本研究调查了词汇频率（已知会影响说出言语反应所需时间的变量）是否也可能影响发音。在图片命名和朗读任务中使用相对频率不同但在词头、元音和音素数量上匹配的单词对（例如，map 与 mat，前者比后者更频繁）。在这两项任务中，低频项目的响应延迟都比高频项目慢，与大声朗读相比，图片命名中的频率效应明显更大。此外，低频项目的初始音素持续时间比高频项目更长。频率对初始音素持续时间的影响在图片命名中比朗读中稍显突出，但其大小非常小，因此我们无法得出词汇频率对发音有影响的结论。此外，与图片命名相比，朗读时首音素和整个单词的持续时间明显更长。我们在当前的朗读和语音产生理论的背景下讨论我们的发现，以及它们所采用的与认知和发音处理水平之间的信息流本质（分级与级联）相关的方法。
The present study investigated whether lexical frequency, a variable that is known to affect the time taken to utter a verbal response, may also influence articulation. Pairs of words that differed in terms of their relative frequency, but were matched on their onset, vowel, and number of phonemes (e.g., map vs. mat, where the former is more frequent than the latter) were used in a picture naming and a reading aloud task. Low-frequency items yielded slower response latencies than high-frequency items in both tasks, with the frequency effect being significantly larger in picture naming compared to reading aloud. Also, initial-phoneme durations were longer for low-frequency items than for high-frequency items. The frequency effect on initial-phoneme durations was slightly more prominent in picture naming than in reading aloud, yet its size was very small, thus preventing us from concluding that lexical frequency exerts an influence on articulation. Additionally, initial-phoneme and whole-word durations were significantly longer in reading aloud compared to picture naming. We discuss our findings in the context of current theories of reading aloud and speech production, and the approaches they adopt in relation to the nature of information flow (staged vs. cascaded) between cognitive and articulatory levels of processing.
