Voice Cloning
AI technology that replicates a specific person's voice from a short audio sample, allowing text-to-speech generation in that voice. Requires proper consent and is used for personalized narration and branding.
Why it matters
Voice cloning lets AI recreate a specific person's voice from just a short recording, which is both remarkable and sensitive. It matters for creators making narration in their own voice at scale, and for accessibility, like restoring speech for someone losing their voice. But it also raises real consent and fraud concerns, so responsible use requires clear permission. Knowing how it works helps you spot both its benefits and its risks.
In practice
An audiobook narrator records a short sample, then uses a voice cloning tool to produce chapters without spending days in the booth, keeping full control of her own voice. On the flip side, the same technology can be misused to fake someone's voice in a scam call. That's why reputable tools require proof of consent, and why you should treat any surprising voice message asking for money with healthy suspicion.

Attention Mechanism
A technique that allows AI models to focus on the most relevant parts of input data when generating output. In language models, attention determines which words in a sentence are most important for understanding each other word.
Diffusion Model
A type of generative AI that creates images by gradually removing noise from a random starting point. Powers tools like Stable Diffusion, DALL-E, and Midjourney. Works by learning the reverse of a noise-adding process.
Distillation
A technique where a smaller 'student' model learns to replicate the behavior of a larger 'teacher' model. Produces compact models that retain most of the teacher's capability while being faster, cheaper, and deployable on smaller devices.
