The long-term goal of this project is to examine the influence of probabilistic phonotactics on lexical retrieval during speech production. Recent work has demonstrated that probabilistic phonotactics affects spoken word recognition; however, little research has been conducted on its affects on speech production. Other findings, examining the effects on speech production of phonologically similar neighborhoods - a factor that is highly correlated with phonotactic probability - suggest that phonotactic information may also influence the speed and accuracy of lexical retrieval in speech production. A number of behavioral tasks, including several newly developed methodologies, as well as more conventional methods, will be used to provide converging evidence of the influence of probabilistic phonotactics on lexical retrieval of words and pseudo-words during speech production. The results of these studies using real words and specially constructed non-words will provide important new insights about the representations and general processing principles operating in speech production and perception. A better understanding of normal lexical retrieval could lead to valuable insights about the processes and representations used during lexical retrieval for speech production by clinical populations, including the elderly; hearing-impaired; and patients with aphasias or other neurogenic disorders.

本项目的长期目标是研究 概率语音学在言语产生过程中词汇提取的应用。 最近的研究表明，概率语音影响口语单词 然而，很少有研究表明， 言语产生 其他研究结果，检查对言语产生的影响 语音相似的社区-一个高度相关的因素 与声定向概率-表明声定向信息也可能 影响了言语产生中词汇检索的速度和准确性。 一 一些行为任务，包括一些新开发的方法， 以及更传统的方法，将被用来提供收敛的证据 概率语音学对词汇提取的影响， 在言语产生过程中的伪词。 这些研究的结果使用真实的 单词和特别构造的非单词将提供重要的新见解 关于言语中的表征和一般处理原则 生产和感知。 对常规词汇检索的再认识 可能会导致对所使用的过程和表示的有价值的见解 在临床人群的语音产生的词汇检索期间， 包括老年人;听力受损;和失语症或其他 神经源性疾病
