- It can support the development of language and reading skills.
- It enhances the development of fluent colloquial English skills.
- It provides access to oral language phonology.
- As a bonus supports speech and speechreading skill development.
|
|
3
|
- Additionally, for language fluency and literacy, the individual must
have a knowledge of the syntax and grammar of the language.
- As it is used in regular communication, CS provides access to this
knowledge through.
|
|
4
|
- Research indicates that a depth of knowledge of the vocabulary in
addition to the range (i.e., knowing multiple words for a concept and
multiple concepts for a word) is critical for these skills.
- CS provides this access by allowing fluent communication in a range of
settings.
|
|
5
|
- CS can be used by hearing parents to communicate without having to
simplify their vocabulary as well as allow them to read children’s books
such as Dr. Seuss that include nonsense words
- “There’s a wocket in my pocket”.
- This is important in developing language facility that is critical to
pre-reading skill development.
|
|

|
- Cued Speech can be used for specific interventions and training to
- Clarify phonemes the child is seeing/hearing
- Help the child target sound s/he is trying to produce
- Learn grapheme-phoneme associations
- Develop basic reading skills
|
|
7
|
- Research indicates that children cued to from an early age at home and
in school performed accurate phoneme-grapheme decoding (like hearing
children)
- Those cued to later and only at school and those using only signs did
not.
- Those cued to only at home performed better than signers, but less well
than those cued to in all environments.
- This effect of early, consistent cueing was seen in studies of spelling
skills as well.
|
|
8
|
- Research compared reading achievement of deaf Cuers with severe hearing
loss to those with profound hearing loss.
- Profound Ss did better!!!!!!!!!
- Due to decreased amount of Cueing to the severe Ss?
- Implications for CIs.
|
|
9
|
- While they exist on a continuum, all children with hearing loss miss
speech information.
- Used as a communication method CS provides ongoing access to the
vocabulary and the phonemic structure of the vocabulary.
- It also provides modeling and exposure to the syntax and grammar of the
language.
|
|

|
|
|
11
|
- The CI allows the child access to sound.
- The ability to use this sound to discriminate speech is a skill that
must be learned.
|
|
12
|
- It does not make the child “hearing” or even (although on audiological
measures they may look like it) hard of hearing.
- CI’s do not produce “normal” hearing
- Even the best maps tend to provide 25 – 30 dB
- The “sounds” are analyzed representations filtered to emphasize speech
sounds, but not all acoustic information is conveyed.
|
|
13
|
- Studies of speech reception of CI users indicate gaps in speech
perception
- Experienced CI users ages 8 – 10 using audiotapes of nonwords (so they
could not use speechreading or their vocabulary to support their
perception).
- Only 5 % of responses were accurately produced.
- Some of this may have been speech accuracy.
- Even considering speech, this suggests inaccurate auditory
perception.
- 64% had the correct number of syllables
- 61% had the correct placement of stress.
- Carter, Dillon & Pisoni (2003)
- Two years after activation, mean recognition of consonants was 71%
- Vaelimaa, Maeaettae, Loppoenen, & Sorri (2002)
|
|
14
|
- In addition to the audiological limitations of the CI, it does not
provide auditory information in all situations.
- At night when the lights are out
- Bath time
- Swimming
- When it’s broken (panic!!!)
- On plastic slides and some other playground equipment
- Any time the CI processor can’t be worn or is not useful.
|
|
15
|
- Also, for most implantees, information from the non-implanted side is
degraded and more difficulty to “hear”.
- Noise is extremely difficult to filter out, especially speech-based
noise.
- Classrooms have notoriously bad acoustics
- “children with hearing impairment obtained perception scores of only
60% as compared to 83% for the normal hearers. In acoustical
conditions more commonly reported in the classroom (SNR = +6 dB; RT =
1.2 seconds), children with SNHL obtained perception scores of just
11% as compared to 27% for children with normal hearing.”
- http://www.phonicear.ca/resourcefiles/PhonicEar-ClassroomAcousticsForChildrenWithNormalHearingAndWithHearingImpairment.pdf
- Group interactions are more difficult, especially when others in the
room or nearby rooms are talking.
|
|
16
|
- Even in the best of circumstances, children using CI’s will depend to
some extent on visual cues and their knowledge of the language to
support their auditory language reception.
|
|
17
|
- One simple answer is to Cue.
- We all know that CS provides clarification of the phonemic information
on the lips and mouth.
- This clarification can be used by CI recipients to support the auditory
information that is obtained via the CI.
