 The study found that presenting a vibratactile signal derived from the speech temporal envelope can improve speech and noise, SYN, intelligibility in a multi-talker background for untrained, normal hearing listeners. Vibratactile sensitivity, evaluated using vibratactile detection thresholds, modulates the extent of audio-tactile SYN improvement. The study also found that concurrent vibratactile stimulation delivered to the left or right palm all both led to a significant improvement in SYN recognition when compared to the audio-only condition. The results highlight the potential of concurrent vibratactile stimulation to improve SYN recognition, especially in individuals with poor SYN perception abilities, and tentatively more so with increasing tactile sensitivity.
