Learning Ally(formerly Recording for the Blind and Dyslexic) is a great place to volunteer! They have 1.5 to 2 hour sessions where you record yourself reading all types of materials from novels to textbooks. These materials are then used by people who are either blind or have a visual learning disability. John and Tim the Learning Ally staff are super friendly and helpful when you have questions. I would recommend spending your time volunteering at Learning Ally!
