项目摘要

DESCRIPTION (provided by applicant): Abnormalities in tongue strength, range of motion, and coordination are primary contributors to speech deficits resulting from stroke, head injury, neuromuscular disease, oral cancer, and developmental delays. Despite the fact that tongue contact with the hard palate is a critical event for normal speech production, data regarding the strength of that contact during speech are limited. The goals of this project are to refine procedures for measuring linguapalatal contact pressure (LPCP) during speech and to gather LPCP data from individuals with unimpaired speech. Specific aims (SA) of the project are to: 1) determine a suitable transducer for measuring LPCP during speech, 2) identify the method of transducer adhesion in the mouth that interferes least with speech, 3) determine the accommodation period speakers require to adjust to the measuring device in the mouth, 4) describe LPCP variation as a function of various speaker behaviors, and 5) evaluate the relationship between LPCP, oral air pressure (P) and linguanalatal contact area (LPCA). Once the methodological issues are resolved, future work involving LPCP measurement will: 1) lead to a more complete understanding of speech production, 2) allow normative data collection to serve as a referent for individuals with disordered speech, and 3) lead to the development of a useful research and clinical procedure to improve the diagnosis and treatment of individuals with speech impairments. SA1 will be achieved by evaluating the response characteristics of two subminiature pressure transducers that appear suitable for LPCP measurement (Experiment 1). This will include transducer performance during speech production. To accomplish SA2, two methods of placing the transducer in the mouth (tape adhesion versus palatal mold mounting) will be compared in Experiment 2. The degree of speech distortion that each method induces will be gauged by evaluating listener perceptions, speaker perceptions, and acoustic features of the productions. SA3 will be met in Experiment 2 by recording speakers at set time intervals with the transducer in place and evaluating changes in listener perception of the speech across the time intervals. SA4 will be addressed in Experiment 3 when LPCP magnitude and variability will be described for a set of consonants spoken by individuals who will systematically vary speech rate, loudness, and articulatory precision. These production parameters are often manipulated therapeutically for individuals with speech deficits. SA5 will be achieved by evaluating the relationships between LPCP, P/o, and LPCA measures simultaneously recorded from individuals with unimpaired speech. Clearer understanding of the relationship between these measures will allow a more complete understanding of speech production, and lead to a larger research application dealing with speech dynamics.

描述（申请人提供）：舌头强度的异常，范围运动和协调是导致语音缺陷的主要因素从中风，头部损伤，神经肌肉疾病，口腔癌和发育延迟。尽管舌头接触与硬pa是至关重要的正常语音生产的事件，有关该联系强度的数据在讲话期间有限。该项目的目标是完善程序在语音期间测量语言拉客接触压力（LPCP）并收集 LPCP来自未经言语障碍的人的LPCP数据。特定目标（SA）项目为：1）确定适合测量LPCP的合适传感器语音，2）确定口腔中传感器粘附的方法最少干扰语音，3）确定住宿时期扬声器需要调整口腔中的测量设备，4）描述LPCP 变异是各种说话者行为的函数，5）评估 LPCP，口服气压（P）与林纳拉塔尔接触区域之间的关系（LPCA）。解决方法论问题后，未来的工作涉及LPCP 测量将：1）对语音产生有更全面的了解， 2）允许规范性数据收集作为具有言语无序，3）导致一项有用的研究的发展和改善个人的诊断和治疗的临床程序语音障碍。 SA1将通过评估响应来实现看起来合适的两个下层压力传感器的特征用于LPCP测量（实验1）。这将包括传感器性能在语音生产中。为了完成SA2，将两种放置的方法嘴里的传感器（胶带粘附与palatal霉菌安装）将是在实验2中进行了比较。语音失真程度是每种方法通过评估听众的看法，说话者的看法，和制作的声学特征。 SA3将在实验2中通过以固定的时间间隔录制扬声器，并与换能器一起录制扬声器评估听众对演讲的看法的变化间隔。当LPCP幅度和对于个人说的一组辅音的人将描述可变性将有系统地改变语音率，响度和发音精度。这些生产参数通常是治疗的患有言语缺陷的人。 SA5将通过评估 LPCP，P/O和LPCA之间的关系同时记录没有言语不足的人。对关系的清晰了解在这些措施之间将使对语音有更全面的了解生产，并导致更大的研究应用程序处理语音动力学。
