Previous studies have concluded that breath intake patterns during speech emerge as a function of planning processes. Little work has tested for similar effects of respiratory recovery on these patterns. Moreover, previous work has relied on one-by-one elicitation of read sentences which incorporates a direct cue to upcoming length, allowing for anticipatory effects to emerge but prohibiting a test of preceding material on intakes. The current study investigated the relative influences of recovery and anticipatory factors on breath intakes in a connected speech task that better approximates spontaneous production. Participants (N = 6) were asked to recite a passage of 20 unrelated sentences from memory. Results revealed a significant effect of preceding utterance length on presence of breath intakes during pauses, but not of following utterance length. It is concluded that respiratory recovery drives breath intakes in connected speech.
先前的研究得出结论，言语过程中的吸气模式是计划过程的函数。很少有研究测试呼吸恢复对这些模式的类似影响。此外，先前的研究依赖于逐句引出朗读的句子，其中包含对即将到来的句子长度的直接提示，这使得预期效应得以出现，但禁止测试前一句内容对吸气的影响。本研究在一项更接近自发言语产生的连贯言语任务中，调查了恢复因素和预期因素对呼吸吸气的相对影响。参与者（N = 6）被要求凭记忆背诵一段包含20个不相关句子的文章。结果显示，前一句的长度对停顿期间呼吸吸气的出现有显著影响，但后一句的长度则没有。研究得出结论，在连贯言语中，呼吸恢复驱动呼吸吸气。
