Discusses the efforts of researchers to answer the question: "What is music?". (GB)

The acoustics of speech production allows the prediction of resonances for a given vocal tract configuration. Combining these predictions with aerodynamic theory developed for mechanical whistles makes theories about human whistling more complete. Several experiments involving human whistling are reported which support the theory and indicate new…

This book is written as a guide to the understanding of the processes involved in human speech communication. Ten authorities contributed material to provide an introduction to the physiological aspects of speech production and reception, the acoustical aspects of speech production and transmission, the psychophysics of sound reception, the nature…

Using acoustical evidence from spectrograms and physiological evidence from X-ray sound films, it appears that the most common allophone for the Arabic voiced pharyngeal fricative, at least in Iraqi, is a voiceless stop, and not a voiced fricative, as many believe. The author considers the phoneme in different environments and describes its…

Electroglottographic (EGG) and acoustic waveforms of the first few glottal pulses of voicing were monitored and voice onset time (VOT) measured during an adaptation task performed by adult stutterers and controls. Fluent utterances of stutterers resembled those of controls. After dysfluencies, however, the EGG signal increased gradually, lending…

Acoustic analysis of the oral reading of 36 10- to 12-year-olds was performed to examine the relationship between selected acoustic characteristics and listener judgements of the Ss' vocal effectiveness. Results revealed variability of speaking time, pause time, and phonation-time ratio among Ss and between two trials. (Author/CL)

An acoustic-phonetic study of six Vietnamese tones was carried out on approximately 3000 sound spectrograms of four native speakers of the Hanoi dialect. Three temporal segments, four pitch levels, and glottalization were identified as important cues for tone recognition. (Author/FWB)

This technical paper analyzes the primary level of rhythm in English verse: that created by the numerical, sequential, and temporal patterns of the sounds of syllables and silences. (AN)

Investigates the effects of acoustic similarity on memory span in 112 children four to 10 years of age. Acoustic similarity had progressively more effect on recall with increasing age. Implications for current theories of short-term memory and its development and for the use of acoustic similarity as an indicator of speech coding are discussed.…

Thirty infants from monolingual Spanish-speaking homes were tested for discrimination of bilabial stop consonants differing in voice onset time (VOT). Discrimination was determined by the habituation and dishabituation of the orienting reflex as indexed by cardiac deceleration. (Author/GO)

Results of research to limit or expand identification of vowel frequency bands show that [i], [a], and [u] sounds are highly recognizable when filtered through a single frequency zone, but that other vowels under the same conditions are less easily recognized than those obtained by the direct channel. (Author/MSE)

A study was conducted of five individuals exhibiting acquired apraxia of speech to examine vowel durations and length of intervals between words produced in utterances that varied in type of utterance as well as in length. Results found evidence that longer vowel durations were a salient characteristic of apraxia of speech. (CR)

Evaluates "mean response time" (MRT), a method used in previous studies to relate physiological evidence (recordings of electromyographic activity in the cricothyroid and sternohyoid) to acoustic evidence (fundamental frequency). (Author/VWL)
