Hi there, @BRITTANYSCHMIDT ...
I've not used Read Aloud at all, so I cannot speak to the functionality. However, it sounds like Read Aloud is a third-party product. Normally what you'd want to do is to reach out to the designers of Read Aloud to see if they have any plans on making an integration with Canvas. And, if you contact them, you'd want to make sure they are designing an integration that would work with New Quizzes in Canvas (which is also a LTI external tool)...since current Classic Quizzes will eventually be phased out. I'd suggest that you have a chat with your school's local Canvas administrator(s) to see if they'd be willing to research Read Aloud to contact them and see if they have any plans on creating an integration with Canvas.
I hope this will be helpful in some way. Good luck!
