本文描述了一种新的扫描通信自动纠错方法，其原理基本类似于连续语音识别。它有两个核心组件：一个是开关时序模型，另一个是统计语言模型。通过使用这些模型，所提出的系统可以在考虑用户特征的情况下，针对给定的切换定时序列估计最可能的输入音节序列。13名非残疾受试者和一名肌萎缩侧索硬化症受试者参加了使用所提出的扫描通信系统的文本输入实验。对于肌萎缩侧索硬化症患者，该系统将字符正确率从77.7%提高到97.7%，从而实现了极快的输入。
This paper describes a novel automatic error correction method for scanning communication, whose mechanism is basically analogous to that of continuous speech recognition. It has two core components: one is the switch timing model, and the other is the statistical language model. By employing these models, the proposed system can estimate most probable sequence of input syllables for a given sequence of switch timing, with taking user characteristics into account. Thirteen subjects without disabilities and an ALS subject participated in a text input experiment using the proposed scanning communication system. For the ALS subject, the system improved the character correct rate from 77.7% to 97.7%, allowing dramatically fast input.
