我一直在 Matlab 中进行字素到音素的转换，并尝试生成一个更通用的代码，以首先将单词分解为特定的辅音、二合字母及其相关元音，并将每个输入的字符串（单词）分割成它的字素形式，以便它可以在以后产生适当的语音合成。然而，由于存在大量规则，因此存在大量 if-elseif-else，循环遍历每个字母并存在不断增长的数组，时间复杂度增加了很多，并且没有给出任何结果（它显示繁忙，每次我通过控制台输入字符串时）。所以如果你能帮我简化代码，下面是：

prompt='Enter a string: ';
str=input(prompt,'s');
l=length(str);
grapheme=[];
i=1;

while (i<=l)

        if strcmpi(str(i),'b')  
            grapheme=[grapheme;{'b'}];
        elseif strcmpi(str(i:i+1),'bb')
            grapheme=[grapheme;{'b'}];
            i=i+1;
        elseif strcmpi(str(i),'d') 
            grapheme=[grapheme;{'d'}];
        elseif strcmpi(str(i:i+1),'dd')||strcmpi(str(i:i+1),'ed')
            grapheme=[grapheme;{'d'}];
