press the arrows on your screen to change to previous or next costumes (well letters I guess) also the reason why it's called "Sy∑bols… I.P.A alphabet, v1.1 W.I.P edition" is because; when I was working on Sy∑bols… I.P.A alphabet, v1.1 I was trying to save the update so I downloaded the project and saved it in another project, so I put the other project in the trash, and currently this is the project that was in the trash.
also the reason that there are mistakes is that I forgot to fix some of the names. thanks to the I.P.A (A.K.A International Phonetic Alphabet) if you want to see where I got these letters go visit: https://www.internationalphoneticalphabet.org/ipa-sounds/ipa-chart-with-sounds/
