Features Of An Obstruent

An obstruent is a consonant sound which is formed by obstructing the airflow and causing air pressure in the vocal tract. This is articulated either with a total closure or a partial closure of the vocal tract causing friction. Under obstruents we find Plosive, Fricatives and Affricates. All these features have acoustic properties associated with them. Tenyidie is a highly consonant-based language meaning that consonants makes up most of the words thereby making the obstruent section a large section since obstruents dominate most of Tenyidie’s inventory. The velar plosive / k / in particular is the phoneme that is used in the initial position in most words. Tenyidie’s obtruents contains complicated articulations with primary and secondary …show more content…

They are also called stops but we will be referring to them in this chapter as plosives. All plosives are articulated by completely closing the vocal tract causing the airflow to build up and then suddenly opening the closure resulting in a plosion. During this closure the mouth remains completely closed. The burst is followed by a short frication produced when air pressure behind the closure is suddenly released. This would consequently be followed be voicing or aspiration. The remaining low frequency energy is seen as the ‘voicing bar’ at the bottom of a …show more content…

They have a low frequency for F1 with rapid formant transitions followed by a released burst. With the secondary articulations, most of the phonemes would be followed by aspiration, rhoticised and palatalization. The place cues for plosives include the centre frequency of the turbulence occurring at the release and the locus frequency for the second and third formant transitions. Cues for plosives also include voice onset time (VOT), burst with a short burst of silence since the vocal tract is blocked and duration of the preceding vowel. The signature of plosives is an almost instantaneous passage from little or no acoustic energy to a short burst of high energy in a wide frequency band. The plosives, like the fricatives, may be accompanied by voicing. During the closure, the only source is voicing. Otherwise in the case of voiceless plosives, the closure may be completely silent. Simply put, there are three principal cues to the place of articulation for voiced and voiceless plosive
