Audio descriptions

We create audio descriptions for video: by voice we describe the important visual events not present in the dialogue — for blind and low-vision users. So that a blind person understands not only what is said but also what is shown. Honestly upfront: this is needed NOT for every video, but for ones where the visuals carry meaning not voiced in the dialogue; it is live human work by volume, and sometimes an extended version of the video is required (with pauses for the description).

Audio descriptions — overview

Audio descriptions — price, timeline & scope

Audio description is adding voice descriptions of significant visual content of a video in the pauses between lines: what happens on screen, who appeared, important actions, on-screen text, scenes — what a sighted person sees and a blind person misses without description. Honestly about applicability, this is key: audio description is needed NOT for every video. If everything important is voiced in speech anyway (e.g. a talking head, a webinar), a separate description is excessive. It is needed where the visuals carry meaning not in the dialogue (demonstrations, actions, product showing, scenes). We will honestly say whether your content needs it. Honestly about pauses: a quality description is inserted into natural pauses; if there are few, sometimes an EXTENDED version of the video is needed (with added pauses for the description) — that is a separate complexity, we will warn in advance. Honestly about implementation: this is live human work (a description script + voicing), by volume (duration). Honestly about the boundary: audio description is for BLIND users (describes visuals by voice), it is the opposite of captions (811, text of speech for deaf users); they must not be confused, and one does not replace the other. Honestly about the effect: real video accessibility for blind users; we do not guarantee direct sales growth. Honestly about access: source videos are needed. An important boundary: this is audio description; captions are 811, sign interpretation is 813. Picture this: instead of 'a blind person hears the speech but does not understand what is shown' — a voice describes the important visuals. The base price starts from 25,000 ₽ (depends on duration and complexity).

  • A blind person hears the speech but does not understand what is shown.
  • Visual demonstrations and actions are lost without description.

FAQ

  • Is this needed for every video of ours?

    No, and that is honest. If everything important is voiced in speech (a talking head, a webinar), a separate audio description is excessive. It is needed where the visuals carry meaning not in the dialogue: demonstrations, actions, product showing, scenes. We will honestly say which of your videos really need it and which do not.

  • How does audio description differ from captions?

    They are opposite things for different needs. Captions (811) are TEXT of speech and sounds for DEAF users. Audio description is VOICE describing visuals for BLIND users. They must not be confused, and one does not replace the other. For full video accessibility both are sometimes needed; we will honestly say what you need.

  • Why is an 'extended version' of the video sometimes needed?

    A quality description is inserted into natural pauses between lines. If speech is dense and there are few pauses, there is nowhere to insert the description — then an extended version of the video with added pauses is made. That is a separate complexity and scope; we will warn in advance if that is your case.
