Verbal Spectrum is a visual communication app designed to help children express needs, feelings, and ideas using simple, intuitive grids. Built with clarity and flexibility in mind, Verbal Spectrum allows families and educators to create custom buttons, folders, and subfolders, organizing content in a way that feels natural, structured, and easy to understand. Children interact with large visual icons arranged in predictable grids, making communication more accessible and consistent. Icons can be combined to form phrases and sentences, which can be played with narration, helping connect visual choices with spoken language. Personalized Organization for Families and Educators Verbal Spectrum is designed to adapt to different communication needs, allowing parents, caregivers, and educators to personalize content based on daily routines, learning environments, and individual preferences. Folders and subfolders can be customized to organize communication by home routines, classroom activities, learning goals, or personal interests. Icons, colors, and layouts can be adjusted to match each child’s communication style, creating a familiar and predictable structure that supports understanding and independence. This flexible organization makes it easy to build personalized communication systems for both home and educational settings. Learn Folder The Learn folder introduces guided learning activities using visual categories and structured layouts. It supports exploration of actions, objects, routines, and concepts in a calm and organized environment designed for young learners. Learn+ — Sentence Building Learn+ expands communication by allowing children to build complete English sentences using a simple and predictable 3-connector structure. This visual scaffolding helps children organize thoughts step by step: • Helper verb (intent or need): I want to, I need to, I have to • Action verb (what to do): go to, take, finish, eat, play, read • Object / place / time (where, what, or when): bed, my room, school, lunch, book, outside This structure creates clear and repeatable patterns for communication, allowing children to combine icons into meaningful sentences that can be narrated aloud. Examples: • I want to go to bed • I need to finish my lunch • I have to take my book • I want to play outside Key Features • Visual grid-based communication with clear icons • Fully customizable buttons, folders, and subfolders • Personalized organization for home and educational use • Narrated icons and sentence playback • Guided sentence building with structured connectors • Learn and Learn+ folders for organized learning • Support for multiple languages • Designed for children, families, and educators • No ads, no tracking, child-friendly experience Verbal Spectrum focuses on simplicity, structure, and adaptability, allowing each family or educator to tailor communication to a child’s daily routines, learning environment, and individual needs.
