Abstract : Four models were used to predict audio-visual (AV) performance from performances on A and V observed independently. The model assumed that the eye and ear behave as independent 'observers', that the sensors present both a discrete decision and a measure of confidence to the decision system, that the certainty is proportional to the probability of the discrete decision and that an optimal weighting of certainties occurs in cases of conflict between A and V. Reasons for divergencies between bi-modal word recognition and detection studies are discussed. (Author)
