A LING CONSORTIUM DISCOVERY SESSION
Summary of Current Research on Speech
Development
Elizabeth Fitzpatrick
University of Ottawa
Children’s Hospital of Eastern
Ontario Research Institute
The way we were….
Speech production
Speech intelligibility
• Speech development in children with hearing loss
is highly susceptible to delays and disorders.
• Severity of hearing loss affected the extent of
speech disorders (Boothroyd, 1969; Levitt, 1987).
• Infants produced less and later canonical babbling
and more limited range of consonants (e.g., Oller &
• For children with severe to profound loss,
about 20% of words were intelligible to
unfamiliar listeners (Markides, 1979; Smith, 1975,
Eilers, 1988, Lynch et al., 1989; Stoel-Gammon, 1988; YoshinagaItano, 2000).
• Phonetic repertoires of infants with severeprofound loss were very restricted; e.g., fewer
multisyllabic utterances (e.g., Kent et al., 1987; Lach, Ling,
et al.,
Osberger, 1992).
• Little improvement after ~age 8 yrs
(Smith, 1975; McGarr, 1987).
1970; Stoel-Gammon & Otomo 1986)
Early speech development:
Cochlear implants
The way we are…
• Access to speech spectrum results in many more
children with intelligible speech
– ‘Typical’ children with any degree of hearing loss
are expected to develop highly intelligible speech.
• Predictors of speech development:
– Cognitive abilities (Geers et al., 2002;
Tobey et al., 2003)
– Auditory experience (e.g., Geers, 2004)
– Integrity of the oromotor system
– Other language disorders or additional disabilities
• Children with CI achieved majority of speech-like
utterances after 12 m of auditory experience
compared to 18 m experience for peers with normal
hearing. (Ertmer, 2013).
• Consonant production accuracy was delayed in
children with CI with 24 m experience (Ertmer et al.,
2012; Leigh et al., 2013).
• Children with CI showed consonant acquisition
patterns similar to peers with normal hearing when
CI age was similar to chronological age of peers
(Spencer & Guo, 2012).
• The phonetic complexity of early babbling is related
to later speech and language skills
(Walker
et Bass-Ringdahl, 2008)

Early speech development
Children with hearing loss
Speech sound accuracy:
Children with cochlear implants
• At 12 m, children with HL (>50 dB) showed fewer
consonant multisyllabic utterances , fewer fricatives/stops
and more restricted vowel tongue positions (McGowan et al.,
2008).
• At 10-24 m, children with HL showed delays in consistent
canonical babble and in consonant development (Moeller et
al., 2007).
• At age 24 m, children with mild to severe HL had vowel
production similar to peers with normal hearing but weaker
consonant production (Ambrose et al 2014).
• At age 3-4 y, consonant clusters were within the expected
range for children with normal hearing (Fulcher et al., 2014).

by the CI and TD groups for each developmental sound class.

Speech sound accuracy :
Children with cochlear implants
Speech production
 At 3 yrs, speech production on GFTA-2 = mean
standard score of 74 (late) to 101 (early) (standard
score) and from 86 to 106 by age 5 yrs (Fulcher et al.,
2013).
 At 3 yrs, speech production on DEAP = median
standard score of ~80 (consonants) to ~85(vowels)
(Ching et al., 2013).

 At 4-5 yrs, speech production on GFTA-2 = mean
standard score of 93 for children with HA and 80 for
children with CI, and 107 for peers with normal
hearing. (Fitzpatrick et al., 2011).
Speech production scores
Speech intelligibility
• Over 90% of children with profound loss develop
intelligible speech (Yoshinaga-Itano, 2008).
• At age 5.5 yrs, children with CI implanted before 2
yrs had intelligibility scores of > 80% (Habib et al.,
2013)
• For adolescents with CI, speech intelligibility
scores (McGarr sentences) ranged from 81 to
88% (Tobey et al., 2010).

