    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.

    Development of an advanced electrotactile speech processor [Abstract]
    Cowan, Robert S. C. ; Blamey, Peter J. ; Glavin, K. L. ; Sarant, J. Z. ; Millard, R. ; Clark, Graeme M. ( 1992)
    Initial studies with a multiple channel electrotactile speech processor ('Tickle Talker') showed that profoundly hearing-impaired adults and children could achieve significant improvements on speech perception tests through use of tactual-encoded estimates of fundamental frequency, second formant frequency and amplitude envelope. Results showed that the device provided tactual cues which could be used to discriminate speech features such as vowel length and place, and consonant manner and voicing. However, discrimination of initial consonant voicing was not as consistent as for other features. Accurate discrimination of consonant voicing and manner (particularly high frequency information) is critical, since this Information is generally inaudible through hearing aids, and difficult to lipread.
