Fake AI videos with the voice of astronomer Jiří Grygar on YouTube, family files criminal complaint

only one source so far

Fake videos with a synthetic voice of astronomer Jiří Grygar talking about God and aliens have appeared on YouTube. YouTube did not respond to the takedown request, so his son Lukáš Grygar filed a criminal complaint.

A channel has appeared on YouTube with videos in which a synthetic voice imitates astronomer and science popularizer Jiří Grygar. At first glance the videos look like recordings of lectures, but according to the source the entire content is in fact generated using artificial intelligence, and it covers topics such as God, aliens, or the afterlife. Jiří Grygar has nothing to do with this content.

According to the source, the family tried to get the videos taken down directly through YouTube, but the platform did not respond to the request. The astronomer's son, Lukáš Grygar, therefore filed a criminal complaint.

For details, see the source article.

What changed

Why it matters

The case demonstrates that an AI-generated voice can be misused to spread disinformation under the name of a real and trusted public figure, and that relying on a quick resolution from the platform may not be enough — according to the source, YouTube did not respond to the takedown request, so the aggrieved party had to resort to filing a criminal complaint.

Two audiences, two different impacts

What this means

01

For individuals

It turns out that the voice and likeness of a publicly known person can be misused by AI without their knowledge to spread false content, and that reporting it to the platform may not lead to a quick takedown — it is therefore useful to also know the route of filing a criminal complaint.

What to do If a suspicious video appears featuring your voice or likeness (or that of someone close to you), preserve the evidence, report the content to the platform, and if that is unsuccessful, consider filing a criminal complaint.

02

For a business

The case illustrates the risk for companies and platforms: according to the source, YouTube did not respond to the takedown request, which increases legal and reputational risk both for platform operators and for companies or individuals whose likeness or voice can be misused by AI without their consent.

Risks and compliance
What to decide Monitor whether the company's name, voice, or the face of company representatives appears in falsified AI-generated content, and have a procedure ready for reporting it and, if necessary, filing a criminal complaint.
