AI Audio Description
AI audio description uses multimodal AI to automatically generate timed narration tracks that describe the visual elements of video content. It replaces weeks of manual scripting with a platform workflow that produces broadcast-grade audio descriptions in hours — across multiple languages, at a fraction of the cost.
How It Works
Video analysis
Multimodal AI processes the video frames, audio track, and subtitles simultaneously. It identifies characters, objects, actions, spatial relationships, scene transitions, and what information is already conveyed through dialogue and sound.
Description generation
A large language model generates natural-language descriptions timed to fit in dialogue gaps. The system applies audio description guidelines: describe what is visually significant, stay objective, prioritize narrative relevance, and avoid repeating what the viewer can hear.
Voice synthesis
Text-to-speech converts the timed script into narrated audio output, matched to the correct positions in the video timeline. The result is a complete audio description track ready for mixing or delivery.
Review and delivery
Teams can review, edit, and approve the generated audio description before final delivery. The workflow is designed so that human effort focuses on quality assurance and edge cases rather than drafting from scratch.
Why AI
The shift is driven by three forces: regulatory deadlines are accelerating, content volumes are growing faster than the supply of trained describers, and AI quality has reached a level where it handles the majority of content reliably.
Manual audio description costs $15–50 per finished minute and takes weeks. AI reduces cost to $5–20 per minute and compresses turnaround to hours, making full-catalog coverage realistic for the first time.
Generate audio descriptions in English (US), German, French, Hindi, Italian, Spanish, and Greek from one video analysis pass. Each additional language adds marginal cost instead of requiring a complete new production cycle.
The European Accessibility Act, ADA Title II, FCC CVAA, and Ofcom quotas all require audio description. AI makes compliance achievable across large catalogs and ongoing production without blowing accessibility budgets.
AI does not get tired, forget character names, or vary in style across a season. It produces consistent output that human reviewers can then refine, reducing the quality variance that comes with managing multiple manual describers.
Upload a video, choose your language, and get results — all from your browser. No procurement cycle, no vendor coordination, no waiting on quotes. Start with a free account and scale when ready.
Streaming platforms and universities with thousands of hours of back-catalog content can finally address the backlog. AI changes the economics from "impossible at manual pricing" to "achievable in months."
AI vs Manual
The two approaches serve different operating models. Understanding where each is strongest helps teams choose the right workflow for their content.
AI reduces the per-minute cost by 60–87% by automating scripting, timing, and voice synthesis. Manual AD carries higher labor costs across every step from viewing to studio recording.
AI processes video in minutes and returns usable outputs the same day. Manual workflows typically require 2–4 weeks per hour of content, with rush delivery at premium pricing.
AI scales horizontally — process hundreds of hours per day. Manual AD is limited by the number of trained describers available, which creates bottlenecks during peak demand.
AI generates AD in English (US), German, French, Hindi, Italian, Spanish, and Greek from a single video analysis. Manual multi-language AD requires separate scripting, voice talent, and studio sessions for each language.
AI produces consistent output across a season or catalog. Manual AD quality varies with different describers, vendors, and project timelines.
Prestige theatrical content, highly artistic visual storytelling, and content requiring deep cultural interpretation still benefit from expert human describers. The strongest model combines AI drafting with human review.
