    A comparison of a new prototype Tickle Talker with a Tactaid 7
    Galvin, Karyn L. ; Ginis, Jan ; Cowan, Robert S. C. ; Blamey, Peter J. ; Clark, Graeme M. ( 2001)
    This study compared the speech perception enhancement provided by two multichannel tactile aids: a new version of the Tickle TalkerT™ and the Tactaid 7. The subjects' impression of benefit was also examined. In an AB pattern, six adults with hearing impairment used each device daily for approximately 18 weeks and attended 12 training sessions. When tactile information was provided, the group demonstrated a significant enhancement for the perception of words (mean 17.2%) and phonemes (mean 12.9%) in monosyllabic word lists, words in sentences (mean 14.2%) and speech tracking (mean 7.7 wpm). The Tactaid 7 provided a significantly greater enhancement for the perception of words (21 % versus 13.4%), phonemes (16.7% versus 9.1%) and some speech features in monosyllabic word lists. Subjective ratings were slightly higher for the Tactaid 7, and four subjects preferred this device. Either device may be suitable for those not able or willing to have a cochlear implant.

    Cochlear implants for congenitally deaf adolescents: is open-set speech perception a realistic expectation?
    Sarant, J. Z. ; Cowan, R. S. C. ; Blamey, P. J. ; Galvin, K. L. ; Clark, Graeme M. ( 1994)
    The prognosis for benefit from use of cochlear implants in congenitally deaf adolescents, who have a long duration of profound deafness prior to implantation, has typically been low. Speech perception results for two congenitally deaf patients implanted as adolescents at the University of Melbourne/Royal Victorian Eye and Ear Hospital Clinic show that, after 12 months of experience, both patients had significant open-set speech discrimination scores without lipreading. These results suggest that although benefits may in general be low for congenitally deaf adolescents, individuals may attain significant benefits to speech perception after a short period of experience. Prospective patients from this group should therefore be considered on an individual basis with regard to prognosis for benefit from cochlear implantation.
