Abstract:
|
|
This dissertation investigates whether there are systematic individual
differences in the perceptual weighting of frequency and duration speech
cues for vowels and fricatives (and their non-speech analogues) among a
dialectally homogeneous group of speakers. Many of the previous studies on
individual differences have failed to control for the dialects of the
subjects, which suggests that any individual differences that were found
may be dialectal. Dialect production and perception tasks were included in
this study to help ensure that subjects are not from dissimilar dialects.
The main task for listeners was AX discrimination for four separate types
of stimuli: sine wave vowels, narrowband fricatives, synthetic vowels, and
synthetic fricatives. Vowel stimuli were based on the manipulation of
duration and frequency of F1 for the vowels in 'heed' and 'hid', while
fricative stimuli were based on the manipulation of the fifth frequency
centroid of the fricatives in 'bath' and 'bass'. Multidimensional scaling
results indicate that there are subgroups within a dialect that attend to
frequency and duration differently, and that not all listeners use these
cues consistently across dissimilar phones. Results of this study will be
relevant to the fields of perception, feature phonology, dialectology, and
language change. If subgroups can have different perceptions of speech
(but similar productions), this questions what is needed to classify
dialect continua, and the ratios of these subgroups changing over time can
explain some language mergers and shifts.
