The Way

ABSTRACTSamples of speech suitable for sociolinguistic analysis may be sought in several ways. Interviews (either formal or informal), and tape-recorded group sessions, are the methods most used currently. In research on a specific variable, the historical present tense (HP), none of these methods proved neutral or adequate. Although the historical present tense is very widely used in conversational narratives, its occurrence within interviews is so infrequent as to be striking. An explanation was found in the way in which the interview has a specific known place as a speech event in the culture of those whose speech was being studied. The so-called spontaneous interview does not have such a place, and for that very reason is even less satisfactory a source of data. The notion of natural speech is taken as properly equivalent to that of appropriate speech; as not equivalent to unselfconscious speech; and as observable easily, and often best, by simple techniques of participation.

Constituent Order

Primary auditory stream segregation, the perceptual segregation of acoustically related elements within a continuous auditory sequence into distinct spatial streams, prevents subjects from resolving the relative constituent order of repeated sequences of tones (Bregman & Campbell, 1971) or repeated sequences of consonant and vowel sounds (Lackner & Goldstein, 1974). To determine why primary auditory stream segregation does not interfere with the resolution of natural speech, 8 subjects were required to indicate the degree of stream segregation undergone by 24 repeated sequences of English monosyllables which varied in terms of the degrees of syntactic and intonational structure present. All sequences underwent primary auditory stream segregation to some extent but the amount of apparent spatial separation was less when syntactic and intonational structure was present.

Consonant Voicing

This paper reports two experiments, each designed to clarify different aspects of bilabial stop consonant production. The first one examined events during the labial closure using kinematic recordings in combination with records of oral air pressure and force of labial contact. The results of this experiment suggested that the lips were moving at a high velocity when the oral closure occurred. They also indicated mechanical interactions between the lips during the closure, including tissue compression and the lower lip moving the upper lip upward. The second experiment studied patterns of upper and lower lip interactions, movement variability within and across speakers, and the effects on lip and jaw kinematics of stop consonant voicing and vowel context. Again, the results showed that the lips were moving at a high velocity at the onset of the oral closure. No consistent influences of stop consonant voicing were observed on lip and jaw kinematics in five subjects, nor on a derived measure of lip aperture. The overall results are compatible with the hypothesis that one target for the lips in bilabial stop production is a region of negative lip aperture. A negative lip aperture implies that to reach their virtual target, the lips would have to move beyond each other. Such a control strategy would ensure that the lips will form an air tight seal irrespective of any contextual variability in the onset positions of their closing movements.

Twenty children who have worn a Cochlear Corporation cochlear implant for an average of 33.6 months participated in a device-on/off experiment. They spoke 14 monosyllabic words three times each after having not worn their cochlear implant speech processors for several hours. They then spoke the same speech sample again with their cochlear implants turned on. The utterances were phonetically transcribed by speech-language pathologists. On average, no difference between speaking conditions on indices of vowel height, vowel place, initial consonant place, initial consonant voicing, or final consonant voicing was found. Comparisons based on a narrow transcription of the speech samples revealed no difference between the two speaking conditions. Children who were more intelligible were no more likely to show a degradation in their speech production in the device-off condition than children who were less intelligible. In the device-on condition, children sometimes nasalized their vowels and inappropriately aspirated their consonants. Their tendency to nasalize vowels and aspirate initial consonants might reflect an attempt to increase proprioceptive feedback, which would provide them with a greater awareness of their speaking behavior.

PurposeNatural speech comes with variation in pitch, which serves as an important cue for speech recognition. The present study investigated older listeners' dynamic pitch perception with a focus on interindividual variability. In particular, we asked whether some of the older listeners' inability to perceive dynamic pitch stems from the higher susceptibility to the interference from formant changes.MethodA total of 22 older listeners and 21 younger controls with at least near-typical hearing were tested on dynamic pitch identification and discrimination tasks using synthetic monophthong and diphthong vowels.ResultsThe older listeners' ability to detect changes in pitch varied substantially, even when musical and linguistic experiences were controlled. The influence of formant patterns on dynamic pitch perception was evident in both groups of listeners. Overall, strong pitch contours (i.e., more dynamic) were perceived better than weak pitch contours (i.e., more monotonic), particularly with rising pitch patterns.ConclusionsThe findings are in accordance with the literature demonstrating some older individuals' difficulty perceiving dynamic pitch cues in speech. Moreover, they suggest that this problem may be prominent when the dynamic pitch is carried by natural speech and when the pitch contour is not strong.
