    The evolution continues: the clinical trials of the SPEAK strategy in Nucleus 22 channel cochlear implant users [Abstract]
    Antognelli, Trisha ; Whitford, Lesley ; SELIGMAN, PETER ; Everingham, Colleen ; Skok, Marisa ; Plant, Kerrie ; Hollow, Rod ; Staller, Steve ( 1994)
    Research in the field of cochlear implants continues in centres around the world. The aim of all centres is to improve the speech perception abilities of those children and adults fitted with a cochlear implant. Most recently the work of Hugh McDermott and Colette McKay (Melbourne University, Department of Otolaryngology) in developing and researching the SMSP (Spectral Maxima Sound Processor) has greatly enhanced the speech understanding abilities of a number of subjects implanted with the Nucleus 22 Channel Cochlear Implant.

    Clinical trial of a multiple-channel cochlear prosthesis: an initial study in four patients with profound total hearing loss
    Bailey, Quentin R. ; Seligman, Peter M. ; Tong, Yit. C. ; Clark, Graeme M. ; Dowell, R. C. ; Brown, Alison M. ; Luscombe, Susan M. ; Pyman, Brian C. ; Webb, Robert L. ( 1983)
    The clinical trial of a multiple-channel cochlear prosthesis was undertaken in four patients with postlingual deafness and profound total hearing loss. The results of open-set speech tests confirmed that, using electrical stimulation alone, one patient could have a meaningful conversation with resorting to lipreading (for example, this patient uses the prosthesis to converse with her husband on the telephone). The results of closed-set speech tests also suggested that a multiple-channel stimulator is more effective than a single-channel one in conveying speech information. The cochlear prosthesis was especially effective in all four patients when it was used in conjunction with lipreading, and speech-tracking tests showed that the patients could combine the information obtained from both electrical stimulation and lipreading.

    A multiple-channel cochlear implant and wearable speech-processor: an audiological evaluation
    Tong, Y. C. ; Clark, Graeme M. ; Dowell, R. C. ; Martin, L. F. ; Seligman, P. M. ; Patrick, J. F. ( 1981)
    Standard audiological tests were administered to a totally deft multiple-channel cochlear implant patient with a wearable speech-processor in a monitored sound field under the following conditions: a wearable unit activated alone (WA), lipreading with the wearable unit off (LA), and wearable unit activated in combination with lipreading (WL). Thresholds obtained for narrow-band noise signals indicated that the wearable unit allowed the patient to detect a variety of sounds at different frequencies. The results obtained in closed-set word tests and open-set word and sentence tests showed significant improvements in word and sentence scores from LA to WL. In the open-se (C.I.D) sentence tests, the patient scored 22% for LA and 76% for WL. The WL score of 76% correlates with a satisfactory performance in understanding connected speech. The patient also scored 30% correct in a test involving the recognition of environmental sounds.
