A 12-consonant confusion study on a multiple-channel cochlear implant patient

A consonant confusion study was undertaken on a multiple-channel cochlear implant patient using a wearable speech processing device. This patient suffered from total bilateral deafness acquired postlingually. The consonants /b/,/p/,/m/,/v/,/f/,/d/,/t/,/n/,/z/,/s/,/g/,/k/ were presented in a VCV context with the vowel /a/ as in father by a male and female speaker under three conditions: lipreading alone; electrical stimulation alone using the wearable speech processor and multiple-channel cochlear implant; lipreading in conjunction with electrical stimulation.
