AAC Communication Board

MeroSwar uses a research-aligned AAC (Augmentative and Alternative Communication) structure with colour-coded categories, core vocabulary prioritised, and large touch targets (minimum 56 px) for children with motor differences.

  • 500+ picture communication cards in Nepali and English
  • Core word categories: Core Words, Feelings, Needs, Food, Activities, Hygiene, Home, School, Nature, Weather
  • Sentence builder bar — tap multiple cards to form phrases
  • Emergency phrases always accessible regardless of category
  • Favourite cards for quick access to frequently used phrases
◌ Communication first

Offline-First, Always Available

After one online visit, MeroSwar caches all cards, audio, and images to the device. Communication stays available in classrooms, therapy rooms, vehicles, and areas with no connectivity.

  • Full offline operation via service worker (PWA standard)
  • Content sync runs silently in the background when online
  • New cards from the company reach every device automatically
  • Works on any Android Chrome browser — no app store needed
  • Designed for low-end Android tablets starting from Android 8
⌁ Truly offline

Customizable Voice Persona & Pace

Every child's voice should feel like their own. MeroSwar connects directly to your device's built-in speech engine, allowing communicators and families to select their preferred voice persona, adjust speed for auditory processing, and tune voice pitch — 100% offline.

  • Selectable voice personas from your iPad or Android system voices
  • Pace slider (0.70x to 1.10x) for children needing extra auditory processing time
  • Voice pitch tuning (higher or deeper) to match child or adult identity
  • Hands-Free Auto-Dismiss: Cards enlarge for visual focus and return to the board automatically after speaking
  • All voices run locally on device with zero cloud lag and zero per-word costs
🎙 Personalized voice

Sensory-Safe Design & Crisis Care

Every visual and acoustic decision was made with autistic children's sensory needs in mind — calm pastel tones, dark sensory mode, and trauma-informed crisis chimes instead of alarming sirens.

  • Calm pastel palette with high-contrast text (WCAG AA compliant)
  • Sensory Calm Dark Mode for light-sensitive communicators
  • Gentle Emergency SOS Chime: Warm harmonic chime replaces jarring sawtooth sirens
  • Static, peaceful interface with zero looping peripheral bounce distractions
  • Baloo 2 font — designed for high legibility and visual clarity
🧘 Sensory-safe

Assistive Switch & Motor Accessibility

Built for communicators with fine-motor differences, apraxia, or physical disabilities who use external assistive controllers, wheelchairs, or keyboards.

  • Physical switch access support via universal Space and Enter activation
  • High-contrast visual focus rings for keyboard and switch scanning
  • Generous touch targets (exceeding WCAG 56 px minimums)
  • Always-accessible Quick Chat bar for immediate pragmatic responses (Yes, No, Wait, Help)
♿ Switch ready

Privacy by Design: 100% Private Speech

An AAC device is an extension of the child's body. What your child says stays 100% on their tablet. MeroSwar never logs, uploads, or analyzes your child's spoken words on remote servers.

  • Zero spoken-word telemetry: Speech logs never leave the child's device
  • Custom cards, photos, and recordings are protected from deletion during session updates
  • Zero third-party commercial tracking SDKs, ad networks, or pixels
  • Completely offline-first architecture for permanent conversational privacy
🔒 Private speech
