What is Audio Description?

The visual made verbal — a powerful art form and essential accessibility tool that transforms the visual world into a vivid auditory experience.

Transforming sight into sound.

Audio Description (AD) is a powerful art form and an essential accessibility tool that transforms the visual world into a vivid auditory experience. It translates visual information into spoken words for people who are blind or have low vision and is compliant with international standards.

It describes what sighted audiences can see but that is not conveyed through dialogue alone — such as actions, facial expressions, scene changes, on-screen text, costumes, and settings. This detailed narration is seamlessly integrated into the natural pauses of a program’s original soundtrack, making the story clear and complete through sound.

At its core, audio description is about equitable access — ensuring that visual media and environments are usable by everyone.

  • Film & Television: Movies, series, documentaries, commercials, and online video content.
  • Live Performances: Theatre, dance, concerts, sports, festivals, and all types of live events.
  • Museums & Heritage Sites: Audio-described exhibitions, galleries, monuments, and guided tours.
  • Education: Learning materials, diagrams, visual teaching aids, and e-learning platforms.
  • Digital & Marketing Content: Social media videos, brand visuals, presentations, and corporate communications.
  • Public Spaces & Tourism: Audio-described environments that support independent navigation and engagement.
  • Illustrated Books & Podcasts: Bringing visual stories and graphics to life through sound.

Experience Audio Description — with and without.

AD does not simplify content — it completes it. It fosters social inclusion by allowing participation in shared cultural experiences like watching films with family and friends.

The Value of Audio Description: Empowering Visually Impaired Persons

For the approximately 1 million visually impaired people in South Africa and almost 300 million worldwide, Audio Description is more than just a service — it’s a gateway to independence, participation, and inclusion.

Blind and visually impaired people do not lack imagination or understanding — they lack access to visual information. Much of modern communication relies heavily on visuals. Without audio description, blind users are often excluded from:

  • Storytelling and emotional nuance
  • Contextual understanding
  • Cultural participation
  • Independent decision-making

Audio Description restores access by supporting independence, enabling equal participation, enhancing dignity and autonomy, and providing full narrative comprehension.

AD does not “simplify” content — it completes it. It fosters social inclusion by allowing participation in shared cultural experiences like watching films with family and friends, and ensures that visually impaired persons are not left behind in an increasingly visual digital world. By providing access to information and entertainment, AD empowers individuals to be more informed, engaged, and ultimately, more employable and contributing members of society.

Accessibility is shifting from nice-to-have to necessity.

Globally, accessibility is shifting from a “nice-to-have” to a legal, ethical, and commercial necessity. The Audio Description market is experiencing significant growth, driven by:

  • Exponential Growth of Video Content: The global shift towards video as a primary communication and entertainment medium necessitates accessible solutions.
  • Aging Global Population: With an estimated 596 million people with distance vision impairment worldwide in 2020, projected to reach 895 million by 2050, demand for accessible solutions is rapidly increasing.
  • Increased Demand for Accessible Streaming Content: As streaming platforms dominate, the expectation for inclusive content grows.
  • Accessibility Requirements in Broadcast Licensing: Regulations are increasingly mandating accessibility with prescribed targets for audio description.
  • Inclusive Tourism Initiatives: Making travel and cultural experiences accessible to all.
  • Disability-Led Innovation in Media Technology: Driving new solutions and advancements.
  • Growth of Assistive Technology: Powered by AI and mobile platforms, enhancing accessibility.
  • Growing Demand from Visually Impaired: A powerful consumer group actively seeking and willing to pay for accessible content.

Audio Description is increasingly recognised as a standard component of professional media production, not an add-on. The global Audio Description Services market was USD 354 million in 2022 and is projected to reach USD 587 million by 2032 (CAGR of 5.6%).

Key drivers behind the growth of Audio Description.

  • Global disability inclusion policies
  • Growth of AD availability and streaming and on-demand media
  • Increased awareness of accessibility rights
  • Mobile technology adoption
  • Legal frameworks enforcing access to information
  • Advocacy from blind-led organisations

A global need — not a niche requirement.

People worldwide live with some form of visual impairment

43M

People globally are blind, with hundreds of millions experiencing moderate to severe vision loss

These figures illustrate a critical access gap between visual media and blind audiences. Audio Description bridges this gap by transforming visual information into meaningful audio, enabling equal participation in cultural, educational, and digital experiences. Accessibility is not a niche requirement — it is a global need.

  • Limited Access to Media: The majority of films, television programmes, and online videos are still released without Audio Description, excluding blind and visually impaired audiences.
  • Accessibility Expands Reach: Accessible media benefits not only blind users, but also older persons, neurodivergent audiences, language learners, and audio-first users.

Benefits Everyone

Accessibility improves usability for everyone.

While Audio Description is essential for blind and visually impaired users, it also benefits many others:

  • Older persons with age-related vision loss: Who may experience declining vision.
  • People with cognitive or learning disabilities: AD helps decipher on-screen expressions and social cues, reinforcing information visually and auditorily.
  • Neurodivergent audiences: Providing additional sensory input and context.
  • Language learners: Offering additional context and understanding.
  • Users in screen-free or audio-only environments: Such as while driving or multitasking.
  • Children: Stimulates linguistic development by connecting words with actions and expanding vocabulary.

Accessibility is a fundamental right.

Shazacin is committed to upholding and advocating for these rights, aligning with key national and international legal instruments.

In South Africa, accessibility in broadcasting is supported by the ICASA Code For Persons With Disabilities Regulations, which promotes equitable access to information and communication services. This requires public broadcasters, commercial free-to-air, subscription services, and community broadcasters to significantly increase their AD content aligned with prescribed percentages.

Internationally, Audio Description is aligned with:

  • United Nations Convention on the Rights of Persons with Disabilities (CRPD)
  • Sustainable Development Goals (SDGs), particularly Goal 10 (Reduced Inequalities)
  • Web Content Accessibility Guidelines (WCAG 2.0 Level AA)
  • The Americans with Disabilities Act (ADA) & The Rehabilitation Act (USA)
  • The 21st Century Communications and Video Accessibility Act (USA)
  • The British Communications Act and the Equality Act 2010 (UK)
  • The European Accessibility Act
  • International broadcasting and accessibility standards

These frameworks recognise access to information as a fundamental human right.
