To investigate the interaction between the auditory and oral sensory feedback modalities during speech production lingual vibrotactile thresholds were obtained from subjects in the following conditions: (1) before and after speech production with normal auditory feedback, (2) before and after speech production under exposure to auditory masking, and (3) before and after exposure to auditory masking without performing speech tasks. In addition duration measurements were obtained for selected speech sounds to investigate temporal changes in the articulatory patterns of subjects in the various conditions. Lingual sensory decreases and temporal reorganization were observed only in subjects speaking under auditory masking. These data suggest a balanced interaction between auditory and oral sensory feedback modalities which, when disturbed, results in non-phonemic change in speech production.
为了研究言语产生过程中听觉和口腔感觉反馈模式之间的相互作用，在以下条件下从受试者获取舌部振动触觉阈值：(1) 正常听觉反馈下言语产生前后；(2) 在听觉掩蔽情况下言语产生前后；(3) 不执行言语任务时暴露于听觉掩蔽前后。此外，还获取了选定语音的时长测量值，以研究不同条件下受试者发音模式的时间变化。仅在听觉掩蔽下说话的受试者中观察到舌部感觉下降和时间重组。这些数据表明听觉和口腔感觉反馈模式之间存在平衡的相互作用，当这种相互作用受到干扰时，会导致言语产生中的非音素变化。
