ABSTRACT
This study investigates the production and auditory lexical processing of words involved in a patterned phonological alternation in two dialects of Catalan spoken on the island of Majorca, Spain. One of these dialects, that of Palma, merges /É/ and /o/ as [o] in unstressed position, and it maintains /u/ as an independent category, [u]. In the dialect of Sóller, a small village, speakers merge unstressed /É/, /o/, and /u/ to [u]. First, a production study asks whether the discrete, rule-based descriptions of the vowel alternations provided in the dialectological literature are able to account adequately for these processes: are mergers complete? Results show that mergers are complete with regards to the main acoustic cue to these vowel contrasts, that is, F1. However, minor differences are maintained for F2 and vowel duration. Second, a lexical decision task using cross-modal priming investigates the strength with which words produced in the phonetic form of the neighboring (versus one's own) dialect activate the listeners' lexical representations during spoken word recognition: are words within and across dialects accessed efficiently? The study finds that listeners from one of these dialects, Sóller, process their own and the neighboring forms equally efficiently, while listeners from the other one, Palma, process their own forms more efficiently than those of the neighboring dialect. This study has implications for our understanding of the role of lifelong linguistic experience on speech performance.

The Spanish voiced obstruents /b d g/ are traditionally described as having each two allophones: stop and fricative (approximant) in complementary distribution. Several researchers have noted that some Central American and Highland Colombian varieties deviate from the general allophonic distribution in showing a preference for stop realizations in all contexts, except for the intervocalic position. In this paper we report on a large-scale acoustic investigation of /b d g/ in postconsonantal (after a liquid, sibilant or glide) and postvocalic (after /a/) contexts in Costa Rica Spanish, establishing a comparison with the variety of Madrid, Spain, which we take as representative of a variety with the general pattern of allophony. Our study, based on a continuous measurement of intensity, confirms previous descriptions in that Costa Rica Spanish does indeed show a different pattern of allophony from that found in the Madrid variety. The analysis shows that in Costa Rica Spanish postconsonantal realizations of /b/ and /d/ are very different from postvocalic ones, with a clear separation in the degree of constriction between these two contexts. In Madrid, on the other hand, we find a continuum of constriction degrees, depending on the nature of the specific preceding segment, and without a clear separation between postvocalic and postconsonantal realizations. The question that naturally arises is that of the historical connection between these two patterns of allophony, for which we offer some speculation, based in historical parallels and comparison with other varieties.

The present study investigates the acoustics (F1 × F2) of Catalan and Spanish mid-back vowels as produced by highly proficient, early Spanish-Catalan bilinguals residing on the island of Majorca, a bilingual speech community. Majorcan Catalan has two phonemic mid-back vowels in stressed positions (/o/ and /c/) while Spanish possesses only one (/o/). Two groups of bilinguals were recruited and asked to produce materials in both languages - one group of Spanish dominant and one of Catalan-dominant speakers. It was first found that Catalan and Spanish /o/ are virtually indistinguishable. Catalan /c/ is lower and more fronted than the other two vowels. Spanish-dominant bilinguals were found to differ from Catalan-dominant ones in that they did not produce the Catalan-specific /o/-/c/ contrast in their speech; that is, they produced a single, merged Catalan mid-back vowel. A within-subjects analysis of first- and second-language mid-back vowels further suggested, for Spanish-dominant bilinguals, that they had developed a separate vowel category to accommodate their single, merged Catalan mid-back vowel; that is, they possessed a two-category mid-back vowel system, i.e. one for their Spanish /o/ and one for their merged Catalan /o/ + /c/. Potential explanations and theoretical implications are discussed.
