How do I stop Android speaking my commands? Suddenly (OK so I may accidentally have triggered a setting somewhere) my android phone (LG v20 Standard Android) has started speaking all the touch commands I do.

For example, if I start from a blanked locked screen and turn it on the device says
"Screen on. the time" Then after a pause, "Screen Off" as it turns off the screen

If I type in characters it speaks every letter/character as I press the key (makes passwords tricky!!)

If I try to close an app with the X  I
press the x it says "Dismiss button. Double tap to activate"
I double tap and it says " app dismissed"

But worst of all swipe no longer works. So I cant swipe up to see what is on the bottom of a page; I cant swipe left to see other pages of apps etc etc

Please, how do I get back to a normal silent android!

Method 1

Tap Home key > Tools > Settings > General tab > Accessibility > Vision. Then, disable Talkback

Method 2

Hold Volume Up + Volume Down for more than 3 seconds to disable (or enable) Talkback as described in this answer from XDA.
