Examples:

"All sorts of deepfakes are possible. Face swaps, where the face of one person is replaced by another. Lip synchronization, where the mouth of a speaking person can be adjusted to an audio track that is different from the original. Voice cloning, where a voice is being 'copied' in order to use that voice to say things." — Julia Bayer and Ruben Bouwmeester, DW.com, 14 Jan. 2022

Did you know?

The old [maxim](https://www.merriam-webster.com/dictionary/maxim) "things aren’t always as they seem" seems more true than ever in the age of deepfakes. A deepfake is an image, or a video or audio recording, that has been edited using an algorithm to replace the person in the original with someone else (especially a public figure) in a way that makes it look authentic. The fake in deepfake is transparent: deepfakes are not real. The deep is less self-explanatory: this half of the term is specifically influenced by deep learning—that is, machine learning using artificial [neural](https://www.merriam-webster.com/dictionary/neural) networks with multiple layers of [algorithms](https://www.merriam-webster.com/dictionary/algorithm).
