Hi Gabriela!
It sounds like you had questions about accessibility features within Rise 360. Happy to share some insight on this!
Adjusting the font and contrast can be accomplished by learners with tools like Helperbird, which does support Rise 360 output.
Typically learners who need a course read aloud are likely using a screen reader such as JAWS, NVDA, or VoiceOver. As well as browser extensions such as 'Read Aloud' for Google Chrome. Rise itself does not contain built-in read-out-loud functionality. However, Rise 360 courses are compatible with screen reader navigation!

Please let me know if you have any more questions!
