Development of Lingual Displacement Independence at Babbling Stage
نویسندگان
چکیده
In this study, we recorded jaw movements and the acoustic signal of 15 babies of 8 to 12 months of age during babbling in order to assess the hypothesis whereby tongue gestures would be more independent from mandibular ones with age. Results corroborate our expectations. We have shown that increase in the amplitude of tongue gestures in the anterior/posterior dimension, in relation to vertical jaw movement, is noticeable in older babies. This reveals emergence of articulatory control in babies throughout the babbling stage

Intonation Development of a Taiwanese Child in Her First Year
This paper investigates the intonation development of an infant during the first year. Three stages include the goo stage (2-3 months), the canonical babbling stage (7-9 months), and the variegated babbling stage (10-12 months). Falling contour was found to be the most common intonation at the goo stage. Rising contour was found to be the dominant intonation both at the canonical babbling and t...
متن کاملCross-linguistic Patterns in Infant Babbling
Infants begin to vocalize very soon after birth, and they begin to babble about six months after they are born (Oller, 1980). The babbling stage is distinct from the previous phase of vocalizations in that sounds – or gestures in infants acquiring sign language – are now clearly organized in a syllabic structure. As such, these utterances are the infant’s first linguistic productions. In the wo...
متن کاملLingual Co-occurrence Constraints in Babbling: an Acoustical Study
Acoustical measurements of F2 transitions of 370 babbled CV sequences showed that places of articulation for consonantal closure correlate highly with vocalic tongue frontness/backness. This finding is interpreted as a confirmation of the MacNeilage and Davis Frame/Content theory of speech development.
