Abstract:
The research presented in this thesis uses various instrumental techniques to determine the main phonetic characteristics of the Intervocalic stops in both British English and Korean. Pilot experiments were carried out using structured /VCV/ nonsense isolated items (chapter 2 and 3), and the results of the pilot experiments were confirmed with real speech items in connected speech In the main experiment (chapter 4). The results show that in intervocalic positions, the lax (phonologically voiced in BrEng and unaspirated lax in Korean) and tense (voiceless in BrEng and aspirated tense in Korean) stops are significantly differentiated by the duration of the preceding vowel, the duration of oral closure and maximum lingual contact and that the Korean phonologically unaspirated tense and lax stops are significantly differentiated by these measures also. The results also show that in intervocalic position, the so-called lax stops (phonologically voiced in BrEng and unaspirated lax in Korean) are rarely voiced throughout the closure phase but have a substantial period of devoicing and a measurable VOT. Also full voicing does not automatically occur as the duration of oral closure of a stop is reduced. The underlying physiological mechanism for voicing and devoicing during intervocalic stops in the two languages was discussed in the light of data on glottal area from a photo-electric glottograph. Some physiological explanations for the effect on the phonetic variables of the place of articulation, stress placement and tempo variation are discussed.
