Being an English language learner for about 30 years, I still make mistakes.
In a written language, when I have misspelled and noticed it in a timely manner, I simply navigate to a wrong word and edit it.
However, in a spoken conversation, when I use a wrong word, I must stop and correct myself by saying a correct one. I've seen many ways to do that, but I'm still not sure which one to use:
He's going to school...
- ...er... she's going;
- ...sorry, I mean, she's going;
- ...oops, she's going;
- ...I'm sorry, let me restate it from the beginning, she's going;
What is the grammatical and polite way to correct myself in a spoken conversation?
Let's stick to a formal/business context if it matters.
Also, what part of a sentence should I repeat to make it clear?
