Shosaiyomi is a set of expressions used to explain Kanji characters to blind PC users phonetically. The purposes of our research are to analyze the factors which affect the comprehensibility of shosaiyomi, develop a new set of shosaiyomi based on the analysis and evaluate it.1. We analyzed the word familiarity and components of shosaiyomi of screen reader products and found that as the degrees of difficulty increase, (1) the word familiarity lowers, and (2) the numbers of components and their combinations increase.2. We performed a survey on familiarity of elementary school children with words that were selected from "Educational Fundamental Vocabulary" and found that the average of word familiarity significantly changes in accordance with the grade in which the words first appear in the textbooks.3. We have conducted a Kanji writing test with adults as subjects. Their average correct rate was higher than that of elementary school children by 30%. It shows that the lower performance by … More school children stemmed from their relatively smaller vocabulary.4. Taking vocabulary and word familiarity characteristics of school children into account, we developed a new set of shosaiyomi for 1006 Educational Kanji characters. To evaluate it, a Kanji writing test with school children as subjects was conducted. The result was that the average correct rate in this test was higher than that in the test with shosaiyomi of conventional screen reader products.5. Taking vocabulary and word familiarity characteristics of the users into consideration, we developed a new set of shosaiyomi for 2965 JIS 1 level Kanji characters. To evaluate it, we conducted a Kanji writing test with university students as subjects. As a result, a set of shosaiyomi comprising words with higher familiarity gained a significantly higher average correct rate than another set comprising of words with lower familiarity.6. We proposed a new strategy of explaining the meaning of paired Kanji characters by the unit of word. Prototype program with this function gained favorable comments from the test users. Less

Shosaiyomi是一组用于向盲人PC用户解释汉字字符的语音表达。本研究的目的是分析影响小资约言理解性的因素，在此基础上开发一套新的小资约言，并对其进行评价.通过对屏幕阅读器产品的词汇熟悉度和词汇组成成分的分析，发现随着难度的增加，（1）词汇熟悉度降低，（2）词汇组成成分及其组合的数量增加.本研究以《教育基础词汇》中的词汇为研究对象，对小学儿童的词汇熟悉程度进行了调查，发现词汇熟悉程度的平均值随着词汇首次出现在教科书中的年级而显著变化.我们以成年人为对象进行了汉字写作测试。他们的平均正确率比小学生高出30%。它表明， ...更多信息 学龄儿童由于他们的词汇量相对较小.考虑到学龄儿童的词汇量和词汇熟悉度的特点，我们开发了一套新的1006个教育用汉字的小斋约米。为了评估它，一个汉字写作测试与学生作为主题进行。结果是，在这个测试中的平均正确率高于在测试中使用传统屏幕阅读器产品的shosaiyomi.考虑到用户的词汇和单词熟悉度的特点，我们开发了一套新的shosaiyomi为2965 JIS 1级汉字。为了评估这一点，我们进行了汉字写作测试的大学生为对象。结果表明，由熟悉度较高的单词组成的一组字母与单词的平均正确率显著高于由熟悉度较低的单词组成的另一组字母与单词的平均正确率。提出了以词为单位解释成对汉字意义的新策略。具有该功能的原型程序得到了测试用户的好评。少
