Maybe something that uses AI well, etc.?
There are some that use Open AI Whisper but none as deeply integrated as Apples own.
Which ones use whisper?
Are you using Sonoma, or an earlier os? The Sanoma dictation is 10x better than anything that came before it, and better than any other alternatives I’ve tried (dragon products). Make sure you have the right language chosen in the settings, and give it some time to get used to you.
It’s for an iPhone 
Oh, it’s the same scenario - latest os release, right language setting, good microphone, and give it a little time to get used to you.
