Not necessarily. If I'm entering text and I made or think I may have made a mistake, I have the message read. Then, since I'm immediately after the mistake, if there is one, I back space until I think I've deleted the error or the word with the error and then I have the message read again. I then write the word again. I may have to go a carachter or two bback until I hear the last carachter of the previous word is missing so I know exactly where I am starting from. I don't want to write the corrected word with no space between the previous word and the word I'm correcting. Or I may go back until I hear that the first letter of the word I'm correcting is still there or the first two letters. it depends on if I can definitely tell what is there. Sometimes, its difficult such as in the case of a double letterr. In the word correct, for example, I would go back until just co was read.

However, my phone has limited use of the Google assistant and I've started dictating most of my messages, which, although it introduces errors that may not be picked up with the not very good screen-reader in the phone, produces understandeable messages and is much faster than using the numpad input. Sometimes, I have to dictate a message two or three times but even so, that's often faster and easier than writing it.

I'll add that my phone reads whatever is there of the current word if I press the space bar, placing a space after the word or part of the word. That often speeds things up a lot if I am editing in this way.
