reading text in a text field on a webpage with voice over and a bluetooth keyboard?/

does anyone know how you can read over text you have written in a textfield on a webpage with bluetooth keyboard as I cant seem to do it...when on the email app/ or on pages moving the up and down arrows work fine, but on a webpage whilst it does move through the text i have written voiceover doesnt read it allowed. I cannavigate through words by pressing option rig‘‘‘“ ht arrow etc but not the whole thing changing the rwter to lines doesnt help either...its like with what i have just written for example with the keyboardI cant read back over it.
