Articulation And Acoustics Of Kannada Affricates: A Case Of Geminate /ʧ/, Alexei Kochetov, N. Sreedevi
Articulation And Acoustics Of Kannada Affricates: A Case Of Geminate /ʧ/, Alexei Kochetov, N. Sreedevi
Alexei Kochetov
Affricates have been observed to be problematic in phonological acquisition and disordered speech across languages, due to their relatively complex spatial and temporal articulatory patterns. Remediation of difficulties in the production of affricates requires understanding of how these sounds are typically produced. This study presents the first systematic articulatory and acoustic investigation of voiceless geminate affricate /ʧ/ in Kannada (a Dravidian language), compared to the palatal glide and the voiceless dental stop. Ultrasound data from 10 normal speakers from Mysore, India revealed that /ʧ/ is produced with the tongue shape intermediate between the palatal glide and the dental stop, and …

Abstract: This study investigates the production of geminate retroflex stops in Kannada using a combination of ultrasound and articulography. Data obtained from 10 native speakers of the language show that the retroflex gesture is dynamically complex and asymmetrical, involving an anticipatory retraction of the tongue tip, followed by the raising of this articulator towards the hard palate, and subsequent rapid flapping-out movement during the closure and the release. The retroflex constriction and the forward movement appear to be facilitated by the simultaneous fronting of the posterior tongue body, flattening of the anterior tongue body, and lowering of the jaw.