- CS addresses all of the factors that have been identified as predicting
CI success.
|
|
18
|
- Research indicates that success in developing speech discriminate is in
part dependent on:
- Pre-existing knowledge of the language being spoken.
- Vocabulary
- Syntax & Grammar
- An internal model of the phonology of the language.
- AKA “auditory memory”, BUT, previous hearing is not required if the
child has an internal model of the phonology of the language without
hearing (CS).
- Some research suggests that temporal (sequential) processing
“contributes to speech perception by cochlear implant users” (Fu, 2002)
|
|
19
|
- Pre-existing knowledge of the language
- As we have already seen, CS allows for appropriate development of
knowledge of both the structure (grammar & syntax) and vocabulary
of the language.
- Studies indicate that profoundly deaf Cue Kids do better than those
with less severe hearing losses (those more like CI users).
- This is counter to the norm, where reading and oral language
correlate positively with residual hearing.
- Likely because people Cue more consistently with the kids with less
residual hearing.
|
|
20
|
- Remember, these kids are learning the language at the same time that
they are trying to develop skills (learning to “hear”) with the CI!!!
- They need ongoing unambiguous access to the language during this
process, otherwise, their language skills as well as their listening
skills will likely be negatively impacted.
|
|
21
|
- Internal model of the phonology of the language.
- CS provides users with an internal model of the phonology of the
language.
- The internal model allows the CI user to attach new acoustic
information provided by the CI to the pre-existing internal model of
phonology based on CS
- This is best achieved by the
individual experiencing concurrent Cueing and auditory stimulation
|
|
22
|
- Associative learning (Pavlov's dog)
- Every time the child hears the phoneme and is alerted to the target
phoneme via CS, his ability to accurately identify that phoneme is
enhanced.
- Research with cognitive rehabilitation indicates that it takes hundreds
of reinforced (CS confirmation) trials before the brain learns how to accurately
and automatically code the information.
|
|
23
|
- Cognitively, the development of the ability to accurately and
automatically decode the received information is critical.
- If it is effortful (not automatic),
- it will fatigue the individual, and they will miss information.
- cognitive resources will have to be used to decode the information and
will be unavailable for comprehension and integration of the input.
- Similar to parrot reading – the child may be able to say and even
understand the words, but not the sentence.
- If it is too effortful, they will quit trying.
- If it isn’t accurate, miscommunication occurs.
|
|
24
|
- Some research suggests that temporal (sequential) processing
“contributes to speech perception by cochlear implant users” (Fu, 2002)
- Multiple studies have demonstrated that CS enhances verbal sequential
processing.
- This correlates positively with reading comprehension as well as
listening comprehension.
|
|
25
|
- Even children with mild to moderate hearing loss (including CI users)
miss things.
- Important aspects of English are vulnerable to mild loss
- possessives & plurals (/s/), tense identifiers (/d/, /t/, /id/),
etc.
- Articles and connectors are often missed or slurred in conversation.
Children often hear telegraphic speech.
- Listen to them! They say what they hear.
- “Joe and I are going to the store” may be heard as “Joan Ire goanuhth
store”
- Small words are often swallowed as we talk
|
|
26
|
- Although consistent Cueing is preferable, the child may benefit from
using Cued Speech to clarify individual words
- When the child has mispercieved a word, you can cue it to clarify the phonemes
involved.
- Also excellent for spelling tests to ensure that the child is
see-hearing the word accurately.
|
|
27
|
- New vocabulary should be introduced using Cues to ensure that the child
knows what you really said.
- Ambiguous information is both confusing and frustrating. You can’t
learn a word you can’t perceive clearly.
- Children may assume “bet” and “bit” really are the same thing.
- They will also have a better idea of what phonemes to target for their
speech.
|
|
28
|
- Deaf/HOH children typically have difficulty with phonemic awareness, and
Cueing can be used to develop these skills
- A key concern in these children’s development of phonological awareness
skills is their impaired ability to discriminate individual phonemes of
the language
- E.g., /b/ and /d/ may be indistinguishable even for HOH children.
|
|
29
|
- CS clarifies the ambiguous auditory signal
- Phonemic awareness activities normally presented using speech can be
done using Cued Speech.
- The only adaptation needed is for the parent/teacher/therapist (and,
preferably, the child as well) to Cue.
- This automatically clarifies the phonemic information for the child.
|
|
30
|
- Audiological myths and bias
- Fear of interfering with listening skill development.
- It’s too much work.
|
|
31
|
- In the end, our job is to facilitate the child’s education and language
development.
- Cueing does this with minimal added cost.
- It also makes their lives easier, as they are not constantly struggling
to understand what is said and suffering from missed information and
miscommunication.
