About speech data compression [PDF]

, 2017
The continuous increase of voice message flow in the information and telecommunications systems (ITS), as the most natural form of information exchange for a person, led to the almost full occupation of the time-frequency resources of modern ITS. In this

Speech Spectral Quantizers for Wideband Speech Coding

, 2001
. In this treatise a range of Line Spectrum Frequency (LSF) Vector Quantization (VQ) schemes were studied comparatively, which were designed for wideband speech codecs. Both predictive arrangements and memoryless schemes were investigated.

A new speech compression method

, 2004
In this paper a new speech compression method is presented. The traditional speech compression method is based on linear prediction. The compression method, proposed in this paper, is based on the use of an orthogonal transform, the discrete cosine ...

Auditory perceptual efficacy of nonlinear frequency compression used in hearing aids: A review

Journal of Otology, 2017
Many patients with sensorineural hearing loss have a precipitous high-frequency loss with relatively good thresholds in the low frequencies. This present paper briefly introduces and compares the basic principles of four types of frequency lowering ...

In-Band Disparity Compensation for Multiview Image Compression and View Synthesis [PDF]

, 2010
This paper presents a novel framework to achieve scalable multiview image compression and view synthesis. The open-loop wavelet-lifting scheme for geometric filtering has been exploited to achieve signal-to-noise ratio scalability and view-type ...

Language form compression in modern Russian speech

Russian Language Studies
Compressive word formation results from the active tendency to save speech effort and, accordingly, to save linguistic means, which makes its research relevant.

Steganalysis of compressed speech to detect covert voice over Internet protocol channels [PDF]

, 2011
A network covert channel is a passage along which information leaks across the network in violation of security policy in a completely undetectable manner. This study reveals our findings in analysing the principle of G.723.1 codec that there are `unused'
