Purpose The study was designed primarily to determine if the use of hearing aids (HAs) in individuals with hearing impairment in China would affect their speechreading performance. Method Sixty-seven young adults with hearing impairment with HAs and 78 young adults with hearing impairment without HAs completed newly developed Chinese speechreading tests targeting 3 linguistic levels (i.e., words, phrases, and sentences). Results Groups with HAs were more accurate at speechreading than groups without HA across the 3 linguistic levels. For both groups, speechreading accuracy was higher for phrases than words and sentences, and speechreading speed was slower for sentences than words and phrases. Furthermore, there was a positive correlation between years of HA use and the accuracy of speechreading performance; longer HA use was associated with more accurate speechreading. Conclusions Young HA users in China have enhanced speechreading performance over their peers with hearing impairment who are not HA users. This result argues against the perceptual dependence hypothesis that suggests greater dependence on visual information leads to improvement in visual speech perception.
目的 本研究主要旨在确定在中国，听力受损个体使用助听器（HA）是否会影响其唇读表现。方法 67名佩戴助听器的听力受损青年和78名未佩戴助听器的听力受损青年完成了针对3个语言水平（即单词、短语和句子）新开发的中文唇读测试。结果 在这3个语言水平上，佩戴助听器的组比未佩戴助听器的组唇读更准确。对于两组而言，短语的唇读准确性高于单词和句子，句子的唇读速度慢于单词和短语。此外，使用助听器的年限与唇读表现的准确性呈正相关；使用助听器的时间越长，唇读越准确。结论 在中国，使用助听器的年轻听力受损者比未使用助听器的同龄人唇读表现更好。这一结果与感知依赖假说相悖，该假说认为对视觉信息的更大依赖会导致视觉言语感知能力的提高。
