Audio control



Persons who use screen reading software can find difficult to hear the speech output if there is other audio playing at the same time, especially if the screen reader’s speech output is controlled with the same volume control as the sound playing in background (W3C, n.d.).


  • Having control of the volume means being able to reduce its volume to zero.
  • Playing audio automatically when landing on a page may affect a screen reader user’s ability to find the mechanism to stop it because they navigate by listening and automatically started sounds might interfere with that navigation.
