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?

Compressed Speech: Correlates of Listening Ability

Journal of Communication, 1968
To identify sources of individual differences in the ability to comprehend compressed speech, a battery of tests was administered to 52 college students. The criterion variable was performance on four multiple choice tests based on the content of four recorded history passages.

Speech Compression Overview

2009
Speech compression, also known as speech encoding or simply speech coding, means reducing the amount of data required to represent speech. Speech encoding is becoming increasingly vital for embedded systems that involve speech processing. This section will discuss general principles and types of speech encoding techniques, and briefly address the usage

Speech Compression Technique Using Compressive Sensing Theory

2017
This chapter presents the application of compressive sensing (CS) theory for compression of a speech signal. The speech signal is first converted into its sparse coefficients using a signal transform. Then compressed sparse measurements of the speech signal are generated using its sparse coefficients and a measurement matrix, generated using normal ...

Speech zero-crossing rate compression for bandwidth compression

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1975
As analysis performed on a proposed special purpose hearing aid yields data on single-sidebanded voice zero-crossing rates extracted by a phase-locked loop (PLL), and also data on the logarithmically compressed voltage analog of the zero-crossing rate.

Speech compression CODIMEX system

IEEE Transactions on Audio, 1963
A relatively simple installation is sufficient to obtain a four-to-one reduction of the frequency bandwidth occupied by a telephonic signal. The speech is decomposed into its three principal formants which constitute the basic information carrying elements.

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.

Design Examples—Speech Compression

1986
This last chapter is devoted entirely to the illustration, in the field of speech compression, of the theory developed in the previous chapters. We would like to emphasize that the results to be presented shortly are only of illustrative value and are not intended, in their present form, to be recommendations for practical consumption.

Stutterers' Perception of Time-Compressed Speech

Perceptual and Motor Skills, 1971
This study represents an attempt to test the hypothesis (derived from the motor theory of speech perception) that persons who have stuttered for many years will be less facile than nonstutterers at decoding time-compressed speech. 4 stutterers and 4 nonstutterers answered questions and rewrote paragraphs and sentences presented at various rates of ...
