Reword

How would you reword this sentence to make it sound more natural?

When an English speaker realises that a foreign person they are speaking to doesn't understand one of their sentences, they repeat it, the same way, but louder, as though the person were deaf. At no point does it come to their mind that their vocabulary might be complicated or that their expression might most probably be ambiguous to a foreigner and that they could reword it in a simpler way. The result is that not only does the person still not understand, but they get irritated at being considered deaf.

Could you reword that sentence? It sounds a bit forced like this.

I should reword that.
