The effects of two types of auditory distracters (steady-state noise vs. four-talker babble) on visual-only speechreading accuracy were tested against a baseline (silence) in 23 participants with above-average speechreading ability. Their task was to speechread high frequency Swedish words. They were asked to rate their own performance and effort, and report how distracting each type of auditory distracter was. Only four-talker babble impeded speechreading accuracy. This suggests competition for phonological processing, since the four-talker babble demands phonological processing, which is also required for the speechreading task. Better accuracy was associated with lower self-rated effort in silence; no other correlations were found.
两种类型的听觉干扰（稳态噪声与四声道语音混响）对 23 名具有较高言语阅读能力的参与者的视觉言语阅读准确性的影响与基线（静音）进行了测试。他们的任务是阅读高频瑞典语单词。要求他们对自己的表现和努力进行评分，并报告每种类型的听觉干扰有多么分散注意力。只有四声道语音混响会干扰言语阅读的准确性。这表明存在语音处理方面的竞争，因为四声道语音混响需要语音处理，而这也是言语阅读任务所必需的。在静音状态下，自我评估的努力程度越低，准确性越高；未发现其他相关性。
