TL;DR: Fairbanks' speech time‐adjusting device has been simulated, using a hybrid computer, and a dichotic method for time compression of speech was investigated, suggesting that speech compressed with the dichotics method may be more intelligible thanspeech compressed with Fairbanks' method.
Abstract: Fairbanks' speech time‐adjusting device has been simulated, using a hybrid computer. This device discards or repeats recorded speech segments to compress or expand the time dimension. A dichotic method for time compression of speech was investigated in which odd‐numbered time segments were presented to one ear and even‐numbered segments to the other ear. A preference test suggested that speech compressed with the dichotic method may be more intelligible than speech compressed with Fairbanks' method. Potential applications for time‐adjusted speech and possibilities for further research are suggested.

TL;DR: In some communications systems, the need arises for temporally interpolating data or signalling information during continuous speech to fill the required time gaps created by simply interrupting the speech signal.
Abstract: In some communications systems, the need arises for temporally interpolating data or signalling information during continuous speech1 If the required time gaps are created by simply interrupting the speech signal, severe degradation of speech quality and some loss in intelligibility results

TL;DR: There are many applications for the speech analyzer and synthesizer ranging from limited vocabulary to complete communication systems.
Abstract: The processing of speech involves the analysis, coding, decoding, and synthesis of speech sounds. The speech analyzer consists of normalizers, syllable and syblet segmenters, sound recognizers, sequencers, adapters, and memories which convert the speech elements into a code. The speech synthesizer converts the code to speech by reproducing prerecorded speech elements. There are many applications for the speech analyzer and synthesizer ranging from limited vocabulary to complete communication systems.

TL;DR: In the process of hearing, the human ear develops a short-time spectrum of its acoustic input and information-bearing features of the signal are retained in this spectral analysis.
Abstract: In the process of hearing, the human ear develops a short-time spectrum of its acoustic input. Information-bearing features of the signal are retained in this spectral analysis. An understanding of the process by which the human auditory system preserves perceptually significant features is valuable in developing speech-transmission techniques. An example of effort in this direction is the phase vocoder.
