Linguis'c and extra-‐linguis'c constraints on preaspira'on in
Bethesda Welsh
Jonathan Morris (Cardiff University) Michaela Hejná (Newcastle University)
Outline • Study of pre-‐aspira'on before for's plosives in Bethesda (North West Wales):
Ø Frequency of occurrence
Ø Dura'on
Ø Noisiness
• Correla'ons with speaker sex and home language.
• Ini'al findings of pre-‐aspira'on before lenis plosives.
Research Context • Sugges'ons that pre-‐aspira'on could be a non-‐obligatory feature of many varie'es of Welsh and Welsh English (Ball 1984: 18; Morris 2010; Hejná 2015; Hejná in prep a).
• Evidence that women pre-‐aspirate more frequently (e.g. Docherty & Foulkes 1999; Helgason 2002).
• Effects of language contact and synchronic bilingualism on Welsh-‐English bilingual phone'cs (Morris 2013; Mayr et al. 2015; Mennen et al. 2015).
Data • 16 speakers aged between 16 and 18 (dataset equally stra'fied in terms of sex and home language).
• Wordlist data collected as part of a previous project (Morris 2013).
• For's (n=698) and lenis tokens (n=266). Examples include: ‘siop’ shop, ‘brat’ apron, ‘clec’ smack ’bod’ be, ‘baban’ baby, ’cig’ meat.
Measurements
Coding and analysis • Frequency: Presence of breathiness, pre-‐aspira'on,
or both.
• Dura'on: % of the token.
• Noisiness: Band-‐pass filtered zero crossing rate using an automated script developed by Gordeeva & Scobbie (2010).
• Mixed Effects Models (R Core Team 2015) using lme4 and lmerTest packages (Bates et al. 2015; Kuznetsova 2015).
Frequency • 87.2% of for's tokens pre-‐aspirated (n=609). • More likely to occur before /t/ and /k/ than /p/ (p < 0.01).
Frequency
• High vowels less frequently pre-‐aspirated (but not significant).
Frequency
• Not found to be significant.
Dura'on
• Gender/Sex (p < 0.01)
Dura'on
• Home language (p < 0.01)
Noisiness • Sensi've to place of ar'cula'on (p < 0.05)
Noisiness • Sensi've to vocalic condi'oning. • <a> vs <i>, <io>, <u>, <w> (p < 0.01).
Noisiness • Gender/Sex (p < 0.01)
Lenis plosives • /b, d, g/: omen voiceless and pre-‐aspirated. • Pre-‐aspira'on found before 47.7% of lenis stops (n=127):
Lenis plosives • /b, d, g/: omen voiceless and pre-‐aspirated. • Pre-‐aspira'on found before 47.7% of lenis stops (n=127):
Phone'c discussion • Pre-‐aspira'on least frequent and least noisy
– with /p/ (as opposed to /t/ and /k/) – with high vowels
• This is found across languages (for frequency and dura'on; noisiness not analysed).
PLACE:
– English (Hejná 2015: 99-‐104; Morris 2010: 10) – Icelandic (Ní Chasaide 1985: 126) – Italian (Stevens & Hajek 2004a: 58, 2004b: 342; Stevens 2010: 101) – North Wales Welsh (Morris 2010: 10) – Scopsh Gaelic (Nance & Stuart-‐Smith 2013: 10; Ní Chasaide 1985: 126) – Swedish (Helgason & Ringen 2008: 623)
HEIGHT: – English (Gordeeva & Scobbie 2007: 1; Hejná 2015: 104-‐8) – Italian (Stevens & Hajek 2004a: 59) – Skolt Sámi (McRobbie-‐Utasi 1991: 10, 2003: 3) – Western Yugur (Roos 1998: 32)
• Why?
Discussion: place condi'oning • VOT explana'ons (Cho & Ladefoged 1999)
pressure built-‐up behind the closure (NA) mass of air before the constric'on point (NA) velocity of the ar'culator (yes) ar'culator mass in contact (yes) glotal opening area (NA) temporal adjustment between closure and release dura'on (can be, but not ar'culatory)
• Could pre-‐aspira'on paterns be beter explained by an'cipatory and
perceptual mo'va'ons? • For example: If a plosive is foot-‐final and followed by a pause, the cues to
place may not be salient enough • à pre-‐aspira'on mirrors post-‐aspira'on to preserve place contrast • needs to be tested, but problema'c because of phonologisa'on
Discussion: vocalic effects • opposite paterns found for vowel devoicing • mo'va'ons cannot be the same as those proposed for vowel
devoicing (Ohala 2011)
• opposite paterns found for post-‐aspira'on: longest with high vowels (e.g. Chang et al. 1999; Nearey & Rochet 1994), although not always
• mo'va'ons cannot be the same
• There could be two types of vowel devoicing: – “vowel devoicing”: mechanic & in unstressed syllables – “pre-‐aspira'on”: a. place contrast preserving & an'cipa'on of
post-‐aspira'on b. syllable-‐'ming preserving & primarily in stressed syllables (pre-‐aspira'on)
Further work • Does pre-‐aspira'on in lenis plosives patern like pre-‐
aspira'on in for's plosives?
• To what extent is pre-‐aspira'on a feature in areas where the use of Welsh by the community is less, and where other varie'es of English may have had more influence historically?
• How salient is pre-‐aspira'on to listeners?
• Rela'onship between pre-‐aspira'on & breathiness?
– breathiness as a precursor to pre-‐aspira'on (Hejná in prep b)
• Is it physiological sex or gender that biases pre-‐aspira'on?

Pre-‐aspira'on • A period of breathy voice and voiceless pre-‐aspira'on as a result of the abduc'on of the glops prior to the stop closure (Helgason 2002: 9; Nance & Stuart-‐Smith 2013: 130).
• Either as an obligatory feature or one which can be present or absent and subject to sociolinguis'c constraints (see Nance & Stuart-‐Smith 2013 for refs).
Frequency • No effect
Dura'on • No effect of place of ar'cula'on
Dura'on • No effect of the vocalic factors
Noisiness • No effect of home language
