title: A pilot experiment on the effects of an acoustically applied reduced speech signal on speechreading.
abstract: The aim of this study was to investigate how speechreading of short sentences could be enhanced by presenting the acoustic signal with real-time extracted supplementary speech features. The features were second format frequency and voiceless frication. A group of 10 normal-hearing subjects participated in a simulation experiment. Speechreading performance increased from 22.2% for speechreading only (pretraining), to 61.5% for speechreading plus supplementary auditory information (post-training). The gain from the acoustic information turned out to be larger for subjects who also performed better in the speechreading-only condition. No significant effect was found for the training volume (i.e. 30 minutes versus 5 hours).
