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.

By electronically segmenting stimuli in German, two tests of perception of quantity related to tense or lax syllabic quantity were made possible. In one, the physical duration of the stressed vowel was shortened, and in the other, the occlusion of the consonant following the stressed vowel was shortened. (MSE)

A detailed analysis of the oral vowels in the French phoentic system and their nasal equivalents. (Text is in French.) (PMP)

Research carried out with the support of the Fonds de la Recherche Fondamentale Collective (Foundation for Joint Basic Research). (VM)

Vowel quality in pretonic syllables seems to result both from the interaction of the four main parameters of stress within the syllable and from the relationship of these values to those of the tonic vowel. (Author/MSE)

This test, conducted to prove that closed vowels can be heard in fricative utterances as open vowels in explosive utterances, gives further evidence for the closing action of constrictives and the opening action of occlusives. It also reveals a possible articulatory and auditive convergence between consonants and vowels. (Text is in French.)…

Discusses the disappearance of the opposition between two phonemes in modern spoken French, and cites examples from popular songs and sketches. (Text is in French.) (AM)

A study of the opposition in terms of duration between long and short vowels in the German phonological system. Tables, graphs and analyses accompany the conclusions discussed. Since physical time is not the only distinctive feature, loss of the temporal cue is compensated for by spectral cues. (Text is in French.) (AMH)

This article describes an experiment in which the following hypothesis was tested and supported: that tension serves to reinforce the phoneme's articulatory characteristic, whether it be closure or openness; and that audibility interferes with perception of tension. (Text is in French.) (AM)

This article presents a sensory description of the sounds of language which differs from the traditional acoustic or articulatory description. The main idea is that sounds differ according to auditory and extra-auditory factors. (Text is in French.) (AM)

A report on a diagnostic study of the Sicilian way of pronouncing the French /y/. On the basis of this study, a quantitative analysis of verbo-tonal methods of correction is made. Some such methods are based on intonation, rhythm, syllabication and combinatory phonetics. (Text is in French.) (AMH)

Dyslalia refers to a broad spectrum of language pronunciation difficulties; the subjects of this experiment experienced only minor distortions in articulation. (DD)
