    The effect of language knowledge on speech perception: what are we really assessing? [Abstract]
    Sarant, J. Z. ; Blamey, P. J. ; Cowan, R. S. C. ; Clark, Graeme M. ( 1996)
    It is a common finding that many hearing-impaired children have poorer language skills than their normally-hearing peers of the same age. It is also logical to assume that the measurement of open-set speech perception in children with cochlear implants could be affected by limited receptive vocabulary and syntactic knowledge. Therefore, we may be significantly underestimating the speech perception abilities of some hearing-impaired children.

    Speech perception results for children changing from multipeak to SPEAK speech processing strategy [Abstract]
    Sarant, J.Z. ; DelDot, J. ; Dettman, S. ; Hollow, R. ; Skok, M. ; Seligman, P.M. ; Dowell, R.C. ; Gibson, W.P.R. ; Clark, Graeme M. ; Cowan, R. S. C. ; Pyman, B. ; Galvin, K. L. ; Shaw, S. ; Barker, E. J. ; Brown, C. ( 1996)
    In mid-1994, a new speech processing strategy termed SPEAK was introduced for the Nucleus Spectra-22 cochlear prostheses. To compare benefits in implanted children changing to the SPEAK strategy, speech perception in a group of twelve children from Melbourne and Sydney was evaluated. The children were assessed in quiet and in background noise.

    Effects of habilitation in background noise on speech perception in implanted children [Abstract]
    Cowan, R. S. C. ; Klieve, S. ; Galvin, K. L. ; Sarant, J. Z. ; Clark, Graeme M. ( 1996)
    Evaluation of a group of children using the Nucleus multichannel cochlear implant, evaluated over a two year period, showed that improvements to speech perception scores in poor signal-to-noise conditions could be achieved through use of the Speak speech processing strategy. The increases were noted particularly in perception of consonant place features in poor signal-to-noise conditions. However, overall scores were still lower than for hearing in quiet.

    Factors affecting speech perception in children cochlear 22-channel cochlear prosthesis [Abstract]
    Dettman, S. ; Hollow, R. ; Herridge, S. ; Rance, G. ; Larratt, M. ; Skok, M. ; Dowel, R.C. ; Pyman, B. ; Clark, Graeme M. ; Cowan, R. S. C. ; Galvin, K. L. ; Klieve, S. ; Barker, E. J. ; DeDot, J. ; Sarant, J. S. ( 1996)
    Since the implantation of the first children with the Nucleus 22-channel cochlear prosthesis in Melbourne in 1985, there have been rapid expansion world-wide in the number of children using this implant system. Longer-term experience with implanted children has led to improvements in paediatric assessment and management. Speech processing strategies have also been improved, resulting in a series of increases in speech perception benefits.

    Speech perception results for implanted children with different levels of preoperative residual hearing [Abstract]
    Galvin, K.L. ; Rance, G. ; Larratt, M. ; Hollow, R. ; Herridge, S. ; Skok, M. ; Dowell, R.C. ; Pyman, B. ; Gibson, W.P.R. ; Clark, Graeme M. ; Cowan, R. S. C. ; DelDot, J. ; Barker, E. J. ; Sarant, J. Z. ; Dettman, S. ; Pegg, P. ( 1996)
    Many reports have established that hearing-impaired children using the Nucleus 22-channel cochlear implant may show both significant benefits to lipreading, and significant scores on open-set words and sentences using electrical stimulation only. These findings have raised suggestions that severely or severely-to-profoundly deaf children might benefit more from a cochlear implant than conventional amplification.

    Speech perception results for the nucleus multiple channel cochlear implant in children and adults with residual hearing [Abstract]
    Brimacombe, J.A. ; Arndt, P.L. ; Menapace, C.M. ; Clark, Graeme M. ; Cowan, R. S. C. ; Dowell, R. C. ; Shaw, S. ; Gibson, W. P. R. ; Staller, S. ( 1996)
    Speech perception results for profoundly deaf children and adults using advanced speech processing strategies for the Nucleus multiple-channel cochlear implant have continued to improve, and are now better than those reported in research with severely-to-profoundly hearing-impaired people using aided residual hearing.
