By examining the relations among sections of the fundamental frequency contour used in judging an utterance as a question or statement, the experiment described in this report seeks a more detailed understanding of auditory-linguistic interaction in the perception of intonation contours. The perceptual process may be divided into stages (auditory,…

An experiment on sound waves, developed for non-science majors in a college physics course, is described. The student investigates the interference of two sound waves and measures and wavelength as he uses a prerecorded tape and a cassette player. The student is tutored by the cassette tape recorder, which also produces the overlapping sound…

This report, covering the period in 1976 from July 1 through September 30, is one of a regular series on the status and progress of speech research. Manuscript topics are: stop-consonant recognition--release bursts and formant transitions as functionally equivalent, context-dependent cues; modes of perceiving; discrimination of intensity…

This booklet, one of a series developed by the Frederick County Board of Education, Frederick, Maryland, provides an instruction module for an individualized or flexible approach to secondary science teaching. Subjects and activities in this series of booklets are designed to supplement a basic curriculum or to form a total curriculum, and relate…

Analyzes the physiological, acoustic, and auditory reasons for errors in the pronunciation of French nasal vowels by students, and suggests techniques for overcoming the difficulties identified. (AM)

Two experiments, a shadowing task and a mispronunciation-detection task, were performed to investigate the interactions between the data-driven primary speech perception process and the knowledge-driven word recognition process in the comprehension of continuous speech. Results are applied to an active direct access model of word recognition.…

This review examines the literature on auditory skills for evidence regarding the relationship of the sound blending skill and reading achievement. Factors that might affect this relationship are discussed. (Author/MV)

Identification of correctly produced and misarticulated /w,r,l,j/ was examined in 12 children, aged 3:6-7:5. The children, their parents, and raters were more successful in identifying correctly produced semivowels than misarticulated ones. Both normal children with developmental substitutions and articulation-impaired children demonstrated…

Tonal "flip-flop" (reversal of pitch value in which a direct exchange of value between two items is necessarily involved) can be found in a significant number of modern Chinese dialects, where an opposite pitch pattern is observed for the traditional Yin/Yang dichotomy of tones. (Author/CB)

This article explains how techniques of artificial intelligence are applied to expert systems for acoustic-phonetic decoding, phonological interpretation, and multi-knowledge sources for man-machine dialogue implementation. The basic ideas are illustrated with short examples. (Author/JDH)

Offers experiments and activities designed to help students understand the qualities of sound. Provides directives on how to construct simple musical instruments. Suggests ways to help students discriminate differences in pitch, dynamics, and rhythm. (ML)

Describes a microcomputer-based, multichannel digital data acquisition system for acoustic signals. Hardware and software considerations are included. (JN)

Materials needed and procedures for conducting two activities are provided. The first investigates drops of a liquid which float on water in a watchglass resting on top of a loudspeaker. The second investigates electromagnetic phenomena. (JN)

A door closes. A horn beeps. A crowd roars. Sound waves travel outward in all directions from the source. They can all be heard, but how? Did they travel directly to the ears? Perhaps they bounced off another object first or traveled through a different medium, changing speed along the way. Students learn how sound waves travel and about their…

While the new movement in the teaching of physics--the study of the physics of daily life--is the keynote of the recent text-books, yet the laboratory manuals still adhere to the old method, leaving the presentation of material from everyday life to the text-book alone. It is the authors' belief that the manual as well as the text-book should be…
