Siri does not recognize my name?

I don't own an iPhone, but the majority of my family does. When they go to text me, they say "Hey Siri, text name (message)". Unfortunately I tend to go by the shorter version of my name, one that is also a noun and/or a verb. To combat this, my mother has changed my contact to "My Son name" and that actually does work, but not consistently. Is there any way to make Siri recognize my name as a name, and not as a verb or noun? Note that this was working completely fine until around March or April this year, and works as expected on any other virtual assistant we've tried (Google, Alexa, etc.)