Conclusions
• Children with hearing loss still have reduced
access, later access, and reduced auditory
experience compared to peers =
– they are still at risk for speech difficulties
• “Improved hearing sensitivity does not, by
itself, guarantee the ability to discriminate
between sounds or to interpret speech for oral
communication purposes.”

with 16 and 17 years experience in teaching deaf
children.
 Enrolled today- 700 of which 550 are CI recipients, from 90 cities
in India and 16 neighbouring countries
 80% receive free therapy and mapping
 40% with additional challenges
 95% integrated
 Age group - 4 months onwards
Established a Satellite centre in Hyderabad. Affiliate
centres in Delhi and Kenya.
Introduction of Daniel Ling and AVT
1981 & 1991 – Ling Workshops + 6 hours of
mentoring by Ling in individual therapy sessions.
1986 – 1991, mentored in AVT by Alan Kelly, AVT
Cert., Australia, who studied under Ling for his
MSc
An in-depth study of Ling’s Foundation of Spoken
Language & Speech & the Hearing Impaired Child
– applied in Language, Speech and Auditory
development of children at AURED.
 17 therapists and 4 audiologists
 Total Staff-22
Introduction of Daniel Ling and AVT
Speech Evaluation chart has been adapted and
modified for additional consonants unavailable
in the English Language.
Special emphasis on Ling’s Speech Acoustics
AURED partners a University course in AVT for
graduates in Sp. Education.
The Aziza Grid
Dearth of tools to explain complex terms of
mapping parameters.
 The Aziza Grid was developed primarily to
give a visual picture of the map and to
enhance communication amongst
audiologist/therapist/teacher and parent.
 Correlation between frequencies represented
in each electrode and Ling’s Acoustic phonetic
and phonologic levels.

Purposes of The Aziza Grid
 Serves several purposes: A tool for
Auditory Habilitation
a) Tracking children’s speech perception progress
post switch-on/activation
b) Guidelines in setting appropriate auditory goals
c) Trouble-shooting
Purposes of The Aziza Grid
Maps may vary due to the category the
candidate falls into :
Adults, pre-lingual. post-lingual, older
children, infants, anatomical deformities,
medical side effects
 After each Map, a child’s T and C levels
should be transferred to the Grid
 Auditory goals should be targeted with a
diagnostic approach

This tool is for the development of listening
skills. Follow Ling’s Hierarchy of listening.
 Listening cannot be separated from the
general process of communication through
speech and language. When setting goals,
therapist must correlate auditory
development with the candidate’s ability to
process language.
 Progress will depend on the category the CI
recipient falls into.
 The question now is – What’s next?

Ling’s Principles
 Korean has less phonemes in high frequency region
 Ling 6 Test is still useful
 Different symbols for
/a/, /i/, /u/
Professional Education Courses

The first Korean Auditory Verbal Therapist was certified
in 2004.
 Before and after the first Korean received certification,
many lectures and seminars were held in Korea.
 Several universities adopted the concepts and practices
of Ling’s methods.
 Yet, official education programs of Ling’s practices or
AVT was not opened in Korea.
 Currently, Ling’s concepts are being taught to emerging
clinicians at several universities and graduate schools.
Professional and Extended
Education Program is Coming
 Without official and fundamental education programs
teaching Ling’s practices and AVT, therapy for the deaf and
hard-of-hearing has been altered in some ways in Korea.
THANK YOU
 Nowadays, the practitioners are moving to form the
committee of AVT and open an official program teaching
AVT based on Ling’s work.
 We are expecting to gather and share as well as learn and
practice AVT, so that many innovative idea and practices
can be facilitated in Korea.

Who was Dr. Daniel Ling and why are
his theories and practices still relevant?
• Trained with the Ewings in England and
emigrated to Canada. (Montreal Oral School
for the Deaf. McGill University.)
• Speech and the Hearing-Impaired Child:
Theory and Practice (1976, 2002).
• Foundations of Spoken Language (1989).
• Aural Habilitation (with A. Phillips Ling 1978)
• Ling Speech Cards (now available through
John Tracy Clinic)
• Numerous articles and book chapters.
Ling & Current Best Practices
Foundation: Hearing and Audiology
 Maximize Audition
 Emphasis on auditory strategies - visual and
tactile used later if needed - then put back
into hearing
Ling used knowledge of speech acoustics &
perception (what the child hears) to drive his
model for teaching speech production (what
the child says).
Ling & Current Best Practices
The Ling Thing
Early Identification and Intervention
38 years of Ling
• Addressed the link between
Speech Perception and Speech
Production
• Children SPEAK the way they HEAR
• Evaluate both what they can HEAR
and what they can SAY
- child must be well aided as early as possible from the first few weeks/ months of life
~ Developmental Approach
~ Parent Guidance
(Ling Model: Remedial hierarchy of learning
speech for older children. Can be adapted for
developmental approach.)
Major Contributions
Ling Six Sound Test: m, oo, ah, ee, sh, s,
Determine access to sounds across the speech
