Overview Gaelic: a sociophonetician’s perspective Stop consonants in Gaelic Acoustics of stops in Gaelic Research questions Methods Results Ongoing work Discussion
Gaelic: a sociophonetician’s perspective Bilingualism Language contact (Thomason 2007) Obsolescence and revitalisation (Dorian 1981, Jones 1998) Acoustic phonetic study of linguistic variation
Stop consonants in Gaelic Stops Word initial /p h t h k h / and /p t k/ Word medial and word final / h p h t h k/ and /p t k/ (Ladefoged et al. 1998) (Also palatalised vs. velarised distinction)
Initial stops bog ‘soft’ pòg ‘a kiss’ VOT Vowel voicing Closure Vowel voicing Closure
Pre-aspiration ‘Delay in the offset of normal voicing’ (Laver 1994:150) Vocal fold vibration and airflow independent
Pre-aspiration smoc ‘smoke’ snog ‘nice’ Vowel voicing Close Pre-asp Vowel voicing Closure
Pre-aspiration zoom in smoc ‘smoke’ Vowel voicing Close Pre-asp
Pre-aspiration zoom in smoc ‘smoke’ Close Pre-asp Breathy Voice Noise
Research Questions What are the phonetic correlates of the contrast /p h t h k h / and /p t k/ in modern Gaelic? Is this system changing?
Methods Native speakers of Lewis Gaelic 3 older generation, 3 younger Recording conditions Word list data 2257 tokens analysed Non-parametric statistical tests
Durational measures Segmenting on the waveform in Praat Modal voice Vowel Pre-aspiration BV Noise acaaca
VOT: Cho and Ladefoged (1999) Results – word initial
Results – word medial and final Pre-aspiration makes the contrast
Differences - initial
Differences – medial and final Calculated proportionally as well as raw numbers Breathy voice, closure, vot ns. Detail of pre-aspiration
Can you hear the difference? Older speaker: boc ‘male goat’Younger speaker: boc ‘male goat’ Younger speaker: smoc ‘smoke’Older speaker: smoc ‘smoke’
Summary Younger speakers: Longer VOT word initial position Shorter pre-aspiration word medial and final Pre-aspiration different: less voiceless
Ongoing work Adapted Zero Crossing Rate (Gordeeva and Scobbie 2010) In collaboration with Olga Gordeeva Quantifies pre- and post- aspiration Counts zero crossings in a band pass filtered sound file
Some preliminary results: Initial /k h /, /k/
Word medial / h k/, /k/
Conclusion Apparent time differences Comparison to Ladefoged et al. (1998): Real time change?
Conclusion Apparent time differences Comparison to Ladefoged et al. (1998): Real time change?
Conclusions Gradient phonetic shift (Babel 2009, Bybee 2010) Obsolescence / contact / ‘normal’ change? Lexical attrition
