Which of the following is NOT a mobility aid that DSPs might use?

Voice-output devices are not considered mobility aids because they serve a different purpose. Mobility aids are specifically designed to assist individuals in moving around more effectively and safely. This includes devices like wheelchairs, canes, and walkers, which are all intended to enhance a person’s ability to walk or navigate physical spaces.

In contrast, voice-output devices are communication tools that allow individuals who may have difficulty speaking or who are non-verbal to express themselves verbally. They focus on facilitating communication rather than aiding in physical mobility. Therefore, while voice-output devices are essential for individuals who require support in communicative aspects, they do not function as mobility aids, which is what makes this option the correct answer.
