Download Expressive Go and discover an Augmentative and Alternative Communication (AAC) solution designed for fluency, clarity, and inclusion. This app empowers children, families, and educators to communicate effortlessly with an intuitive, visually rich platform. The Smartest Language Engine on iOS Expressive Go moves beyond static phrase books, enabling true Spontaneous Novel Utterance Generation (SNUG) with grammar and morphology built-in. Intelligent Conjugation (Time Shift): Take control of narratives and planning. Use the new Time Button (Calendar Clock icon) to instantly shift the context of your speech. Tapping a verb in Past Tense Mode instantly produces the correct past conjugation (e.g., "I eat" → "I ate"), while Future Tense Mode sets up phrases like "will go." Automatic Pluralization: Eliminate grammatical errors automatically. When you select a number or quantifier (like "many" or "several"), the next Noun or People symbol you tap is instantly pluralized (e.g., "2 cookie" → "2 cookies"). This is essential for grammatically correct output. Perfect Articles (A vs. An): Our engine automatically corrects articles based on the following word's sound (e.g., "A hour" → "An hour"), ensuring the synthetic speech is always accurate and natural. Color Coding: The interface uses the Fitzgerald Key color standard to visually reinforce grammar. Folders and item borders are color-coded (Orange for Nouns, Green for Verbs, Yellow for People/Pronouns) to guide word selection and language development. Core Accessibility & Workflow Expressive Go is designed for fast, practical use in daily life. Touchless "Show Big": Quickly display your constructed message to a communication partner in a massive, high-contrast, scrollable text and image view. Simply Press and Hold the message window (sentence strip) to activate. Integrated Sharing: From the "Show Big" screen, tap the Share Button to send your message as both text and a high-resolution image of the symbols, ensuring the recipient understands the visual context. Ultimate Customization: Adjust Grid Size (from simple starter boards to complex communicative boards), customize Fonts (like AtlNile-Bold), and secure your configurations instantly using the built-in Lock Feature. Multimodal Input: Supports both Symbol Tapping and direct Typing with automatic speech feedback (speak-per-word/letter settings). Download Expressive Go today and experience the next level of intuitive, grammatically smart AAC.
