    The Tickle Talker: a speech perception aid for profoundly hearing impaired children [Abstract]
    Cowan, Robert S. C. ; Sarant, Julia Z. ; Galvin, Karyn L. ; Alcantara, Joseph I. ; Blamey, Peter J. ; Clark, Graeme M. ( 1990)
    Fifteen prelingually profoundly hearing-impaired children participated in speech perception training and evaluation, to assess potential benefits from use of the Tickle Talker. This device, a multichannel electrotactile speech processor, developed by Cochlear Pty. Ltd. and the University of Melbourne, presents speech as a pattern of electrical sensations felt on the fingers. The eight small electrodes are located over the digital nerve bundles, on both sides of the four fingers of the non-dominant hand. Speech processing hardware is similar to that used in the 22-channel cochlear implant. In the encoding strategy, second formant frequency (F2) is presented as electrode position, speech waveform amplitude as stimulus strength, and fundamental frequency (FO) as rate of stimulation. Each child participated in an ongoing training program involving clinicians, teachers and parents. The evaluation program included measures of sound and speech detection thresholds, and discrimination of speech features, words and open-set sentences. Both individual and mean scores for all the children demonstrate significant improvements in speech perception scores when input from the Tickle Talker is combined with either aided-residual hearing, or aided residual hearing and lipreading. These results are consistent with those previously reported for profoundly hearing-impaired adults using the Tickle Talker, and indicate that children are able to integrate speech information provided through the tactual modality with information from vision or residual hearing.

    A clinical protocol for multiple electrode cochlear implants in children [Abstract]
    Dowell, R. C. ; Busby, P.A. ; Roberts, S. A. ; Clark, Graeme M. ; Nienhuys, T. G. ; Blamey, P. J. ; Tong, Y. C. ( 1986)
    A clinical protocol for an experimental study to evaluate the speech perception and production, and communication skills using the multiple electrode cochlear implant in pre-adolescent children has been developed. A single-subject time-series design has been adopted to regularly assess these abilities. During the pre-operative stage the subject's current hearing aids or tactile device are used, and for the post-operative stage the Nucleus multiple electrode intracochlear implant. Training is provided in both stages of the study. Also included in the pre-operative stage are the audiological and medical evaluations to determine whether the subject meets the selection criteria. Speech perception and production, and communication skills are assessed from a large selection of language and developmental-age appropriate materials. Psychophysical studies are also undertaken to measure the subject's abilities to discriminate simple stimuli differing in electrical parameter values.

    Studies in tactile speech perception using the University of Melbourne Tickle Talker [Abstract]
    Galvin, K. L. ; Cowan, R. S. C. ; Blamey, P. J. ; Oerlemans, M. ; Ginis, J. ; Mavrias, G. ; Moore, A. ; Lu, A. ; Millard, R. ; Clark, Graeme M. ( 1998)
    During the past four years, a series of studies have been undertaken investigating the perception of speech presented through the tactile modality. These studies formed part of a project to develop an effective and safe electro tactile speech perception device for those children and adults requiring additional communication assistance to that provided by hearing aids, but unable to benefit from cochlear implants.
