AI for creating employee training and eLearning content

Training content creators at the US Marshals Service, part of the Department of Justice, have piloted TechSmith Camtasia and Audiate since September 2025 to generate on screen presenters and realistic narration from text, and to produce voice audio in a range of voices and tones without recording actors. The goals are to shorten the time to release training material, support Section 508 accessibility and improve the online learning experience. No outcome figures are published.

The Veterans Benefits Administration uses the AI Assistant in Articulate 360 to create interactive eLearning for its claims processors more efficiently. The assistant generates text to voice audio, images, outlines, polls, quizzes and sounds for courses. The inventory entry says engaging eLearning reduces instructor burden and classroom time, that efficient training development reduces instructional design burden amid decreased hiring abilities, and that the time saved in developing training brings cost savings, without a figure. The inventory lists it as deployed; no outcome figures are published.

IRS training developers used to record course narration with employees and microphone kits; with return to office mandates that was no longer possible. Since May 2024 they enter narration scripts into a web based AI voice tool that returns audio files for import into eLearning authoring applications. Scripts contain no personal or taxpayer information and use fictitious names and addresses. The IRS reports better quality, a wider choice of voices and much faster generation and revision of voiceovers, but publishes no figures.

Northumbria Healthcare, an NHS trust with more than 12,000 staff in 10 hospitals, received compulsory national training as generic online packages and rebuilt each revision by hand over weeks. Its learning and development team, which the page says switched to Synthesia three years before publication, now makes short avatar videos that add local hospitals, rules and familiar faces to the national content, and moved facilities management safety briefings into short videos. Synthesia reports 86% less time per video and more than 1,000 videos from a small team. The figures come from the vendor's case study.

Ryanair records a real instructor once and delivers engineer training through a lifelike Synthesia avatar instead of flying instructors between its 13 European bases, and uses the same avatars to send passengers short videos explaining flight disruptions. Ryanair trains around 1,300 of its 3,000 engineers every year, and Synthesia reports the same approach has spread to 15,000 cabin crew and to turnaround procedures for 22,000 ground agents in 20 languages. The case study reports six figure savings from moving engineer training out of the classroom, without an exact figure. Its one hard number, disruption videos going out up to 90% faster, concerns passenger communication rather than training, so it is not recorded as a metric here.

Five Below's eight person talent development team supports about 2,000 stores. Agency made training videos cost roughly $12,000 each, about $60,000 in one year for five videos, so many topics went unmade. In its first full year on Synthesia the team made more than 100 training videos for $40,000, and classroom trainers began building videos themselves. Synthesia reports a 97% cut in per video cost, $240,000 of agency cost avoided and learner favorability above 90%. These are figures from the vendor's case study.

Komatsu's training team in Europe trains a network of 211 distributors in 151 countries on machine features, operation and technical specifications. After trying slides with computer voiceovers and external multimedia agencies, it built explainer and product training videos with a branded "Komatsu Studio Avatar" in HeyGen, written in English and translated into German, French and Italian. Other Komatsu entities adopted the approach, and an all employee human rights course was translated into 14 languages. The team reports that 80 to 90% of viewers now watch a whole video, where they used to stop after ten minutes, and that quiz results improved. These are statements in the vendor's case study.

Merck KGaA piloted Synthesia with a handful of users and, in early 2025, centralized it as an approved tool open to all employees across its Healthcare, Life Science and Electronics sectors. Teams use it to turn quality transformation training that once ran to 200 slide decks into video, to give a senior leader's avatar a voice in Korean and Spanish at executive conferences, and to have enablement content ready in nine languages the moment new tools launch. Synthesia reports an internal survey found hundreds of hours saved a year, without a precise figure, and that content which used to take months now takes days.

Mondelez brought supply chain training video production in house with Synthesia instead of briefing outside agencies for a four person team supporting more than 150 manufacturing plants globally. Synthesia reports training that once took months now goes live in one to two weeks, that the team more than tripled annual output without adding headcount, and that a video an agency had quoted at around $50,000 to rebuild and localize was recreated internally in a single day. The case study also reports higher employee engagement from localized, scenario based video learning, without a baseline figure to compare it against.

Novelis, the aluminum producer with about 13,500 employees, had operations training made by outside vendors in English only, taking four to six weeks per course, and outsourcing the creation and translation of the videos into eight languages cost close to $1 million. Its operational excellence team now builds the Novelis Operating System training in house with Synthesia avatars, published in ten languages in a digital learning academy. Synthesia reports about 85% lower localization cost, course creation cut from 1.5 months to 1 week, and more than 3,000 training videos in one quarter. The figures come from the vendor's case study.

Sibelco, the Belgian industrial minerals company, used to make training videos with actors, travel to sites around the world and separate edits for each language, which took months. Its digital learning team now makes safety and corporate training videos in house with HeyGen avatars and text to speech, and updates them when policies change. HeyGen reports that production time fell within six months and that the team now saves 1,000 euros for each minute of training content. The figure comes from the vendor's case study and does not net out license costs.

Sky Italia's learning team enables thousands of employees in Italy and Eastern Europe, and used to hold back a new product until trainers had covered everyone, which took over a month. It replaced long classroom sessions and agency made videos with short digital learning paths built in house with Synthesia avatars. Synthesia reports that onboarding staff on a new product fell from one month to one week, as for the Sky Mobile and Sky Stream launches, that new learning professionals reach productivity in two weeks instead of about three months, and that the team maintains more than 100 new learning paths a year. The figures come from the vendor's case study.

Heineken's Global TPM Manager of Customer Service and Logistics uses Synthesia to train employees worldwide in continuous improvement concepts, replacing generic PowerPoint decks that mostly existed only in English. Synthesia reports the videos have trained 70,000 employees with localized training reaching 170 countries, and that one click translation lets the same message reach staff in their own language within minutes instead of the half a day or more a simple two minute video used to take to produce. These are vendor stated figures from a case study, not an independently measured saving.

LATAM Airlines' training team builds regulatory and technical courses for cargo, cabin crew, sales and support areas. Recording voices and actors was slow and costly, and any policy change meant a reshoot. The team now writes a script, picks a Synthesia avatar and regenerates the video when the policy changes, with Spanish, Portuguese and English versions from one click translation. Synthesia reports more than 300 videos reaching over 16,000 learners and a production time cut from 30 to 60 days down to 5 days at most. The figures come from the vendor's case study.

Since 2023, Carlsberg's Integrated Supply Chain Academy has built training in house with Synthesia instead of external video agencies, and use has spread to shop floor onboarding, one point safety lessons, procurement training and change management content. A document, usually a PDF, goes into the tool's AI Assistant, which scaffolds the structure; the video is built in a branded template, generated in English and translated for each market.

Synthesia reports that more than 100 employees have built content in under two years, that three agency shoots a year (its conservative baseline, at least €30,000 in fees) no longer sit on Carlsberg's P&L, and that the second supplier once hired to translate each eLearning is no longer needed. These are vendor stated figures, not a measured saving net of license costs.

Zoom's instructional designers train more than 1,000 salespeople on selling its products. When training material changed, whole videos had to be recorded again, with subject matter experts spending a day in front of a camera for about 15 minutes of usable footage. The team now produces AI avatar videos with Synthesia and builds them into interactive modules in Rise 360 and Storyline.

Synthesia reports 90% time savings on video creation, more than 200 micro videos from one designer in about six months, 15 to 20 hours a month freed for Zoom's subject matter experts who no longer record themselves (the page does not say whether this is per expert or in total), and monthly cost savings of $1,000 to $1,500 per employee previously spent on creating training videos.
