Abstract

This paper presents an acoustic description of laterals and nasals in an endangered minority language, Scottish Gaelic (known as 'Gaelic'). Gaelic sonorants are reported to take part in a typologically unusual three-way palatalisation contrast. Here, we consider the acoustic evidence for this contrast, comparing lateral and nasal consonants in both word-initial and word-final position. Previous acoustic work has considered lateral consonants, but nasals are much less well-described. We report an acoustic analysis of twelve Gaelic-dominant speakers resident in a traditionally Gaelic- speaking community. We quantify sonorant quality via measurements of F2-F1 and F3- F2 and observation of the whole spectrum. Additionally, we quantify the extensive devoicing in word-final laterals that has not been previously reported. Mixed-effects regression modelling suggests robust three-way acoustic differences in lateral consonants in all relevant vowel contexts. Nasal consonants, however, display lesser evidence of the three-way contrast in formant values and across the spectrum. We discuss potential reasons for lesser evidence of contrast in the nasal system, including the nature of nasal acoustics, evidence from historical changes, and comparison to other Goidelic dialects. In doing so, we contribute to accounts of the acoustics of the Celtic languages, and to typologies of contrastive palatalisation in the world's languages.
