Google Accessibility is Google's effort to make information available to everyone, regardless of disability. They have created alternative access models to help people with visual impairment, color deficiency, deafness, and limited dexterity. They have created keyboard shortcuts, video captions, high contrast video, text-to-speech, and more.
They have created talking RSS Readers for their mobile Android platform, as well as adding accessibility support to their Google Chrome web browser.
You can find a list of all of the accessibility resources HERE.
These accessibility resources are great for special education classes, special needs students, and ELL students.
