Glossary
Covers both buyer modes — brand-spokesperson terminology and virtual-influencer terminology. No competitor glossary covers both.
Branch A — Brand Spokesperson
An AI avatar is a synthetic on-screen human generated by software to deliver scripted speech in video. The avatar has a face, body, and voice — but no real person appears on camera.
Lip-sync is the accuracy of an AI avatar's mouth movements relative to the audio being spoken. High lip-sync accuracy means viewers cannot detect the audio-to-face mismatch; low accuracy produces a visible disconnect that undermines viewer trust.
Branch B — Virtual Influencer / Stable Diffusion
Character consistency is the ability to generate images of the same fictional person across different poses, outfits, and settings — so that Instagram followers (and AI-detection systems) cannot tell the character has drifted between posts.
LoRA (Low-Rank Adaptation) is a fine-tuning method for image-generation models that teaches the model a specific face or style using 20-50 reference images. The result is a lightweight file that makes the model generate a consistent character every time.
A virtual influencer is a fictional digital character — not a real person — who maintains a social-media presence (typically Instagram or TikTok) with brand deals, followers, and a consistent visual identity. Examples: Aitana López (149K Instagram followers, USD 11K/month in brand deals), Lil Miquela (3M followers), Imma.
