelligibility of speech of a speaker according to a fi nite
fragment of the speech signal. It is shown that the main diffi culties in the solution of this problem are
connected with the necessity of analysis of small samples. To overcome the problem of small samples, we
proposed a ...

This paper studies the first differences w(t) of the International Sunspot Numbers daily series, ISSN, over the 1850-2013 time span. The one-day correlations r1 between w(t) and w(t+1) are computed within 4 year sliding windows and found to shift from negative to positive values near the end of Cycle 17. They remain positive during the ...

The present paper discusses the problem of distortions in speech signals transmitted over a communication channel to a biometric system during voice-based remote identification. A possible rectification approach involves a preliminary correction of the frequency spectrum of the received signal based on the pre-distortion principle. Taking into account a priori uncertainty, a new information indicator ...

We propose an algorithm for learning the Horn envelope of an arbitrary domain using an expert, or an oracle, capable of answering certain types of queries about this domain. Attribute exploration from formal concept analysis is a procedure that solves this problem, but the number of queries it may ask is exponential in the size ...

We formulate some term rewriting systems in which the number of computation steps is finite for each output, but this number cannot be bounded by a provably total computable function in Peano arithmetic PA. Thus, the termination of such systems is unprovable in PA. These systems are derived from an independent combinatorial result known as the Worm ...

This paper presents an algorithm for processing the transmission spectra of whisperinggallery optical microcavities for use as a nanoparticle detector. The algorithm is based on the broadening of the microcavity resonance curve during precipitation of nanoparticles on the microcavity surface. Experimental results on the detection of particles are compared with Langmuir adsorption theory. The contribution ...

Text encodings from automatic speech recognition (ASR) transcripts and audio representations have shown promise in speech emotion recognition (SER) ever since. Yet, it is challenging to explain the effect of each information stream on the SER systems. Further, more clarification is required for analysing the impact of ASR's word error rate (WER) on linguistic emotion ...

Work solutions are proposed for problems of leader definition and role distribution in homogeneous groups of robots. It is shown that transition from a swarm to a collective of robots with hierarchical organization is possible using exclusively local interaction. The local revoting algorithm is central to the procedure for choice of leader while redistribution of roles can ...
