However, the underlying mechanisms behind the effect of speaker familiarity are not fully understood. In this study, a 24-year-old Mandarin-speaking woman with cerebral palsy and a 26-year-old woman with normal speak patterns produced lists of isolated monosyllables, bisyllabic words and bisyllabic pseudowords. Listeners who were familiar with the dysarthric speaker (the speaker’s parents and brothers) and naive listeners were asked to listen to and transcribe these items. We found no difference between the two groups of listeners with regard to their transcriptions of the normal speech, but we found familiar listeners had substantially higher intelligibility scores than the naive listeners on identifying dysarthric speech produced by the speaker with cerebral palsy. The effect was more pronounced for bisyllabic words than isolated syllables and bisyllabic pseudowords, suggesting that the familiarity effect resulted from the interaction between speech decoding and word knowledge.zh-TW
