In the Southern Bavarian variety of Tyrolean, laryngeal contrasts undergo a typologically interesting process of neutralisation in word-initial position. We undertake an acoustic analysis of Tyrolean stops in word-initial, word-medial intersonorant and word-final contexts, as well as in obstruent clusters, investigating the role of the acoustic parameters VOT, prevoicing, closure duration and F0 and H1–H2* on following vowels in implementing contrast, if any. Results show that stops contrast word-medially via [voice] (supported by the acoustic cues of closure duration and F0), and are neutralised completely in word-final position and in obstruent clusters. Word-initially, neutralisation is subject to inter- and intraspeaker variability, and is sensitive to place of articulation. Aspiration plays no role in implementing laryngeal contrasts in Tyrolean.

Sound Changes

The Discussion chapter summarizes the main findings of the book regarding those contextual, positional, and prosodic conditions which trigger velar and labial softening, and the acoustic cues which are responsible for the integration of (alveolo)palatal stops as affricates differing in place of articulation. The arguments in support of an articulation-based interpretation of these sound changes are also summarized and evaluated. The chapter also addresses some phonological issues, namely, why (alveolo)palatal stops are phonetically but not phonologically frequent, and the extent to which their realization is conditioned by the number of dorsal-stop phonemes in the language.

Stress Patterns

Two talkers with normal hearing and speech presented with voice 240 common nouns (80 monosyllables, 80 trochees, 80 spondees) to six profoundly deaf children whose task was to lipread without acoustic cues at distances from 5-100 ft. Under bright, shadow-free illumination, lipreading performance diminished from 75% correct at 5 ft to 11% correct at 100 ft. Scores varied with distance similarly for both talkers. The stress patterns of the stimulus words influenced their intelligibility, with scores decreasing from spondees to trochees to monosyllables. In a supplementary study, one talker presented two tests of phoneme recognition to the same six deaf children whose task was to lipread from 5, 20, or 70 ft. Identification of consonants in VCV context depended on their place of articulation (front superior to back) and on the surrounding vowel (/a–a/ superior to /i–i/ or /u–u/). Vowel-identification scores were less dependent on distance than were consonant-identification scores. In general, tense (stressed) vowels were more easily identified in /b/-V-/b/ context than were lax (unstressed) vowels.

The McGurk effect demonstrates that the perceived place of articulation of an auditory consonant (such as /bi/) can be influenced by the simultaneous presentation of a videotape of a talker saying a conflicting consonant such as /gi/. Usually, such a presentation is perceived by observers as “di” or “ð” (known as fusion responses). The reverse pairing (auditory /gi/ paired with a visual /bi/) results in “bgi” percepts. These are known as combination responses. In the current study, three experiments examined how acoustic information about place of articulation contained within the release bursts, aspiration, and voiced formants and transitions of a consonant contribute to the McGurk effect. In the first experiment, the release bursts and aspiration were deleted from the acoustic signal. This manipulation resulted in a smaller impact on McGurk “fusion” tokens relative to the McGurk “combination” tokens. This asymmetry may be related to the perceptual salience of the release bursts and aspiration for velar compared to the bilabial tokens used in this experiment and their importance for obtaining the combination percept. In Experiment 2, the release bursts and aspiration were increased in amplitude. Results revealed either no effect or a stronger McGurk effect for the manipulated tokens than for the intact tokens. This finding suggests that the McGurk effect for fusion tokens does not occur simply because the release bursts and aspiration are weak. In Experiment 3, low-pass filtering the second and higher formants and transitions was associated with the largest overall impact on the McGurk effect. This suggests that dynamic information contained within these formants is of primary importance in obtaining the McGurk effect. These cues are, however, context-dependent and vary as a function of talker and vowel context.

Purpose In this study, the authors aimed to investigate how listener training and the presence of intermediate acoustic cues influence transcription variability for conflicting cue speech stimuli. Method Twenty listeners with training in transcribing disordered speech, and 26 untrained listeners, were asked to make forced-choice labeling decisions for synthetic vowel–consonant–vowel (VCV) sequences “a doe” (/ədo/) and “a go” (/əgo/). Both the VC and CV transitions in these stimuli ranged through intermediate positions, from appropriate for /d/ to appropriate for /g/. Results Both trained and untrained listeners gave more weight to the CV transitions than to the VC transitions. However, listener behavior was not uniform: The results showed a high level of inter- and intratranscriber inconsistency, with untrained listeners showing a nonsignificant tendency to be more influenced than trained listeners by CV transitions. Conclusions Listeners do not assign consistent categorical labels to the type of intermediate, conflicting transitional cues that were present in the stimuli used in the current study and that are also present in disordered articulations. Although listener inconsistency in assigning labels to intermediate productions is not increased as a result of phonetic training, neither is it reduced by such training.
