Jo Sykes

 is an audio describer who voices a special audio track that is available during the broadcast (and sometimes the DVD releases) of many television shows. In this capacity, she works for Red Bee Media, a company contracted by the British Broadcasting Corporation, and not specifically the Doctor Who production team.

The track she and her colleagues provide is of special use to the visually impaired, as it gives a more visual description of events than would be conveyed by the standard audio track alone. During initial broadcast of Doctor Who episodes in the United Kingdom, this track can usually be accessed via the Red Button.

She was interviewed on the Doctor Who Confidential episode associated with The Hungry Earth to explain the service she provides for differently-abled Doctor Who fans.
