Reversible Watermarking for Compressed Speech

2008 Eighth International Conference on Intelligent Systems Design and Applications, 2008
Reversible watermarking for compressed speech is proposed. Two properties of parameter-based speech coding bitstream are pointed out. Based on the properties, unimportant parameters are further compressed by entropy coding and concatenated with the watermark payload.

Distributed steganalysis of compressed speech

Soft Computing, 2015
In this paper, we present a distributed steganalysis scheme for compressed speech in voice-over-IP scenarios to provide fast and precise detection results. In this scheme, each speech parameter available for concealing information is designed to be detected independently exploiting the corresponding optimal detection feature.

Speech compression

Proceedings of the 20th annual Southeast regional conference on - ACM-SE 20, 1982
This paper presents research undertaken in the field of speech compression with a low cost speech processing system developed around an APPLE II microcomputer. Unlike some of the more popular techniques of speech compression based on statistical analysis of the speech waveforms in the frequency domain, speech compression was approached by the authors ...

Two-dimensional speech compression

ICASSP '78. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
The application of recent video data compression techniques to speech data is described. In order to effectively apply these techniques, the speech data should be segmented so as to achieve a high degree of correlation between corresponding samples in adjacent speech segments, allowing the formation of a two-dimensional speech "raster" with significant

Speech Analysis Technique for Speech Compression

i-manager's Journal on Software Engineering, 2011
This paper presents a comparison between the important transforms using in speech signal such as (Fast Fourier Transform, Discrete Wavelet Transform, Wavelet Packet Transform and Discrete Wavelet-Fast Fourier Transform) and try to compression the coefficients that received from any transforms by using zero's coder before using arithmetic coding ...

Comparing speech compression using wavelets with other speech compression schemes

Proceedings. Student Conference on Research and Development, 2003. SCORED 2003., 2005
Speech compression is one area of digital signal processing that focuses on reducing the bit rate of the speech signal for transmission or storage without significant loss of quality. In recent years a new technique called wavelet transform has been proposed for signal analysis. It has been successfully used in image compression application.

Time Compressed Speech—a Perspective

Journal of Communication, 1968
It has now been fifteen years since Garvey published the results of his laborious first attempt to study the effects of time-compressing speech. While there has not until recently been a very heavy investment in research in this area, we have now reached a time when we may ask what we have learned in the interim. What do we need to know?

The Optimal Wavelet for Speech Compression

2011
The main idea of speech compression is to reduce the bite rate of the speech for communication or storage without significant loss of quality. There are mainly three functional categories of speech processing methods in use. The new technique called wavelet transform is being used for speech signal analysis and synthesis. The major issues regarding the

Speech Compression and Recognition

2021
This chapter is devoted to intriguing topic of speech processing. We learn mechanisms of voice production and become familiar with our human speech synthesis system and its computer model. We recognize a very important role of vocal folds (cords) in excitation of our vocal tract with air flowing from the lungs.

Speech Compression and Synthesis

1980
Abstract : This report concludes our work for the past two years on speech compression and synthesis. A real-time variable-frame-rate LPC vocoder was implemented operating at an average rate of 2000 bits/s. We also tested our mixed-source model as part of the vocoder.
