Audio Output (6 of 7)

Issue: Voice output is not repeated.

Users may fail to hear or understand voice output messages when they are first presented. If the messages do not repeat, either automatically or under user control, then users may be unsure how to proceed with their interactions with the device.

Populations Impacted: Users with cognitive impairments; users who are hard of hearing; users who are blind; users with low vision.

Potential Solutions:
  • Repeat voice messages automatically if the user does not respond within some period of time. If the user fails to respond or take action within a reasonable amount of time (a few seconds) after a voice message is presented, repeat the voice message.

  • Provide a control that allows the user to request that voice messages be repeated. This will allow users to listen to messages again if they did not hear or understand the message initially. Ideally, the repeat control should be a physical control (as opposed to an on-screen control) and should be tactilely discernible to increase the accessibility of the control for users with visual impairments.
