5/06/2014 ALEXANDER GRAHAM BELL CONVENTION “MAGIC MADE REAL: CELEBRATING OUR HERITAGE, TRANSFORMING OUR FUTURE” A LING CONSORTIUM DISCOVERY SESSION FUNCTIONAL AND PRACTICAL APPLICATION OF LING’S STRATEGIES: A GLOBAL PERSPECTIVE A LING CONSORTIUM DISCOVERY SESSION Introduction Dimity Dornan, A.O., Ph.D., LSLS Cert AVT Hear and Say, University of Queensland, Australia and Griffith University, Australia Ling Consortium _______________________________ Ling Consortium _____________________________ • International consortium of professionals • Developing and delivering globally recognized university-based courses on teaching listening and spoken language • Focused on bringing speech and hearing to children with hearing loss • Enabling a life of abundance • Named in honor of the foundational work and extraordinary contributions of the late Dr. Daniel Ling, O.C., a pioneer of Auditory-Verbal practice for children with hearing loss. Global Vision: Children and adults with hearing loss will reach their full potential through listening and speaking. Global Mission: The Ling Consortium is helping more children to speak and hear thanks to a coordinated worldwide effort. Who was Dr. Daniel Ling and why are his theories and practices still relevant today? ____________________________________ • One of the pioneers of listening and spoken language for children with hearing loss – Auditory-Verbal practice. • Audiologist and internationally recognized authority on teaching speech to children who are deaf/hard of hearing. Objectives: Participants will… • examine how Daniel Ling’s legacy has transformed the field of listening and spoken language for children and adults with hearing loss • appraise how his legacy exists in harmony with knowledge from neuroscience and 21st century hearing technology • analyze current research in the field of speech development 1 5/06/2014 Objectives: Participants will… • appraise how Daniel Ling’s legacy has influenced practitioners from around the world • Discuss future influences of Daniel Ling’s legacy FUNCTIONAL AND PRACTICAL APPLICATION OF LING’S STRATEGIES: A GLOBAL PERSPECTIVE 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) 2 5/06/2014 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).

Am J Speech-Lang Pathol, 21; 342-353, 2012 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). FIGURE 6.

Consonant production accuracy in young cochlear implant recipients: Developmental sound classes and word position effects. Am J Speech-Lang Pathol, 21; 342-353, 2012 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).

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. 1996 - Cochlear Implants . 7 5/06/2014 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 1st 5 maps – post switch-on Nupur’s maps • 1st Map • 4th Map • 2nd Map • 5th Map • 3rd Map • Overview THANK YOU Thank you! AURED-Aural Education for Hearing Impaired Children, Affiliated with AG Bell www.aured.org …continued 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?

Korea in the World AV T The first cochlear implantation was done at 1989 and the surgery cases increased quickly by late 1990s and early 2000s. AVT was introduced along CI AV T It has been introduced by well-known AVTs like Warren Estabrooks, Dimity Dornan, Judy Simser, Ann Fultcher, etc. They offered lectures and supervision mainly for the speech AV T therapists. Special schools and centers which deal with mainly hearing aids resisted to the concept and techniques of AVT at the beginning.

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.

(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 spectrum (Speech Banana) Phonetic Level Evaluation Phonologic Level Evaluation Speech Teaching System based on speech acoustics, prerequisite speech skills, practice and carryover into spoken language Ling’s Legacy “A life of abundance” for children with hearing loss everywhere, will continue to be transformational well into the future - truly “Magic Made Real”. 14
