Can a voice input system be used by people with visual impairments?
It is a common assumption that people with visual impairments would benefit from voice input because they do not need to look at the keys on a keyboard. This is incorrect. Due to the need to make corrections, people who are not able to see the monitor well enough fix the computer’s errors may have trouble using this type of technology. Although voice output technology can be combined with voice input technology to ‘echo’ each word that is spoken (e.g., JawBone product), this can be technically challenging and mentally fatiguing. We generally recommend that voice input be used by people with visual impairments only when the individual also has a physical disability that makes standard entry methods (such as touch typing) impossible.
