Welcome to the EMO Community Forums, @DSim1 . . . sometimes EMO has trouble understanding high or too low pitched voices or if you have an accent (by that I mean non-American).
You might try to slow down how quickly you speak which goes a long way along with enunciation. You may also wish to submit your voice which will help him to better understand you here.
I have also heard that there is an app called DeepL that you can find in the meantime which is a text to speech which will probably speak to him in a way that he understands better.
My best to you that EMO and you can learn how to best communicate.
