Tonal languages differ in how they use phonetic correlates, e.g. average pitch height and pitch direction, for tonal contrasts. Thus, native speakers of a tonal language may need to adjust their attention to familiar or unfamiliar phonetic cues when perceiving non-native tones. On the other hand, speakers of a non-tonal language may need to…

Certain ill-formed phonological structures are systematically under-represented across languages and misidentified by human listeners. It is currently unclear whether this results from grammatical phonological knowledge that actively recodes ill-formed structures, or from difficulty with their phonetic encoding. To examine this question, we gauge…

Are speakers equipped with preferences concerning grammatical structures that are absent in their language? We examine this question by investigating the sensitivity of English speakers to the sonority of onset clusters. Linguistic research suggests that certain onset clusters are universally preferred (e.g., "bd" is greater than "lb"). We…

To determine to what extent listeners respond to the vocal content of "how" of spoken messages, this study investigated the effects that the two vocal variables or rate (speed) and intensity (loudness) had on the responses made by 445 English-speaking high school students to messages spoken in an unfamiliar tongue. The basic messages were recorded…

Two experiments are reported which explore (1) into what categories do native listeners divide the perceived pitch contours of their language; (2) into what perceptual units can these overall contour structures be further broken down; and (3) what is the range of tolerance for each unit? (Author/RM)

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,…

The experiments described in this report seek to investigate the characteristics of speech perception using an approach which considers the development of the perception of "voicing," both as it occurs naturally and as it might occur in the laboratory. Investigating voicing discrimination and perception training among adults, infants, and…

Recent research in experimental phonetics seems to provide evidence for a clear division between language units and speech units. Many researchers have suggested that the consonant-vowel (CV) syllable may be a universal unit of speech production and perception, while language units become criterial only at higher levels of processing. In second…

This article provides a discussion of current topics in psycholinguistics and of the current research on these problems. The author discusses current thought on the biological foundations of language and the problem of universals. If human language is a species-particular achievement contingent upon a biological endowment, there should be certain…

The idea that vowel nuclei in many northern European languages can be divided into peripheral and non-peripheral categories is discussed. Peripheral vowels are those located at the edge of the vowel envelope, and non-peripheral nuclei are those located on the inside. This assertion has not received as much scrutiny as it should. There are at least…
