Effect of compression ratio on perception of time compressed phonemically balanced words in Kannada and monosyllables

open access: yesAudiology Research, 2015
The present study attempted to study perception of time-compressed speech and the effect of compression ratio for phonemically balanced (PB) word lists in Kannada and monosyllables.

Image compression with anisotropic diffusion [PDF]

open access: yes, 2008
Compression is an important field of digital image processing where well-engineered methods with high performance exist. Partial differential equations (PDEs), however, have not much been explored in this context so far. In our paper we introduce a novel

Can Dual Compression Offer Better Mandarin Speech Intelligibility and Sound Quality Than Fast-Acting Compression?

open access: yesTrends in Hearing, 2021
The aim of this study was to evaluate the efficacy of dual compression for Mandarin-speaking hearing aid users. Dual compression combines fast and slow compressors operating simultaneously across all frequency channels.

Hyperspectral image compression : adapting SPIHT and EZW to Anisotropic 3-D Wavelet Coding [PDF]

open access: yes, 2008
Hyperspectral images present some specific characteristics that should be used by an efficient compression system. In compression, wavelets have shown a good adaptability to a wide range of data, while being of reasonable complexity.

Stochastic Optimization of Vector Quantization Methods in Application to Speech and Image Processing

open access: yes, 2023
Vector quantization (VQ) methods have been used in a wide range of applications for speech, image, and video data. While classic VQ methods often use expectation maximization, in this paper, we investigate the use of stochastic optimization employing our

Signal-to-Noise-Ratio-Aware Dynamic Range Compression in Hearing Aids

open access: yesTrends in Hearing, 2018
Fast-acting dynamic range compression is a level-dependent amplification scheme which aims to restore audibility for hearing-impaired listeners. However, when being applied to noisy speech at positive signal-to-noise ratios (SNRs), the gain function ...

Traditional Psychoacoustic Model and Daubechies Wavelets for Enhanced Speech Coder Performance

open access: yesInternational Journal of Technology, 2015
Speech compression techniques based on traditional psychoacoustic model have been proposed by many researchers. We have suggested Discrete Wavelet Transform (DWT) supported by the same psychoacoustic model for speech compression.
