Nasal Spreading as Defective Gestural Deactivation
نویسندگان
چکیده
Nasal spreading (also called nasal vowel-consonant harmony) is a process by which a nasal segment in a word triggers nasalization of its surrounding segments. This paper proposes a reanalysis of this phenomenon using gestures as the units of phonological representation in order to more accurately capture its crosslinguistic typological patterns. Nasal spreading proceeds unboundedly, potentially resulting in spreading of nasality throughout an entire word. However, it is also common for the spread of nasality to be arrested by glides, liquids, or obstruents, a property known as blocking. This is exemplified in Warao (isolate; Venezuela), in which nasality spreads progressively from a triggering nasal consonant or vowel, affecting following vowels, glides, and glottal consonants (1a-d) but is arrested by liquids and obstruents, as in (1e-h) (Osborn 1966):

Ultrasound Study of Gestural Timing in Mandarin Vowel-Nasal Production
The present study uses ultrasound in combination with acoustic analysis to examine how a tongue gesture is timed in relation to acoustic syllable duration in Mandarin vowel-nasal production. The results show that gestural timing is relevant to both tongue and syllable positions; for example, anterior gestures such as the tongue tip rising tend to occur closer to syllable peripheries than open o...
متن کاملInter-gestural timing in French nasal vowels: A comparative study of (Liège, Tournai) Northern French vs. (Marseille, Toulouse) Southern French
This paper provides a comparative gestural account of nasal vowels in Southern French (Marseille, Toulouse; France) and in Northern French (Liège, Tournai; Belgium). Timing measurements based on acoustic data confirm a different temporal organisation of the gestures between the two regiolects. We also report on statistical comparisons between phonetic events (such as duration of the SF ‘nasal a...
متن کاملGestural overlap and C-center in selected French consonant clusters
Inter-consonantal cohesion in French word-initial CC clusters is investigated in light of recent proposals of gestural coordination. Specifically, the timing of lip and tongue movements of C1/l/ and C1/n/ productions, with C1 being one of the consonants /p, f, k/, of two speakers were studied using electromagnetic articulography (EMA). In French, C/l/ clusters occur frequently in word-initial p...
متن کاملPlace vs. Stricture in Spanish Nasal Assimilation
In this paper we investigate patterns of place and stricture assimilation of Argentine Spanish nasals in order to test two competing models of phonological representations of place and stricture features (or tract variables). Electropalatographic (EPG) data from four speakers of Buenos Aires Spanish reveal that nasal assimilation before coronals within words (e.g. in /kanta/, /kansa/, /anʧa/) i...
متن کاملReinterpreting Transparency in Nasal Harmony*
1 . Introduction In this paper I examine crosslinguistic variation in nasal harmony. Three kinds of segment behavior are observed: target segments become nasalized in nasal harmony (/na/ → [na)]), blocking or opaque segments remain oral and block nasal spreading (/nata/ → [na) ta]), and transparent segments remain oral and do not block nasal spreading (/nata/ → [na) ta) ]). The membership of th...
