Adaptive Sampling of Speech Signals
IEEE Transactions on Communications, 1974The present work gives a proposed method of sampling speech signals with a nonuniform sampling rate according to the magnitude of the slope of the signal, provided that the average sampling rate satisfies Shannon's requirements. With this proposed method, the quality of the reconstructed speech signal is improved.

The speech signal, as it emerges from a speaker’s mouth, nose and cheeks, is a one-dimensional function (air pressure) of time. Microphones convert the fluctuating air pressure into electrical signals, voltages or currents, in which form we usually deal with speech signals in speech processing.

This chapter provides a non-mathematical introduction to the speech signal. The production of speech is first described, including a survey of the categories into which speech sounds are grouped. This is followed by an account of some properties of human perception of sounds in general and of speech in particular.

Encoding and the rea for speech signals
Quarterly Journal of Experimental Psychology, 1971A number of different possible explanations are distinguished for the findings on the right ear advantage (REA) for speech signals varied in their acoustic and phonetic properties. Two experiments are reported, using synthesized semivowels and vowels in monosyllable word frames. Both show REA.

Digital Gating of Speech Signals
Language and Speech, 1976Temporal gating of speech signals by means of a digital computer offers many advantages over analogue gating techniques currently in use. Prior to digital processing the analogue speech signal has to be converted into its digital representation. Requirements on sampling rate, number of quantization levels, and frequency response of the smoothing filter

Monaural speech segregation using synthetic speech signals
The Journal of the Acoustical Society of America, 2006When listening to natural speech, listeners are fairly adept at using cues such as pitch, vocal tract length, prosody, and level differences to extract a target speech signal from an interfering speech masker. However, little is known about the cues that listeners might use to segregate synthetic speech signals that retain the intelligibility ...

Speech signal presentation to the totally deaf
Journal of Biomedical Engineering, 1983We have developed a system for single-channel electrical stimulation of the totally deaf. The patient wears a removeable electrode assembly which stimulates the cochlear promontory and can be inserted and removed like the earmould of a hearing aid.

Speech signal coding/decoding system based on the type of speech signal
The Journal of the Acoustical Society of America, 1993An input speech signal is encoded by an adaptive quantizer which quantizes the predicted residual signal between the digital input speech signal, and prediction signals provided by predictors and a shaped quantization noise provided by a noise shaping filter.
