Speech Compression and Recognition
2021This 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.

The potential for compressed speech in medical education
Proceedings of the 15th annual Southeast regional conference on - ACM-SE 15, 1977New technical information was presented to a medical school class divided into five groups. Group I served as controls and took the pretest before having any input. Groups II - V listened to slide-tapes presented at varying rates of speed from 114 (natural) to 250 words per minute (WPM).

Speech Compression and Synthesis
1980Abstract : 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.

Two dimensional data compression of speech
ICASSP '78. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005Speech signal is considered as a two dimensional pseudo-image by segmenting it into blocks of N sample points. Successive segments are placed adjacently thereby forming a sequence of columns or a two dimensional image. Image data compression techniques can now be applied to exploit inter-segment redundancies.

Multistep coding of speech parameters for compression
IEEE Transactions on Speech and Audio Processing, 1998This paper presents specific new techniques for coding of speech representations and a new general approach to coding for compression that directly utilizes the multidimensional nature of the input data. Many methods of speech analysis yield a two-dimensional (2-D) pattern, with time as one of the dimensions.

Intelligibility of time-compressed speech: three ways of time-compression
6th International Conference on Spoken Language Processing (ICSLP 2000), 2000Studies on fast speech have shown that word-level timing of fast speech differs from that of normal rate speech in that unstressed syllables are shortened more than stressed syllables as speech rate increases. An earlier experiment showed that the intelligibility of time-compressed speech could not be improved by making its temporal organisation closer

Compressive speech enhancement in the modulation domain
Speech Communication, 2018Abstract Compressive speech enhancement (CSE) has gained popularity in recent years as it bypasses the need for noise estimation. Parallel to that, modulation domain has been widely studied in speech applications as it offers a more compact representation and is closely associated with speech intelligibility enhancement.

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
