In Shetland dialect, the northernmost branch of Lowland Scots, stressed monosyllables, when closed by a consonant, generally contain either a durationally short vowel followed by a durationally long consonant, or a long vowel followed by a short consonant. This feature, first described in the 1950s, can most likely be ascribed to the Scandinavian substratum of the dialect. Although several experimental investigations into the duration of Scottish vowels have been carried out recently, most of them in the light of the Scottish vowel length rule, none of them so far have looked at Shetland dialect or the relationship between the duration of the vowel and the final consonant. In the present study we will examine vowel and final consonant duration in monosyllabic words in both Shetland and Orkney dialects, as well as in Standard Scottish English and Standard Norwegian, in order to establish whether in Shetland dialect, durationally short consonants follow durationally long vowels and vice versa and if so, if this is indeed a feature peculiar to Shetland.

The appropriateness of using locus equations in a study of voiceless consonants is examined. The consonants investigated are the stops /t k/ and the fricatives /Θ s ∫/. The slope value of the locus equation, indicating degree of coarticulation in the CV syllable, is compared with electropalatographic (EPG) data on coarticulation. It is shown that, overall, there is a very poor correlation between locus equation and EPG data as regards coarticulation. It is also shown that more accurate locus equation results – in terms of their correlation with EPG data – are obtained for stop consonants when F₂ onset is sampled at stop release, rather than at the onset of voicing for the vowel. Finally, results for the voiceless consonants are compared with results for their homorganic voiced counterparts. Whilst there is no significant difference between voiced and voiceless consonants in the EPG data, there is a significant difference between voiced and voiceless consonants in the locus equation data. These results suggest that locus equations cannot provide invariant cues for stop and fricative place of articulation across the voiced-voiceless distinction.

A study of early X-ray footage of 4 subjects was conducted to test the prediction that there may be a midpharyngeal constriction in American English schwa. Results show a significant constriction during schwa relative to lingual rest position for all 4 speakers. This evidence contradicts views of American English schwa as having no articulatory target or place features, as well as those which have suggested a neutral target throughout the vocal tract. These findings, however, support claims connecting English schwa with reduced /r/. In addition to the basic effect 1 subject showed a bimodal pattern in schwa, which may indicate that this subject has distinct schwas in lexical vs. functional words, a property that has also been observed with respect to /r/ in r-vocalizing dialects.

The primary aim of this study was to determine if fluent early bilinguals who are highly experienced in their second language (L2) can produce L2 vowels in a way that is indistinguishable from native speakers’ vowels. The subjects were native speakers of Italian who began learning English when they immigrated to Canada as children or adults (‘early’ vs. ‘late’ bilinguals). The early bilinguals were subdivided into groups differing in amount of continued L1 use (early-low vs. early-high). In experiment 1, native English-speaking listeners rated 11 English vowels for goodness. As expected, the late bilinguals’ vowels received significantly lower ratings than the early bilinguals’ vowels did. Some of the early-high subjects’ vowels received lower ratings than vowels spoken by a group of native English (NE) speakers, whereas none of the early-low subjects’ vowels differed from the NE subjects’ vowels. Most of the observed differences between the NE and early-high groups were for vowels spoken in a nonword condition. The results of experiment 2 suggested that some of these errors were due to the influence of orthography.
