 we provide text-to-speech technology, and this allows learners to listen to the course material, to the content within you. So besides all disabilities, there's a whole bunch of people that just have an auditory preference. And we always call this the podcast effect. So if you give people the choice to listen to a podcast about a certain informative topic, or read a book about the same topic, nine out of ten times, when people go for the easy route and listen to the podcast, they'll prefer the audio. And that's what we provide. So our technology allows users in Moodle to listen to the content, to give them that choice. And they can meet along with highlighted text and all kinds of assistive features if necessary, but that stimulates them to visually and auditorily engage with the content.
