LINA02H3 Lecture Notes - Lecture 3: Vocal Tract, Reduplication, Oneword
Document Summary
Infants can discriminate any potential linguistic contrast in any human language. After 6 months, babies begin to lose the ability to discriminate between sounds that are not phonemic in the language(s) they are acquiring: ex. Japanese-environment babies distinguish [l] and [r] until; 6 mos. English babies will always distinguish [l] and [r] Not directly tied to the language of environment: sounds of babble are universal, practice timing of sound combinations and execution of complex physical maneuvers in the vocal tract. Stages: 1 cv at a time; [ma] or [di[, then reduplicative [bababa] , [dududu, non-reduplicative babbling sequences more varied [dubadu] Characteristics: most frequent 12 sounds in the world"s languages make up 95% of sounds in babbling. Vowels: high-tense and low lax [i, u, a] (recall that these are the most common vowels in the world) Consonants: voices stops: [d, b, g, m]
