The problem to investigate
Useful training videos may be available in a language that learners struggle to understand or without captions for deaf viewers. Automated subtitles can be inaccurate, especially for code-switching or technical terms.
02 / THE BLUEPRINT
A possible solution
Create a small service producing time-synchronised captions and locally reviewed translations. Sell finished accessible files to training organisations while paying translators and reviewers fairly.
03 / THE BLUEPRINT
Start without an app
Begin with volunteer-authorised subtitles for one openly licensed short lesson before investing in specialised software or a studio.
04 / THE BLUEPRINT
Technology that could help
Use transcription software as a first draft, not the final authority. Human language reviewers check technical vocabulary, speaker meaning, timing and accessibility; store source media only with permission.
05 / THE BLUEPRINT
Your first experiment
- Choose one training provider and obtain written media-use permission.
- Translate a short public lesson into one relevant language.
- Ask five target learners and a native-language professional to check accuracy and readability.
- Quote the full cost per finished minute and secure an initial paid order.

People, resources and cost drivers
Customers: vocational schools, online educators, SMEs producing training and accessibility programmes. Resources: translators, caption editors, consent, software, quality assurance and secure media storage. Revenue: per-minute localisation and ongoing catalogue maintenance.
07 / THE BLUEPRINT
What to validate — and when to stop
Validate that clients actually distribute the finished captions and that learners understand them better than the original unsupported material. Compare review time to price.
08 / HYPOTHESIS TO TEST
Potential impact and how to measure it
Track corrected errors per minute, client retention, timely delivery, learner comprehension and fair effective pay for reviewers.
09 / THE BLUEPRINT
Risks and safeguards
Bad translations in medical, legal or safety instruction can injure people. Use subject experts for specialist material, respect copyright and avoid invented translations for low-resource languages.
10 / THE BLUEPRINT
Who might pay or maintain it
Build a language-specialist network, reusable term glossaries and transparent revision fees. Maintain consent and ownership terms for source recordings.
