Some Consequences of Velarization on Catalan Vowels.
Widdison, Kirk
The acoustic effects of the syllable-final /l/ significantly alter the vocalic timbre of the preceding vowel in Catalan. Vowel quality is modified anticipatory to the articulatory gestures required by the /l/, resulting in a lowered second formant. Syllable-final /l/ in Catalan is heavily velarized as a result of tongue tip-tongue back coupling and presents many of the characteristics of an offglide (/w/) movement. This velarized segment is less segmentable from the vowel portion it follows, which may cause a change in the listener's perception of vowel duration. These co-articulatory effects are greatest in the case of front vowels and are of particular interest with respect to the mid-front phonemes. Historical phonology states that phonetic shifts in these vowels were generally exempted in the conditioning environment of liquid sounds. It is argued that the above-mentioned effects underlie this resistance. Evidence to support these claims is sought in the form of acoustic analysis of vowel-lateral and lateral-vowel sequences. The results favor the accepted phonological theory. (Author)
