Speech compression algorithm based on non-equidistant sampling
Communications, 2004 The method presented here is one of the methods of time domain compression. The technique uses non-equidistant sampling. Human voice and voice conversation are characterized by transitions.

FST-Based Pronunciation Lexicon Compression for Speech Engines
International Journal of Advanced Robotic Systems, 2012 Finite-state transducers are frequently used for pronunciation lexicon representations in speech engines, in which memory and processing resources are scarce. This paper proposes two possibilities for further reducing the memory footprint of finite-state

A Multiband Excited Waveform-Interpolated 2.35-kbps Speech Codec for Bandlimited Channels
, 2000 Following a brief portrayal of the activities in 2.4-kbps speech coding, a wavelet-based pitch detector is invoked, which reduces the complexity of conventional autocorrelation-based pitch detectors, while ensuring smooth pitch trajectory evolution. This

Effects of Instantaneous Multiband Dynamic Compression on Speech Intelligibility
EURASIP Journal on Advances in Signal Processing, 2005 The recruitment phenomenon, that is, the reduced dynamic range between threshold and uncomfortable level, is attributed to the loss of instantaneous dynamic compression on the basilar membrane. Despite this, hearing aids commonly use slow-acting dynamic

, 2005 —since the different bits of multimedia information, such as speech and video, have different error sensitivity, efficient unequalprotection channel coding schemes have to be used to ensure that the perceptually more important bits benefit from more ...

An LPC Excitation Model using Wavelets
ITB Journal of Engineering Science, 2008 This paper presents a new model of linear predictive coding (LPC) excitation using wavelets for speech signals. The LPC excitation becomes a linear combination of a set of self- similar, orthonormal, band-pass signals with time localization and constant
