Open Mouth Icon - Expressive Line Art for Communication & Design #3706627 (License: Personal Use)

This vector-style illustration features a bold, black outline of human lips parted wide, revealing upper teeth and a prominently extended tongue. Subtle contour lines add dimension to the lips and tongue, enhancing realism while preserving a clean, graphic aesthetic suitable for digital interfaces or print media.

Commonly used in UX/UI design for voice-input prompts, language-learning apps, emoji alternatives, or health/therapy materials illustrating articulation or oral motor exercises; matches user intent for expressive, non-photorealistic visual metaphors.
