Research

Interest: Mono Lake Northen Paiute (MLNP)Three-way contrast in medial obstruents

(fortis, voiced fortis, lenis)

Problem: Existence of the three-way contrast has been long recognized; however, phonetic properties of each sound are not well understood.

Goal: Identify acoustic properties that make fortis, voiced fortis, and lenis as distinctive type of sound.

aaga [aaɣa] taka [takka] kɨggɨ [kɨggɨ] ’crow’ ‘arrowhead’ ‘leg’

Auditory impressions

Liljeblad (1950, 1966), Nichols (1974), Thornes (2003) Often mentioned parameters

Duration: fortis > lenis Voicing: fortis - voiceless; lenis - voiced Manner: lenis - continuant; fortis - stop

Canonical fortis = long voiceless stop Canonical lenis = short voiced continuant

*But great deal of free variation

Characteristics accompanying fortis Preaspiration & Preglottalization Abrupt vowel-stop transition

Instrumental Studies

Waterman 1911 (physiological data)Fortis has twice longer closure duration than

lenisNP lenis does not have pre-voicingVowels have final aspiration before fortis

Summary

Consonantal duration:

fortis, voiced fortis > lenis Consonantal period = [h/Ɂ] + [C] Lenis: smooth VC transition Fortis: Preaspiration Voiced fortis: Preglottalization(?) VOT: fortis > voiced fortis

Implication 1: on the typology of fortis/lenis contrast

Ladefoged & Maddieson (1997)

Fortis: increased respiratory or articulatory effort in the production of the segment (Lenis: opposite)

Articulatory effort in MLNP fortis: use of laryngeal involvement at VC juncture

Locus of force exertion

Korean: CV, no word-final F/L contrast MLNP: VC, no word-initial F/L contrast

Implication 2: on the typology of stop

Rarity of long voiced stop due to Aerodynamic Voicing Constraints Ohala (1983)

Extra articulatory effort is required to maintain vocal fold vibration throughout the oral closure.

Phonological long voiced stop → phonetic voiceless unaspirated stop (e.g. MLNP voiced fortis)

Subtle difference in VOT between fortis and voiced fortis

Merger to fortis in other NP dialects

Implication 3: source of voiced fortis in MLNP

Possible scenarioVɁC > voiced fortis

Supporting evidenceFortis sonorant freely varies with [Ɂ C]

e.g. kwinna ~ kwiɁna ‘eagle’

mommogoni ~ moɁmogoni ‘women’
