1193.41(d) Operable without hearing.

Explanation

Provide at least one mode that does not require user auditory perception.

Strategies

1. Individuals who are deaf or hard of hearing cannot locate or identify controls that require hearing. Products that provide only audio prompts cannot be used by individuals who are deaf or hard of hearing. For example, a voice-based interactive product that can be controlled only by listening to menu items and then pressing buttons is not accessible. By addressing the output issues under section 1193.43(d) many accessibility problems that affect input under this section can be solved.

2. Some strategies include:

1. Text versions of audio prompts could be provided which are synchronized with the audio so that the timing is the same.
2. If prompts are provided visually and no speech or vocalization is required, most problems associated with locating, identifying, and operating controls without hearing will be solved.
