I don't think you could do any better unless you were from Cupertino. With an Irish accent, my experience has been... okay with Apples text to speech, it's certainly better than others, but I still have to make a conscious effort to enunciate quite differently to my normal speech.

OpenAI's whisper has really impressed me though, and transcribes almost everything perfectly, even if I throw in phrases or words from other languages part way through the conversation.
