The effect of seeing the interlocutor on auditory and visual speech production in noise

چکیده
Talkers modify their speech production in noisy environments partly as a reflex but also as an intentional communicative strategy to facilitate the transmission of the speech signal to the interlocutor. Previous studies have shown that talkers can adapt both auditory and visual elements of speech produced in noise. The current study examined whether auditory and visual speech production would be affected by being able to see their interlocutor or not. Participants completed an interactive communication game in various quiet and in noise conditions with/without being able to see their interlocutor. The results showed that the amplitude of talkers‟ speech modifications was significantly lower when interlocutors could see each other. Furthermore, talkers instead increased the saliency of their visual speech production (measured as lip-area) in noisy conditions for face-to-face communication. These results suggest that talkers actively monitor their environment and adopt appropriate speech production for efficient communication.

Effect of Vowel Auditory Training on the Speech-In-Noise Perception among Older Adults with Normal Hearing
Introduction: Aging reduces the ability to understand speech in noise. Hearing rehabilitation is one of the ways to help older people communicate effectively. This study aimed to investigate the effect of vowel auditory training on the improvement of speech-in-noise (SIN) perception among elderly listeners. Materials and Methods: This study was conducted on 36 elderly ...
متن کاملEffect of signal to noise ratio on the speech perception ability of older adults
Background: Speech perception ability depends on auditory and extra-auditory elements. The signal-to-noise ratio (SNR) is an extra-auditory element that has an effect on the ability to normally follow speech and maintain a conversation. Speech in noise perception difficulty is a common complaint of the elderly. In this study, the importance of SNR magnitude as an extra-auditory effect on speech...

متن کاملEffects of ageing on speed and temporal resolution of speech stimuli in older adults
Background: According to previous studies, most of the speech recognition disorders in older adults are the results of deficits in audibility and auditory temporal resolution. In this paper, the effect of ageing on timecompressed speech and auditory temporal resolution by word recognition in continuous and interrupted noise was studied. Methods: A time-compressed speech test (TCST) w...
