However, as vibrotactile cues normally accompany acoustic cues, no difference in signal speed – and no concomitant perceptual asymmetry – is experienced between these two modalities. Contrary to previous research, we predict a symmetrical window for integration. A portable voice-coil transducer is used to produce vibrotactile stimuli, similar to the laryngeal vibrations normally felt in voiced speech. Results of an experiment will be presented in which participants are asked to discriminate between minimal pairs in noise with the device between their thumb and index finger, and in which audio and vibrotactile stimuli are presented in different orders and at different temporal offsets. Implications will be discussed for theories of cross-modal integration.
