English tutor Alice here to help you with short vowel sounds! I found this photo online and I find it helpful to those that want to improve their English pronunciation. Record an audio of yourself saying either the words from column A, E, i, O or U. (Column means the words straight down.) I will judge your audio and let you know how you sounded.
(I am a native English speaker born and raised in Ohio.) Good luck! Do not use any audio translation prior to trying this. I want to hear how you sound just based on how you think you should say the words.
