Expanding the Semiotic Scope of GeoGebra by Teaching It to Speak

Abstract

This paper discusses the integration of JavaScript and Google's Text-to-Speech (TTS) technology in GeoGebra, adding voice synthesis to enhance the software's educational use. This allows for verbal communication of concepts, increasing interactivity, accessibility, and semiotic range. Such innovation promotes inclusive education, especially for individuals with disabilities, by making learning materials more accessible and engaging. We highlight this advancement with practical examples, underscoring its significant impact on making education more flexible and inclusive through enhanced GeoGebra functionalities.
