【摘要】 数学公式具有含义丰富的二维结构,造成数学公式读音的歧义性。针对数学公式读音歧义性问题,提出利用读音顺序变换和引入修饰符的读法规则,改进并补充原有Math AL规则。首先,通过数学公式日常读法规律进行研究,提出读音歧义性的原因并作出解释;其次,实验发现运算符读音顺序改变可以消除部分读音歧义;最后,引入修饰符的方案解决剩余读音的歧义性。Math AL规则与Math Player规则相比,公式读音歧义率均为15%左右,相同数量的公式读音的字符数减少30%,读音时间减少1.73 min。实验结果表明,Math AL规则更加简洁、高效,且符合用户习惯。更多还原

【Abstract】 For mathematical formula,the diversity of two-dimensional structure causes the pronunciation ambiguity.Focusing on the issue that mathematical formula pronunciation ambiguity problem,using pronunciation sequence transformation and introducing modifiers were proposed to improve the pronunciation rules of Math AL.Firstly,through the study of mathematical formula daily reading rules,the cause of pronunciation ambiguity was presented and explained.Secondly,it was found that the operator sequence of pronunciation could liminate partial pronunciation ambiguity in the experiment.Finally,the modifier rule was introduced to solve the remained problem.Compared with Math Player,the formula pronunciation ambiguity rate of Math AL is also about 15%,but the number of characters is reduced by 30% and pronunciation time is reduced by 1.73 minutes under the same amount of formulas.The experimental results show that the Math AL rule is simple,efficient,and it conforms to user habits.更多还原
