    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.

    Improved electrotactile speech processor: Tickle Talker
    Cowan, R. S. C. ; Galvin, K. L. ; Sarant, J. Z. ; Millard, R. ; Blamey, P. J. ; Clark, Graeme M. ( 1995)
    The Tickle Talker, an eight-channel electrotactile speech processor, has been developed from continuing research at the University of Melbourne. 'The development of the device has focused on production of reliable speech-processing hardware, design of cosmetically and ergonometrically acceptable electrode transducers, implementation of acute and chronic biomedical studies demonstrating device safety, design and testing of alternative speech-encoding strategies to provide benefit to speech perception and production, and design and testing of appropriate training methods for optimizing benefits. The Tickle Talker has been shown to provide benefits in supplementing lipreading or aided residual hearing for hearing-impaired adults and children. Improvements in speech processing have resulted in an increase in benefits to speech perception, and open the way for more flexible approaches to encoding speech input. Continuing development of the electrode circuitry has now produced a device that is robust and has an extended battery life. Safety studies have clearly demonstrated that there are no long-term contraindications to device use. The results suggest that the device has a role to play in rehabilitation programs for severely and profoundly hearing-impaired adults and children.
