Definition

A synthetic media product (image, video, audio) in which a person's likeness is convincingly replaced with another's using artificial intelligence and machine learning techniques.
The technology or practice of creating such synthetic media; by extension, something that is deceptively manipulated or fabricated to appear authentic.

Frequency
Slightly higher frequency in American English due to the term's origin in US-based Reddit forums and its prominence in US political discourse.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as "глубокая подделка" which is a calque and not used. The common term is "дипфейк" (deepfake). Do not confuse with "фейк" (fake), which is broader and less technical.
- "Видеомонтаж" or "поддельное видео" are more general and do not capture the AI-specific nature.
Common Mistakes
- Using it as a mass noun (e.g., 'There's a lot of deepfake online' – better: '...many deepfakes').
- Overapplying it to any edited video rather than specifically AI-synthesised content.
- Misspelling as 'deep fake' (though the spaced form is becoming accepted).

FAQ
Frequently Asked Questions
It is most commonly written as one word ('deepfake'), though the spaced form 'deep fake' is also seen. The one-word form is dominant in technical and journalistic writing.
Yes. While initially associated with video, the term now encompasses highly realistic, AI-generated audio impersonations, often called 'audio deepfakes' or 'voice deepfakes'.
No. While often discussed in the context of harm (fraud, defamation, political manipulation), the technology has legitimate uses in filmmaking (for dubbing or de-aging actors), education, and accessibility.
A 'cheap fake' uses simpler, non-AI editing techniques (like speeding up video, splicing clips, or using basic Photoshop) to mislead. A deepfake specifically relies on powerful AI and machine learning models to generate or manipulate content.
