Text-to-speech technology reads the words on a screen aloud. This can support learners with vision difficulties or provide a bimodal experience when combined with reading text. Adult learners may be faced with vision decline, which can impact Attention, change color perception and sensitivity, and create contrast sensitivity. Text-to-speech can mitigate the negative effects of these declines while also supporting learners with reading challenges such as dyslexia. The assistive technology can also improve Foundational Reading Skills such as decoding, vocabulary, and reading rate.
