腭电图（EPG）技术提供了连续语音过程中舌与硬腭接触的详细时空信息。在该技术的大多数可用版本中，接触数据以100-200 Hz的采样率从安装在人造腭表面上的多个电极（通常超过60个）获得。通过适当的计算机处理可以获得详细的定性信息，但对于许多目的，例如统计分析，需要定量数据。本文综述了EPG数据处理的一些新方法，包括接触模式的数值指标。
The technique of electropalatography (EPG) provides detailed spatio-temporal information on tongue contacts with the hard palate during continuous speech. In most available versions of the technique the contact data are obtained at a sampling rate of 100–200 Hz from a number of electrodes (usually more than 60) mounted on the surface of an artificial palate. Detailed qualitative information is available from appropriate computer processing, but for many purposes, e.g. for statistical analysis, quantitative data are required. This paper reviews some recent methods of EPG data reduction including numerical indices of contact patterns.
