Zusammenfassung der Projektergebnisse

The project has been concerned with an investigation of the mechanisms of sound change and their relationship to the production and perception of speech, with specific reference to the standard accent of England Southern British English (SBE). A particular focus of the project has been on assessing the extent of sound change through apparent time studies comparing younger and older speakers by which /u, ʊ/ (lexical sets GOOSE, FOOT) have fronted in the last 50 years. A new approach in this study has been to investigate both the production and the perception of /u, ʊ/ within the same speaker and across two generations. The results of these studies show that /u, ʊ/ are fronted phonetically in younger speakers compared with older speakers. For /u/, younger speakers also showed a parity between production and perception: compared with older speakers, younger speakers had a fronted /u/ in both modalities and the effects of context on either production or perception was less than for older speakers. Similar results were also obtained for the more recent phonetic fronting of /ʊ/ except that perception and production were misaligned in younger speakers: that is, the influence of context in perception was less than in their production which suggests that the sound change may affect perception before production. Subsequent studies were concerned with the physiological mechanisms of /u, ʊ/ fronting. The results showed that the /u, ʊ/ fronting is brought about by tongue-dorsum fronting and not liprounding: physiological studies suggest that the pairs /i, u/ (FLEECE, GOOSE) and /ɪ, ʊ/ (KIT, FOOT) are distinguished in SBE principally by the absence and presence of lip rounding respectively, given that they differ minimally in tongue position. These results also show that SBE /u, ʊ/ can no longer be regarded as back or even central vowels. A further physiological study of all German tense and lax vowels in three consonantal contexts showed that /u/ may be more prone to fronting in the world's languages than /i/ to retraction. This is because the mean tongue dorsum position for /u/ is much for distant from the centre of the speaker's vowel space than is /i/, and because /u/ is produced with particularly high peak velocity. A further reason why /u/ may be more likely to front than /i/ to retract is because there is a slightly greater bias in the languages of the world for /u/ to follow consonants that induce phonetic fronting than for /i/ to follow consonants that induce phonetic retraction. A third part of the project was concerned with the relationship between vowel changes due to physiological ageing and phonetic sound change. The study was longitudinal involving the analysis of over 60 years of broadcast material from two speakers. The results showed that with increasing age, the first formant frequency tracks the falling fundamental frequency especially in phonetically low vowels and to a lesser extent in phonetically high vowels. The importance of this finding is firstly that studies investigating the diachronic change to phonetic height based on apparent time studies need to factor out the confounding F1 changes in open vowels due to increasing biological age; and secondly, that F1 may track f0 in order for the perceived quality of phonetic height to remain approximately constant with increasing age.
