Four Dutch-English bilinguals were asked to imitate and to identify 64 isolated vowel stimuli. Imitation behavior turned out to be categorical to some degree, comprising vowel phonemes from both languages. A significant correlation was found between identification categories and imitation clusters. (Author/CFM)

This paper examines the distinction between primary and secondary articulations of consonants. It shows that the description and classification of speech sounds should not be based on physical parameters alone. Some essential distinctions reveal themselves only inferentially through the relation of a sound to others in the language system.…

Sentences were read by six informants to determine the presence or absence of /n/ in /nth/ sequences. The sentences contained seven different levels of juncture with /nth/ occurring in word final position, intervocalically, and across word boundaries, among other places. Dental coarticulation was not hindered by most junctures. (SC)

Investigates the principles underlying the perception of vowel stimuli. The results support Chistovich's claim. When judging the distance between synthetic vowel stimuli, speakers refer to the phonemic structure of their native language. They determine the phonemes closest to the stimuli and then compare the phonemes and not the stimuli…

Establishes the relationship between linguistic stress and fundamental frequency and the intonation contours in short declarative sentences, interrogative sentences, and nonterminal clauses in Advanced Standard Copenhagen Danish. The work is based on acoustical analyses of recordings by four subjects. (Author/EJS)

An experiment tests conjectures that right ear advantage (REA) has an auditory origin in competition or interference between acoustically similar stimuli and that feature-sharing effect (FSE) has its origin in assignment of features of phonetically similar stimuli. No effect on the REA for acoustic similarity, and a clear effect of acoustic…

Argues that generative phonology is not predictive of phonological identification, thus preventing it from achieving descriptive adequacy and limiting its value in explaining human speech perception. The assumption that the unity of the morpheme must be expressed phonologically is rejected. (Author/EJS)

Tested whether listeners' reaction times for monitoring a predetermined phoneme are influenced by phonetic constraints on ordering. Reaction times were significantly shorter for phoneme monitoring in monosyllable-bisyllable sequences than in bisyllable-monosyllable sequences; however, reaction times were not significantly different for high-low vs…

Underwater intelligibility of three standard word lists is evaluated in two experiments. Results indicate that words which are equated for difficulty in normal conditions are likewise equated under water. Phoneme distortion was examined in a multiple choice test which showed fricatives and place of production to be most affected under water. (SC)

A model of phoneme identification is proposed which describes the process by which continuous acoustic featural information about the place of articulation and the voicing of speech sounds is integrated during phoneme identification. (AM)

Stampe's (1969, 1973) hypotheses regarding innate mental phonological processes are tested against some of the extant data on speech perception. (AM)
