If this is specifically for blind users, many use external text to speech tools like JAWS, NVDA and Windows Eyes. JAWS also supports alternate accessibility technologies like tactile braille devices.
So you need to look at this problem from a different perspective. How you code your website makes a hug difference to these text to speech tools.
The WC3 set up the Web Accessibility Initiative (WAI) and they created the Web Content Accessibility Guidelines (WCAG 2.0) to help developers create webs sites which work for everyone. These guidelines are technology agnostic (although they have many supporting documents related to web technologies).
A good place to start is here: https://www.w3.org/WAI/ and https://www.w3.org/TR/WCAG20/
You should also understand Accessible Rich Internet Applications (ARIA) because these can be added to your html to further help blind users who use screen readers https://www.w3.org/WAI/intro/aria
