We investigated whether orthographic information influences speech production. We used a non-color-word version of the Stroop task in which participants had to ignore the presented words but name their ink color instead. In two experiments, we manipulated the phonological and orthographic relationships between the words and their ink color and the tasks’ context by preactivating or not orthographic information. The relation between the first letter of the prime word and the first phoneme of the color name was phonological or orthographic and phonological or unrelated. In Experiment 1, only phonological information carried out by the prime word affected spoken naming; orthographic information did not help. In Experiment 2, speech production was influenced by orthographic information only after an initial writing task. This confirms that orthographic information can support speaking and that speech is sensitive to properties of the task’s context, suggesting that orthographic information is coactivated online with phonological information.

演讲前写作会改变演讲的产生。

我们调查了正字信息是否影响语音产生。我们使用了Stroop任务的非彩色单词版本，其中参与者必须忽略出现的单词，而改用其墨水颜色。在两个实验中，我们通过预先激活或不激活拼字信息来操纵单词及其墨水颜色与任务上下文之间的语音和拼字关系。素词的第一个字母与颜色名称的第一个音素之间的关系是语音的或正字的，语音的或无关的。在实验1中，只有素词执行的语音信息会影响口语命名；正字法信息无济于事。在实验2中，语音生成仅在完成初始写作任务后受拼字信息影响。
