Something pretty incredible is happening at the Imperial War Museums (IWM). They’ve joined forces with Capgemini and Google Cloud to dig into over 20,000 hours of old audio recordings real stories told by people who lived through war. The twist? They’re using AI to do it.

For years, these recordings thousands of them were just sitting there. Not forgotten, but definitely hard to reach. They weren’t transcribed, weren’t searchable, and frankly, most people didn’t have time to listen through hours of audio. So, they stayed hidden.

What They Did

Together, IWM, Capgemini, and Google Cloud built an AI-powered system that listens to the recordings, transcribes them, and even figures out who’s talking, what they’re talking about, and when. It’s not just turning speech into text it’s pulling out names, places, military units, and key moments, then organizing it all in a way people can actually use.

And what would’ve taken decades to do by hand? The AI is getting it done in weeks.

Why This Matters

Let’s say you’re researching your grandfather’s battalion or looking for personal stories about a specific battle. Before, you’d have to sift through hours of audio manually if you could even find it. Soon, you’ll be able to go to IWM’s website, type a question, and get an instant answer pulled directly from the interviews. You can even listen to the exact moment someone said it.

Nick Hodder from IWM put it well: “We’re opening up our history, not just making it available, but making it understandable.”

The Human Touch

This isn’t just a tech job. Real historians and curators were part of the process, making sure the AI didn’t misinterpret accents, war terms, or historical facts. That balance AI speed with human knowledge made a huge difference in quality.

So, How Good Is It?

In tests, the system got 99% of the words right and did a great job figuring out who was speaking. And the interface they’ve built? Super simple. You can type in questions, browse interviews, or read summaries, all from the same place.

Steven Webb from Capgemini said:“This is what AI should be doing helping us connect with stories that matter.”

And John Abel at Google Cloud added:“History isn’t just in books. It’s in voices. And we now have the tools to hear them properly.”

What’s Next?

IWM isn’t stopping here. They’re planning to use more AI always working alongside human experts to bring even more of their massive collection online and make it meaningful to more people, from researchers to students to anyone curious about the past.

FAQs

1. How is AI used in oral history transcription?

It listens to the audio and turns it into searchable text. But it goes further spotting names, places, and themes so users can explore interviews more easily.

2. Why does this project matter for history lovers?

Because it opens up thousands of personal stories that were basically buried. Now, anyone can search and listen to them no special access or expertise needed.

3. Is the AI accurate?

Yes and curators double-checked it. The system reached 99% word accuracy and did a solid job of identifying different speakers and complex war terms.
