Influences of visual speech information on the perception of foreign-accented speech in noise

چکیده
This study examined the extent to which visual speech assisted native Australian English speakers to perceive Japanese-accented English compared with Australian English spoken sentences presented in speech-shaped noise (SNR:-4dB). Twenty-one native Australian English listeners performed a speech perception in noise task with Japaneseaccented and Australian English sentences in two conditions: an Audio-only condition (AO) and an Audio-visual condition (AV) where the talker’s face was also shown. The results showed that the addition of visual speech information facilitated the speech perception for both Australian English and Japaneseaccented English. However, the visual benefit was significantly smaller in the perception of Japaneseaccented English, indicating that foreign-accented speech affects the visual speech benefit potentially due to non-native visual form and timing differences.

Influences of Cognitive Processing Capacities on Speech Perception in Young Adults
Foreign accent in speech often presents listeners with challenging listening conditions. Consequently, listeners may need to draw on additional cognitive resources in order to perceive and comprehend such speech. Previous research has shown that, for older adults, executive functions predicted perception of speech material spoken in a novel, artificially created (and therefore unfamiliar) accen...
متن کاملPerceiving foreign-accented auditory-visual speech in noise: the influence of visual form and timing information
The present study examined the extent to which visual form and timing information assisted in the perception of native English and Japanese-accented English speech in noise. We also examined whether the degree of visual facilitation would be mediated by the talkers’ English experience. Thirty native Australian English listeners performed a speech perception in noise task with English sentences ...
متن کاملThe Role of Spectral Resolution in Foreign-Accented Speech Perception
Several studies have shown that diminished spectral resolution leads to poorer speech recognition in adverse listening conditions such as competing background noise or in cochlear implants. Although intelligibility is also reduced when the talker has a foreign accent, it is unknown how limited spectral resolution interacts with foreign-accent perception. It is hypothesized that limited spectral...
متن کاملReliability of Interaural Time Difference-Based Localization Training in Elderly Individuals with Speech-in-Noise Perception Disorder
Background: Previous studies have shown that interaural-time-difference (ITD) training can improve localization ability. Surprisingly little is, however, known about localization training vis-à-vis speech perception in noise based on interaural time difference in the envelope (ITD ENV). We sought to investigate the reliability of an ITD ENV-based training program in speech-in-noise perception a...
متن کاملThe neural processing of foreign-accented speech and its relationship to listener bias
Foreign-accented speech often presents a challenging listening condition. In addition to deviations from the target speech norms related to the inexperience of the nonnative speaker, listener characteristics may play a role in determining intelligibility levels. We have previously shown that an implicit visual bias for associating East Asian faces and foreignness predicts the listeners' percept...
