How do I increase my accuracy while typing at a good speed ?

I start to look at my keyboard when I don't get good accuracy and read the text then type but then again I have a good memory

Just play more. You got this! In about last month my wpm was around 50-60 I'm spamming this game and now my wpm 80-100 so keep going don't give up ✔

You know, what slows down people, Special Characters and Numbers, you can practice those from the basics. I guess you will hit a good accuracy after you have a good muscle memory on all letters.

What's important is muscle memory and when you try to go fast without developing that muscle memory you're bound to make mistakes. Maybe try going for a high accuracy every match until you feel comfortable with it, then you will naturally speed up.

This same is happening with me, I am focusing on the accuracy keeping the speed aside. This helped me a lot you should also give it a try and in no time you will see your speed also improving with low errors.
