Why Businesses Should Add Audio Description to Training Videos
Businesses that invest in employee training videos are already ahead — but if those videos rely heavily on visual information without an audio track describing what’s on screen, a portion of the workforce is being left behind. Audio description provides spoken explanations of important visual information that may not be conveyed through dialogue or the main audio track. As companies increasingly rely on corporate training videos, employee training videos, and just in time learning resources, audio description ensures every employee can access, understand, and benefit from training content regardless of visual ability.
Modern workplaces depend heavily on video content to teach new skills, onboard new hires, explain complex ideas, and support ongoing professional development. However, when essential information is presented visually without explanation, some employees may miss key details. Adding audio description services helps organizations create accessible training videos that improve learning outcomes, employee retention, and engagement while supporting a more inclusive workplace.
What Is Audio Description in the Context of Corporate Training?
Audio description (also called described video or video description) is a scripted narration of important visual information that plays during natural pauses in the original audio — or as extended audio description on a separate audio track. Unlike a standard voice-over that presents lesson content, audio description specifically covers what is presented visually but not spoken: a process flow on a whiteboard, a label on a diagram, on-screen text listing steps, or a product demonstration.
In corporate training videos — whether screencast videos, talking head videos, interactive videos, or explainer videos — much of the instructional value is carried by what viewers see. When that visual content goes undescribed, people who are blind or have low vision miss critical context. For instructional designers building effective training videos, audio description is not an afterthought — it is a core part of creating video content that works for the entire target audience.
Why Audio Description Makes Training Videos More Effective
It Ensures Every Employee Can Actually Learn From the Video
Effective training videos are defined by one thing: whether the viewer acquires the knowledge or new skills the video was designed to teach. If important visual information — a chart, a workflow diagram, a product close-up — is presented on screen without narration, employees with visual impairments receive an incomplete lesson. Audio description closes that gap. Whether added to existing video or built into the video script from the start through integrated description, it ensures the described video communicates the same learning outcomes to all viewers.
For just in time learning environments — where employees access short training modules at the point of need — this is especially important. A worker who cannot access the visual content of a module at the moment they need it most faces a real barrier to doing their job.
It Demonstrates an Inclusive Workplace Culture
Organisations that provide audio description services for corporate training content send a clear signal: every employee is valued. This matters for new hires in particular, who form their impression of a company’s culture through onboarding. Inclusive corporate training is also directly tied to employee retention and boosting engagement — both with measurable bottom-line impact.
It Supports Compliance with Accessibility Standards
The web content accessibility guidelines (WCAG) — specifically Level AA — require that pre-recorded video content includes audio description of important visual information. Many businesses must now meet these standards for internal digital resources, including learning management systems and training platforms. In regulated sectors such as finance, healthcare, and government contracting, the obligation to provide functionality equivalent to accessible content is increasingly enforceable. Ignoring audio description is a legal and reputational risk.
It Improves Comprehension for All Learners
When a narrator explicitly describes what is being demonstrated on screen — the sequence of steps in a process, the layout of a diagram, which element to click in a software tutorial — comprehension improves for all viewers, not just those with visual impairments. Screencast videos and screen capture tutorials benefit enormously from proper description, since the action is almost entirely visual and can be difficult to follow without someone explaining what is being shown.
Head Videos and Talking Head Formats: When Description Is Needed
Head videos and talking head videos — where a presenter speaks directly to camera — are sometimes assumed not to need audio description because the speaker is explaining content verbally. This holds when the presenter is the sole source of information. However, many corporate training videos in this format include supplementary visual elements: slides behind the presenter, text overlays, diagrams shown during cut-aways, or on-screen text reinforcing key points. When this visual information is not read aloud or described, it is inaccessible. Instructional designers should review the video script alongside the final edit to identify all visual information requiring description.
How Audio Description Is Added to Training Videos
Standard audio description inserts described content into natural pauses in the main audio track — this works well when the video includes sufficient space without disrupting flow. Extended audio description pauses the video to allow enough time to describe dense visual content — complex diagrams, multi-step processes, or rapid on-screen text — before playback resumes.
Both approaches deliver a separate audio track the viewer activates via their media player, leaving the original audio untouched for other employees. Some organisations opt for integrated description, building described content into the narration from the outset — particularly effective when creating new video rather than retrofitting existing video.
Making Accessibility a Standard Part of How You Create Training Videos
Adding audio description to corporate training videos is not a niche requirement — it is a production step that makes the content work for every employee. With the right process and the right production partner, it need not add significant time or cost to a training video project.

Frequently Asked Questions (FAQs)
1. Do all corporate training videos need audio description?
Any training video containing important visual information — diagrams, on-screen text, process demonstrations, screen capture sequences — should have audio description if that content is not already conveyed through the main narration. As a general rule, if a viewer who is blind could not fully understand the lesson from the audio alone, audio description is needed. DUBnSUB offers a content review process that helps training teams identify exactly where description is required before committing to production.
2. What is the difference between a voice-over and audio description in a training video?
A voice-over delivers lesson content — the instructional narration that forms the core of the video. Audio description is specifically focused on describing visual elements that are shown but not spoken: what appears on screen, what actions are performed, what text or diagrams are displayed. The two serve different purposes and can coexist in the same video. DUBnSUB produces both and can manage them within a single workflow for corporate training projects.
3. Can audio description be added to existing training videos?
Yes. Audio description can be added to existing video without altering the original audio. Descriptors work from the existing content to write a timed description script that fits into natural pauses or uses extended audio description where needed, delivered as a separate audio track. Building description into the video script from the start — integrated description — is more efficient, but both routes are fully supported. DUBnSUB handles either approach depending on whether clients are retrofitting existing content or commissioning new production.
4. Does audio description for training videos have to be in English only?
No. Organisations with global workforces often need described video in multiple languages — particularly where employee training videos have already been localised through dubbing or voice-over. Audio description should follow the language of the training content. DUBnSUB provides audio description services in 70+ languages, making it possible to deliver fully accessible corporate training video across international teams without treating accessibility as an English-only requirement.
5. Is audio description a legal requirement for internal training videos?
In many jurisdictions, yes. WCAG Level AA requires that pre-recorded video with important visual information includes audio description. In the US, the ADA and Section 508 apply broadly. In the EU, the European Accessibility Act extends requirements across digital content. Even where the obligation is not yet explicit, accessible training content is increasingly expected by employees, regulators, and corporate governance frameworks. DUBnSUB works with clients to ensure described video output meets the relevant accessibility standards for their operating markets.
6. Will audio description disrupt the viewing experience for other employees?
No. Audio description is delivered as a separate audio track that other employees do not activate — their experience of the original video is unchanged. For viewers who use described video, the description is written and recorded to feel like a natural continuation of the content. DUBnSUB’s production team matches tone, pacing, and voice quality to the original content, ensuring a consistent experience across all versions of the training video.
