Abstract:
Experimental and impressionistic observations show that
syllable-initial liquids in Southern British English are produced
with contrasting secondary articulations that seem to exhibit
far-spreading coarticulation on neighbouring syllables. This
study aimed to elucidate some of the factors that affect these
coarticulatory "resonance effects" due to /r/ vs. /l/. The focus
was the range and the structural conditions that affect the
spread of anticipatory resonance effects. The main variable of
interest was metrical structure, with a secondary focus on
segment type. Formant frequencies were measured in selected words
in 994 sentences spoken by one male. Anticipatory resonance
effects can affect as many as five syllables before the
conditioning /r/ or /l/ and can pass through up to two stressed
syllables. The data are interpreted in terms of two components, a
small, long-range effect, and a larger, more local one.
