ACOUSTIC
HIGHLIGHTING
“Motherese” (a form of acoustic highlighting) is speech used
by parents/caregivers in talking with young children to help them in learning
language. Its use is extended in
communicating with a child who is hearing impaired to increase the audibility
of language. As a child learns to
listen, the aim is to progress toward a more normal, less highlighted mode of
communication.
Examples of acoustic highlighting are as follows:
MORE AUDIBLE
(for a beginning child)
|
PROGRESSING TO
|
LESS HIGHLIGHTING
(for a child who is listening well)
|
No background noise
|
Increased background noise
|
|
6” from hearing aid or cochlear implant
|
Increased distance from hearing aid or cochlear implant
|
|
Slightly slower rate
|
Normal rate
|
|
Increased pitch variation (sing what you say)
|
Normal rhythm
|
|
Clearer enunciation (use of “clear” speech)
|
Less clear and/or unfamiliar voice
|
|
Increased repetition
|
No repetition
|
|
Greater acoustic contrast (vowel variation, rhythm
contrast, number of syllables)
|
Less varied (minimal pairs, same syllables, similar
rhythm)
|
|
Simpler language with shorter phrases
|
Complex sentences
|
|
Emphasis on key words
|
No emphasis on key words
|
|
Emphasis on unaccentuated words (prepositions, articles,
verb tenses, pronouns)
|
No emphasis
|
|
Word position in sentence:
End of sentence
|
Middle of sentence
|
Beginning of sentence
|
Closed set
|
Open set
|
However, having reached the goal of less highlighting it
must be remembered that there are many acoustic environments where acoustic
highlighting may continue to be necessary as it is with those who have normal
hearing.
