默声音符编码文本输入方法

人们希望语音输入能够取代键盘, 成为计算机文本输入的最主要方式. 但语音输入在噪声环境中准确率低, 且会泄露输入信息, 也会影响他人. 本文提出默声音符编码文本输入方法, 该方法选择默声音中容易发声、容易精准识别且彼此间容易区分的少数几个音素作为默声音符(silent voice symbol), 对各种字符进行编码. 类似摩尔斯电码, 用户只需要记住编码方式, 就可以通过读默声音符准确地实现文本输入. 实验证明提出的方法有潜力替代键盘在各种环境下完成文本输入任务.

A text input method based on silent voice symbol encoding

Speech input is expected to become the principal method of computer text input and replace the keyboard. But speech input is seriously degraded in nosiy environment, and often makes a leakage of information as well. To avoid these problems, this paper presents a text input method based on silent voice symbol encoding. We select several easy-to-pronounced and easy-to-recognized phonemes in silent voice as silent voice symbols (SVSs) to encode characters. Similar to Morse code, memorizing the encoding scheme, users can input text accurately by speaking relevant SVSs. Experimental results demonstrate that the proposed method is promising to be a reliable method of text input for many applications.
