对 4 项针对英语单音节口语阅读的大规模研究的语音响应时间 (RT) 测量结果进行了分析，以证明语音键测量值因响应的主要音素而产生偏差。具有不同初始音素的单词确实具有显着不同的 RT。在排除了频率、长度和拼写一致性等九个协变量的贡献以及排除了与错误率相关的方差后，这种效应仍然存在。按音素细分显示，清辅音、后辅音和晦涩辅音的检测时间晚于其他辅音。单词的第二个音素也对 RT 产生影响：具有高元音或前元音的单词稍后被检测到。由于语音键导致的基于音素的偏差很大（范围约为 100 毫秒）且普遍存在，足以引起对语音 RT 测量结果解释的担忧。讨论了最小化这些偏差影响的技术。 (C) 2002 年爱思唯尔科学（美国）。
Voice response time (RT) measurements from 4 large-scale studies of oral reading of English monosyllables were analyzed for evidence that voice key measurements are biased by the leading phonemes of the response. Words with different initial phonemes did have significantly different RTs. This effect persisted after contributions of nine covariables, such as frequency, length, and spelling consistency, were factored out, as well as when variance associated with error rate was factored out. A breakdown by phoneme showed that voiceless, posterior, and obstruent consonants were detected later than others. The second phonemes of the words also had an effect on RT: Words with high or front vowels were detected later. Phoneme-based biases due to voice keys were large (range about 100 ms) and pervasive enough to cause concern in interpreting voice RT measurements. Techniques are discussed for minimizing the impact of these biases. (C) 2002 Elsevier Science (USA).
