The technique of electropalatography (EPG) records the location and timing of tongue contacts with the hard palate during continuous speech. Recent developments in hardware and software design of the Reading electropalatograph are described and applications of the technique in assessment and remediation of a variety of speech disorders are outlined. In assessment, it is shown that EPG can provide insights into possible origins of auditorily perceived errors, and case descriptions illustrate how this information can lead to a more rationalised approach to treatment. In therapy, the provision of real-time visual feedback of tongue movement can be effective in the remediation of certain types of intractable speech problems. Finally, the importance of techniques such as EPG in the objective evaluation of treatment procedures is discussed in the light of the increasing demand for accountability within the speech therapy service.
电子腭位描记术（EPG）可记录连续言语过程中舌头与硬腭接触的位置和时间。本文介绍了雷丁电子腭位描记仪在硬件和软件设计方面的最新进展，并概述了该技术在各种言语障碍评估和矫治中的应用。在评估方面，研究表明EPG能够深入了解听觉感知错误的可能根源，案例描述说明了这些信息如何能为治疗带来更合理的方法。在治疗方面，提供舌头运动的实时视觉反馈对矫治某些类型的顽固性言语问题可能有效。最后，鉴于言语治疗服务中对问责制的需求不断增加，讨论了诸如EPG等技术在客观评估治疗程序中的重要性。
