Unifon is a special way of writing words that some people use. Instead of using the regular letters we know, like A, B, and C, Unifon uses special shapes and lines to represent sounds.
So, for example, instead of writing "cat" with the letters C, A, and T, Unifon would use different shapes to represent the sounds "cuh," "ahh," and "tuh."
Using Unifon can help people who have trouble hearing or speaking some words. They can look at the special Unifon shapes and know what sounds the words are supposed to make.
Overall, Unifon is just a different way to write words, using special shapes to represent sounds instead of letters.
