In this study the dynamics of lip rounding are investigated. Lower lip protrusion was measured in a frame-by-frame analysis of six high-speed (66 frames/sec) cinephotographic films: three for English (with one speaker) and three for French (with three different speakers). A corpus of utterances was constructed for each film separately using results and hypotheses derived from previous film(s). With the techniques applied in this study, no reliable method of determining onset of rounding could be established for English and thus the effect of syllable and word boundary position on coarticulation patterns could not be determined. Consonant context appeared to have a greater effect on timing of extremum protrusion with respect to acoustic onset of the vowel, than did degree of stress. For French, there was evidence to suggest that coarticulation of rounding may be phonemic. Although the data were limited, it was observed (for one pair of "minimal" sequences said by one subject) that the onset of rounding occurred later than reported by Daniloff and Moll (1968) for English or by Kozhevnikov and Chistovich (1965) for Russian. As in the case of the English data, no obvious difference in timing of extremum protrusion was found for variations in stress for the French data. It was concluded that for both English and French some of the basic assumptions of the experiment were untenable. In particular, it is questionable that a point of onset of rounding before, during, or after a consonant cluster can be specified without first systematically determining the amount of protrusion which is associated with each consonant in isolation and then in various contexts. It is apparent from the data that coarticulation of rounding is likely to be influenced by other parameters such as intonation, stress and phonetic (in particular consonantal) context. Future research should attempt to control as many of these parameters as possible before significant patterns (if they exist) can be observed. / Medicine, Faculty of / Audiology and Speech Sciences, School of / Graduate

The present study is an attempt to gain insight into the perceptual mechanism for consonant clusters and to discern its relationship to existing theories of speech perception. Nonsense syllables were constructed, consisting of the vowel /I/ and 18 two consonant clusters composed of one of the fricatives /s/, /f/, and /∫/ and one of the plosives /p/, /t/, and /k/ in either order. Some of these clusters form permissible English clusters, the others impermissible clusters. These clusters appeared in three positions; initial, medial (followed by /in/ ), and final. They were recorded by a trained phonetician. Pink noise at a +3 dB signal-to-noise ratio (determined from peak readings) was used to mask the signal. Nine experimental tapes (three for each cluster position) were constructed; 108 items were presented on each tape. Eighteen subjects (nine males and nine females) each listened to one tape for each position and responded according to a forced choice paradigm to each item by writing the cluster they perceived. Responses for all subjects and for each position were tabulated in confusion matrices and analyzed according 1) to permissibility as English clusters, 2) to manner of articulation, 3) to place of articulation and 4) to differentiation according to the distinctive features of [anterior], [coronal], and [distributed]. Inspection of these confusion matrices indicated that there may be some difference in the perception of permissible and impermissible clusters; however, results are not conclusive. The proposal that clusters are perceived as a unit is refuted by the results obtained. Manner of articulation was identified correctly more frequently than place of articulation. Place of articulation for fricatives was identified correctly more frequently than place of articulation for plosives. Analyses according to distinctive features provides some support for distinctive features. The relationship of the results of this study to four major theories of speech perception is discussed. Three of these can be used to explain some aspect of the responses observed. / Medicine, Faculty of / Audiology and Speech Sciences, School of / Graduate

This dissertation is a report on the articulatory and acoustic investigation of Seneca speech as compiled by a native speaker of the Seneca language. The body of the dissertation consists of four chapters. In Chapter 1, earlier analyses of the sound patterns of Seneca are introduced and discussed. Several problematic aspects of Seneca are highlighted and these are discussed in later chapters. Chapter 2 is a subjective analysis of Seneca articulation. The author has discovered that the Seneca language is articulated from a different articulatory base (referred to as the "Seneca neutral position"), than is found in other languages. Of special interest are the vowel combinations as well as the sequences of consonants in syllable initial position such as /kn/ and /kd/ which are produced with a unique order of articulatory gestures. Chapter 3 displays the results of an acoustic study of Seneca speech. The primary instruments employed in this study were a sound spectrograph and a pair of pneumotachometers which were coupled to a specially modified surgical mask so that the air flow in the nasal and oral cavities could be measured independently. Many of the proposals made in the subjective analysis are substantiated by the results of the instrumental analysis. Chapter 4 presents a discussion of the theoretical consequences of this study. In particular, the facts of Seneca articulation suggest the inapplicability of the Chomsky & Halle distinctive features as presented in the book The Sound Pattern of English (1968). The author proposes supplementing the tongue body features high, low, and back with two additional features which specify a degree of mouth opening due to the tongue blade/mandible position. These additional features, [± open], [± close] are necessary to account for the articulation of Seneca.
