When you make a mistake that will require correction, repeat the sentence
containing the mistake and continue.

When you finish the recording, delete the fragment containing the error.

This is really the cleanest and simplest way to handle that. I do this
all the time when I'm reading script. If I stumble or mispronounce, I
go back to the start of the sentence or paragraph and do another take
and keep going, marking the spot on my script so I can edit it later
while I listen to the playback. No need to shuttle, NTTAWWT.
