Perception and production of English vowels by German learners: instrumental-phonetic support in language teaching.

Results are presented from two experiments which examine the application of instrumental phonetic methods to the needs of the teacher of a foreign language. First, the use of a traditional psychophonetic test procedure as a diagnostic tool is demonstrated. Second, the effect of reading, imitation, and prompted recall on production is examined, and the implications for teaching and pronunciation monitoring discussed.

Some problems of interarticulator phasing as an index of temporal regularity in speech.

Tuller, Kelso, and Harris (1982) offered evidence that the relative timing of articulators in speech remains constant over changes in stress and speech rate. Their evidence is discussed in the light of the methods used, and alternative approaches are suggested. Further, the statements are compared with those of an earlier study within the same theoretical frame, and the implications for a model of speech production are briefly discussed.

Click placement and units of perceptual processing.

The relationship between experimental method and the perception hypothesis being examined is a particularly critical one. Here, earlier studies employing the click-placement method are surveyed, and the conclusions drawn there about the perceptual processes involved are discussed. A working hypothesis is developed which enables an examination, for the first time, of Ladefoged and Broadbent's [1960] original claim concerning basic processing units. Within a hypothetical framework of hierarchically organized perceptual decisions, the click-placement task is applied in a series of experiments designed to approach the question of processing units at segment, syllable and foot level. Evidence is found for the psychological reality of the syllable and foot. The phonetic basis of the foot is examined and found to be replaceable by top-down information. Between foot and syllable level, indications of differential word demarcation were found, dependent on differences in segmental structure.

Complex encoding in word-final voiced and voiceless stops.

The multifunctionality of vowel and closure duration is investigated in two experiments using the word pair 'bag'-'back'. In experiment I, categorization of synthetic stimuli at three simulated rates of speech supports the notion of the vowel/vowel + closure quotient as a tempo-independent cue to the final 'voiced'-'voiceless' opposition. In experiment II, manipulated natural stimuli are tested at two rates of speech, sentence-medially and finally. In final position, the results of experiment I are confirmed though durational and nondurational properties interact. Medially, a specific context effect is found.
