That experience likely isn’t transferable to Siri, that has deeper problems. People, me included, are reporting their problems with Siri, e.g. setting it to transcribing what they and Siri says as text on the screen, and then are able to show that given input as “Please add milk to the shopping list” results in Siri responding “I do not understand what speaker you refer to.”, in writing.

Likely problems like these could be overcome, but preparing better input would probably not address the root cause of the problems with Siri.
