Here is a question that you've not answered: Does the change you are proposing fix a typo that could potentially cause confusion down the road?
You've mentioned that you point out "typos to do with internal acronyms and terms". And in some cases I can see the importance of correcting a typo. If there are two internal acronyms, ABC and ACB, and someone in the meeting uses the wrong one then potentially(if there is no context perhaps) this could lead to confusion. But honestly?
This part of my answer will be split into two parts. The first involves meeting notes that are meant to be post processed and distributed or involving communication outside your team and work. The second involves internal, 'meeting minutes'.
Let's go with the first. If a group in a meeting is working together on a document that will be released externally, then everyone in the room should be on point in catching and alleviating typos and poor communication. These materials are unique because, ultimately, they will represent the organization to the outside world. There is a responsibility, in this case, to speak up about any ambiguity or mistakes. In this case you, and everyone else in the room, is absolutely in the right to correct, gently if possible, any mistakes.
The second? Well the second situation is where you kind of come off looking like a jerk. Internal, informal meeting minutes for casual meetings are just that: informal, internal and casual. Things that do not accurately represent the meeting should be called out. Say if the meeting agreed to do XYZ and the meeting minutes say "By consensus the group has agreed NOT to do XYZ" Otherwise? You're showing off whether you realize it or not. Whether it is your intention or not you are attempting to show how much more you know/notice/etc than the person taking the notes. If it bothers you that much? Take the notes yourself.
Is anyone else in the room suggesting fixes for typos? Really think back over the last few meetings - how many times has everyone in the room spoken up? Of that, for each person, roughly what percentage was to correct typos in the meeting minutes? This is how you can gauge how your regular 'corrections' are being taken. There is an important lesson all developers and IT have to learn eventually and that is the lesson of 'Good enough'. You are, absolutely, putting your working relationship with other people in the room at risk every time you recommend a 'correction' and for what gain? Do these notes live on forever, being referenced back constantly? Or are they like most meeting minutes where they get dumped on a network drive, emailed out or on a sharepoint in order to show that, yes, things happened in the meeting? What is the real benefit, other than scratching your typo itch, that these corrections provide?
Imagine, for a moment, if you were working in a room and every time you made a minor, unimportant, mistake a specific person called you out. You open the cmd instead of the server console or something minor, unimportant, otherwise unnoticeable and, immediately, this other person calls you out. "You're doing that wrong!" How would you feel about that person? Especially, perhaps, if there were others in the group who did not point those things out? Some folks who read this may be adamant that they would be thrilled to have their mistakes pointed out but, let's be honest here - no one likes to be called out. No one likes to be called out on minor, unimportant things. No one likes to be put on the spot (typing in front of a group) and called out on minor, unimportant things on notes that may never be seen again.
You have a couple of possible solutions here. First - if the typos bother you so badly, why haven't you volunteered to take the notes? Be polite, even joking: "I'm super particular about typos, do you mind if I take the notes?" You may be unaware of the challenge of actively participating in a meeting while taking public notes. Or, alternatively, suggest spreading it around. Let everyone take the notes. If, for whatever reason, that isn't a possibility take a break on commenting on typos and watch other's reactions to those typos. See if other's feel they are important enough to comment, see how they do so, get a sense of the culture of correcting others in your group.
