The effect of audibility on audio-visual speech perception in infant cochlear implant recipients

Very young children were followed during their pre-operative, hearing aid use and subsequent cochlear implant use. Repeated measures of audio-visual (AV) speech perception were collected from each child using the Split-Screen Preferential Looking Paradigm (SPLP). Audibility was calculated using the Speech Intelligibility Index (SII) pre- and post-cochlear implantation. The relationship of AV speech perception to changes in audibility was examined retrospectively using an approximation of a single-subject design. A subset of this preliminary data is presented.
