Open Mouth Icon - Symbol of Speech, Expression, and Communication #3586299 (License: Personal Use)

This high-contrast line art shows a stylized human mouth wide open, with clearly defined upper teeth and a visible tongue, rendered in bold black outlines against a white background. The design is simplified yet anatomically suggestive, emphasizing openness and articulation without facial context. Its vector-like clarity makes it suitable for digital interfaces, signage, or educational materials.

Frequently used in user interfaces (e.g., voice input prompts), language learning apps, accessibility icons (e.g., speech therapy), or public signage indicating speaking zones or audio features. Matches user intent around communication, vocalization, or sound activation.
