Features Flashcards
[±continuant]
sounds produced with free or nearly free airflow through the centre of the oral cavity are [+continuant]; other sounds including stops and nasals are [-continuant]
[±delayed release], [±DR]
in an affricate sound such as [tʃ] the tongue is slower in leaving the roof of the mouth than a stop like [t] on its own. only affricates are are [+delayed release]
[±nasal]
sounds produced with a lower velum are [+nasal], sounds that are oral and produced with a raised velum are [-nasal]
[±lateral]
all and only varieties of l are [+lateral], with air escaping along the lowered sides of the tongue, all other sounds are [-lateral]
[LABIAL]
represents the labial articulator, any sound produced with one or both of the lips
[±round]
a sound produced with the labial articulator may be produced by protruding the lips, such sounds are [+round], labial sounds made with no lip protrusion are [-round]
[CORONAL]
represents coronal articulator, any sound produced with involvement of the tongue tip or blade raised
[±anterior]
all coronal sounds articulated in front of the alveopalatal region (interdentals and alveolars) are [+anterior], coronal sounds articulated at or behind the alceopalatal region (alveopalatals) are [-anterior]
[±strident]
all ‘noisy’ coronal fricatives and affricates (s, z, ʃ, ʒ, tʃ, dʒ) are [+strident]; all other coronal frics and affrics (θ, ð) are [-strident]
[DORSAL]
represents the dorsal articulator, all sounds that are produced with the involvement of the body of the tongue, including all vowels, are [DORSAL]
[±high]
dorsal consonants (velars and palatals) and vowels produced with the tongue body raised from a central position in the oral cavity are [+high], sounds produced with a neutral or lowered tongue are [-high]
[±low]
vowels produced with the tongue body lowered from a central position in the oral cavity are [+low].
the feature [low] is not needed for consonants in English , but it can be used in other languages for uvular or pharyngeal consonants
[±tense]
vowels that are tense are [+tense], vowels that are lax are [-tense]
[±reduced]
the vowel schwa ([ə]) is a lax and exceptionally brief vowel and is therefore [+reduced]; all other vowels are [-reduced]
[±voice]
all voiced sounds are [+voice];all voiceless sounds are [-voice]
[±spread glottis] ([±SG])
all aspirated consonants and [h] are [+SG], all others are [-SG]
the use of this feature reflects the fact that aspiration occurs when the vocal folds remain open (spread) after the release of a consonant’s closure
[±constricted glottis] ([±CG])
all sounds made with a closed glottis are [+CG], all others are [-CG], in english only the glotta stop [ʔ] is [+CG]
[±consonantal]
sounds that are [+consonantal] are produced with a major obstruction in the vocal tract
all consonants are [+consonantal] except for the glottals [h] and [ʔ] which are produced in the glottis rather than the vocal tract, like glides and vowels they are [-consonantal]
[±syllabic]
sounds that can act as syllable nuclei are [+syllabic]; this includes vowels, syllabic liquids, and syllabic nasals, all other sounds are [-syllabic]
[±sonorant]
all and only those sounds that are ‘singable’ are [+sonorant]; they include vowels, glides, liquids, and nasals (even if the sounds are devoiced)
all non-singable sounds (namely obstruents) are [-sonorant]
