| Résumé : | Speech perception is a multisensory process. In cocktail party scenarios, when one is trying to follow a single speaker among multiple concurrent ones, humans can exploit visual input (lip movements) towards improved speech comprehension. Previous studies have shown that somatosensory stimuli can also provide an aiding role in speech-in-noise (SiN) perception. However, studies investigating the potential of tactile stimulation to improve SiN comprehension at the cocktail party remain scarce. Thus, the current study aims to investigate whether the vibratory presentation of the low-frequency, amplitude modulations (temporal envelope) of the speech signal can improve SiN recognition in a multitalker background. The speech envelope has previously been shown to be essential for speech comprehension in adverse listening conditions. To this end, we have developed an ongoing study where participants receive palm tactile stimulation through a vibratory system while listening to sentences from the French Intelligibility Sentence Test (FIST) embedded in a multitalker background noise. The participants’ comprehension is evaluated through their ability to reproduce the sentences. Preliminary results indicate a significant effect of bimanual stimulation on SiN comprehension compared to purely auditory (stimulation-free), or unimanual stimulation conditions. Our results provide preliminary evidence for the potential of tactile, vibratory-type presentation of speech envelope-derived information to benefit SiN perception in cocktail party auditory scenes. |
