The brain can restore missing speech segments using linguistic knowledge and context. The phonemic restoration effect is commonly quantified by the increase in intelligibility of interrupted speech when the silent gaps are filled with noise bursts. In normal hearing, the restoration effect is negatively correlated with the baseline scores with interrupted speech; listeners with poorer baseline show more benefit from restoration. Reanalyzing data from Başkent et al. [(2010). Hear. Res. 260, 54-62], correlations with mild and moderate hearing impairment were observed to differ than with normal hearing. This analysis further shows that hearing impairment may affect top-down restoration of speech.
大脑可以利用语言知识和上下文来恢复缺失的言语片段。语音恢复效果通常通过在静音间隙中填充噪声突发时中断言语的可懂度增加来量化。在正常听力中,恢复效果与中断言语的基线分数呈负相关;基线得分较差的听众从恢复中获益更多。对 Başkent 等人的数据进行重新分析[(2010)。听觉研究 260, 54-62],发现与轻度和中度听力障碍的相关性与正常听力不同。这项分析进一步表明,听力障碍可能会影响言语的自上而下的恢复。
