I think there is an app called MyEar which has a one time fee that you could try. I know there are others. Type in text to speech in the search and see what you get. For andriod app there is Google Live transcribe
There is otter.ai app for both Iphones and Andriod so give that a try.
I use Live Transcribe on a phone with the Android OS. I do not know about ones for Iphone's IOS.
As well as one on one conversation I use it regularly for the part of a church service that goes over the regular sound system; but it has problems with comments from the congregation that are not spoken into a mic to go into the sound system unless it is someone sitting next to me. Because I always have a corded mic plugged in the only things I have to do since my Pastor has been conducting services over Facebook Live during the Virus "Stay at home" orders is make sure the mic is beside the computer speaker and the sound on the computer is turned up. Reading it on my phone does not make me miss much because the picture 99.9% of the time is just Pastor's head and upper body.
I found problems when eating out in a group because of not knowing who was going to be speaking to get the mic right up to them.
You do need to be aware of context. Like last Christmas at one point it had Jesus being born in a bar rather than a barn.
