Recognition of foreign-accented vocoded speech by native English listeners

This study examined how talker accentedness affects the recognition of noise-vocoded speech by native English listeners and contextual information interplays with during this process. The included 20 English-speaking, normal-hearing adults aged between 19 23 years old. stimuli were Hearing in Noise Test (HINT) Revised Speech Perception (R-SPIN) sentences produced four Mandarin talkers (two males two females) who learned as a second language. Two (one each sex) had mild foreign accent other moderate accent. A six-channel noise vocoder was used to process stimulus sentences. vocoder-processed unprocessed presented listeners. results revealed that talkers’ accents introduced additional detrimental effects besides spectral degradation negative effect exacerbated became stronger. While provided beneficial role recognizing mildly accented vocoded speech, magnitude benefit decreased increased. These findings joint influence variability sentence context on perception degraded speech.
