speech to text on iOS continually makes same mistake

As a person who uses speech to text very often, I need a reliable method of conversion. While I know this technology is not perfect, but I keep running into the same error and wonder if there is something I can do. Here is the problem: I have a friend named Kasey, and when I refer to this person while using dictation, the speech to text engine will output K.C.99% of the time In an attempt to remedy this, I went to Settings/General/Keyboard/Text Replacement and inputted the following rules: - KC Kasey - K.C Kasey - K.C. Kasey What's interesting is that if I say Kasey at the start of the sentence the speech to text output will be correct. I found a possible solution that worked for someone else HERE , but I can't navigate to those settings with the version of iOS that I have My presumption here is that text replacement only works while typing, and does not affect text that is generated from speech. If this is the case, how can I remedy my problem? Using iOS 15.7.5 on Iphone7
