Oral Language Development

Similar Routes in First and Second Languages

First Language Development• Birth to Three months

– Vocal Play (vowel-like, rising and falling volume + pitch, full range of sounds gradually fade)

– Distinguish verbal from non-verbal sounds– Within a few days after birth babies are highly

responsive to speech sounds– Preverbal infants can discriminate between /b/

and /p/

The Brain is a pattern detector...

.... It keeps track of recurring segments of speech and continually updates guesses about language and its underlying rules within the context of the speech act.

Three to Six Months

Vocal Play [consonant sounds: lips(/m/b/p/); tongue (/t/g/l/)]

Six to Nine Months

Babbling [Repeated sound combinations, consonant/vowel combinations (mama,baba)]

Emergence of first true word (holding meaning) around eight months.

Nine to Twelve Months

Receptive language much more noticeable

Deaf children stop babbling and rarely produce words

Twelve to Fifteen Months

Jargoning (babbling with tone and inflection - sentence-like)

One-word stage• (use different intonation to signal different

meanings)• multi syllabic words become reduplicated button,

baby, butter - bubba• single syllable words become consonant/vowel

combination duck - du Approx. 3 words*

Fifteen to Eighteen Months Imitation with more recognizable

words - continued jargoning Approx. 22-25 words*

Eighteen to Twenty-Four MonthsPhrases (short and often ungrammatical

combinations, often difficult to understand)Beginning use of pronouns (but still refers

to self by name)Begin to acquire regular patterns of

pronunciation (after approx. 50 words)Approx. 272 words*Two-word stage.

Twenty-Four to Thirty-Six Months (2-3 yrs) Sentences/Questions (2-3 word

sentences to 4-5 words) Accurate discrimination of speech

sounds develops Why, What, Where (for information,

understanding contexts for use and conversational turn-taking)

Approx. 896 words

Thirty-Six to Forty-Eight Months (3-4 yrs)

Paragraphs

Non-fluency possible in expressive language (to approx. 5 yrs. of age)

Approx. 1870 words*

Forty-Eight to Sixty Months (4-5yrs)Nearly full control of grammarContinued growth in Metalinguistic

awareness, Literacy and “Communicative Competence” [grammatical; sociolinguistic: requests, suggestions, complaints; discourse: narrative, argumentation; strategic competence] continues through life span.

Approx. 2289 words*

Caveat

• First and second language learners [are]... different in what they bring to the learning situation but similar in their capacity to acquire language and similar in what they end up with through the acquisition process provided that there is equal amount of time and the learning contexts are similar (Hakuta, 1986, p. 132).
