Callfinder

The innovative Callfinder® is an electronic device that unlocks printed sound information, transforming your reading experience into an immersive audio-visual journey. This battery-operated device requires no internet connection for normal use and works by identifying unique codes printed as invisible grids of dots on specially prepared pages.

Compatible with all Callfinder® Ready books, this portable device greatly enhances your learning and entertainment experience. Simply point the Callfinder® at coded areas on the page to hear corresponding audio content—from bird calls and mammal sounds to language pronunciation and storytelling.
