iPhone and iPad users who can't see well enough to read these web pages can have them spoken using a feature called VoiceOver. A lot of this web site is devoted to learning how to make full use of VoiceOver but you may be able to get by with just a little knowledge of VoiceOver and perhaps some initial telephone or in-person support.
Please begin by checking out Apple's video on VoiceOver basics.
VoiceOver can be turned on and off using Siri. Say "Hey Siri, turn VoiceOver on" or "Hey Siri, turn VoiceOver off". If you have enough vision to tap on links to open web pages, find the page you want to read and then instruct Siri to turn VoiceOver on. VoiceOver will speak what it finds at the very top of the page. You can hear the page spoken continuously by swiping down with two fingers. Speech can be paused and resumed with a two finger tap. If you want to go back a little to listen again swipe left with one finger one or more times and then swipe down again with two fingers to resume continuous reeding from the current position. If you want to skip forward, swipe right with one finger one or more times. Continuous reeding can always be started again from your current position with a two finger swipe down. If you want to start continuous reeding again at the top, swipe up with two fingers.
Many of the longer pages on this site are divided into sections, each with a heading. More advanced VoiceOver users who are familiar with the rotor can set the rotor to headings to move between these headings with a one finger swipe down or up.
If you prefer to avoid VoiceOver for now and have sufficient vision to read the screen but want sometimes to have text spoken to you, Apple have provided a simpler option that lets you have entire pages spoken or alternatively you can have sections of text spoken just by touching them. You will find full details at "how to have screens and sections of screens spoken on iPhone and iPad".
