2. Definitions:Language: Communication of thoughts
and feelings through a system of signals,
such as voice sounds, gestures, or
Speech: The act of expressing or
describing thoughts, feelings, or
perceptions by the articulation of words
3. Almost every human child succeeds in learning languageWe tend to take the
process of language learning for granted,
language seems like a basic instinct as
breathing or blinking
In fact, it is the most
complex ability that a human
being will ever master.

Infants prefer the language that resembles the
speech of theirmothers.
Prefer their own mother’s voice, as opposed to that
of other women.

Based on three earlier developments:
• Infant’s growing ability to record the sounds of
• Ability to control vocal productions that occur
in the late stages of babbling.
• General growth of the symbolic function, as
represented in play and imitation.
7. The forms of early words often deviate radically from the adult standard. Children tend to:•Drop unstressed syllables, producing
hippopotamus as poma.
•Repeat consonants, producing water as wawa.
•Simplify and reduce consonant clusters,
producing tree aspee.

Children tend to be conservative and unsure about
how to use verbs productively until about age 5

Babbling stage. Vocalizations begin to
reflect the ambient language.
11 to 18 months
Auditory discrimination of speech is tuned to
the ambient language
19 to 24 months

phonetic ability to learn many new words.
25 to 36 months
Continued growth in phonetic inventory,
along with vocabulary and syntax.
Stuttering is often first noticed at
about this age
3 to 4years
Almost all vowels are mastered by this age,
along with a number of consonants.
4 to 6years
Closing in on phonemic mastery, with the
exception of fricative (noise) sounds.
6 to 9years
Phonemic mastery typically completed, but
refinements in speech production continue.
Speech development is complete, but
developmental changes can be observed
(E.G., Voice change in adolescence)
