For one or for all?: survey of educator perceptions of web speech-based auditory description in science interactives

The evolution of Web Speech has increased the ease of development and public availability of auditory description without the use of screen reader software, broadening its exposure to users who may benefit from spoken descriptions. Building off an existing design framework for auditory description of interactive web media, we have designed an optional Voicing feature instantiated in two PhET Interactive Simulations regularly used by students and educators globally. We surveyed over 2000 educators to investigate their perceptions and preferences of the Web Speech-based Voicing feature and its broad appeal and effectiveness for teaching and learning. We find a general approval by educators of the Voicing feature and more moderate statement ratings than expected to the different preset speech levels we presented to them. We find that educators perceive the feature as beneficial both broadly and for specific populations while some acknowledge particular populations for whom it remains ineffective. Lastly, we identify some variance in the perceptions of the feature based on different aspects of the simulation experience.
