Outline of Final Research Achievements |
It is challenging for non-native listeners to accurately perceive foreign sounds in noisy and reverberant listening environments, regardless of their language proficiency. Several identification experiments were carried out to examine how language proficiency and noise/reverberation levels affect perception in adverse environments. In addition, a training experiment was carried out to examine whether training English fricatives and approximants in noise would improve accuracy. Comparison of data before and after training sessions showed that identification rates improved from 65% to 91% on average in all participants.
