我们研究了无脚本句子生成过程中的语音编码，重点研究了语音重叠对语音编码的影响。以前关于这个问题的研究几乎完全采用了孤立的单词生成或高度脚本化的多单词生成。这些研究导致了相互矛盾的结果：一些研究发现两个单词之间的语音重叠促进了语音编码，而另一些研究发现了抑制作用。对于这些范例的一个担忧是，它们涉及的过程并不是日常语言使用的典型过程，这就引发了一个问题，即他们的发现在多大程度上说明了语言生成的架构和机制。我们提出了一个范式来研究句子中单词之间的语音重叠的后果，同时让说话者在日常语言使用中选择很多典型的词汇和结构。以英语为母语的成年人在短视频中描述了这些事件。我们在整个句子的各个点上注释了不流利和语速的存在，以及组成顺序。我们发现语音重叠对语音编码有抑制作用。具体来说，如果相邻的实义词有相同的语音起点（例如，hand the hammer），那么它们之前就有发音困难，这反映在流利度和语速上。我们还发现，这种产生困难会影响说话人在语法编码过程中的构成顺序偏好。我们讨论了我们的结果和以前的工作，以分离导致促进或抑制结果的其他范式的特性。从我们的范式中得到的数据也说明了关于语音规划在无脚本语音中的范围以及语音和语法编码是否相互作用的问题。
We investigate phonological encoding during unscripted sentence production, focusing on the effect of phonological overlap on phonological encoding. Previous work on this question has almost exclusively employed isolated word production or highly scripted multi-word production. These studies have led to conflicting results: some studies found that phonological overlap between two words facilitates phonological encoding, while others found inhibitory effects. One worry with many of these paradigms is that they involve processes that are not typical to everyday language use, which calls into question to what extent their findings speak to the architectures and mechanisms underlying language production. We present a paradigm to investigate the consequences of phonological overlap between words in a sentence while leaving speakers much of the lexical and structural choices typical in everyday language use. Adult native speakers of English described events in short video clips. We annotated the presence of disfluencies and the speech rate at various points throughout the sentence, as well as the constituent order. We find that phonological overlap has an inhibitory effect on phonological encoding. Specifically, if adjacent content words share their phonological onset (e.g., hand the hammer), they are preceded by production difficulty, as reflected in fluency and speech rate. We also find that this production difficulty affects speakers’ constituent order preferences during grammatical encoding. We discuss our results and previous works to isolate the properties of other paradigms that resulted in facilitatory or inhibitory results. The data from our paradigm also speak to questions about the scope of phonological planning in unscripted speech and as to whether phonological and grammatical encoding interact.
