Features and Requirements

This document outlines the core functionality and performance expectations for the AAC Integration API. The system provides a streamlined audio-to-text processing service that enables game modules to integrate voice-based controls from AAC devices and natural speech.

Functional Requirements​

Core Audio Processing​

  • The system accepts and records audio files through a RESTful POST endpoint supporting multiple audio formats
  • The API converts speech to text using Google's Speech Recognition, processing audio from AAC devices
  • The system returns structured data including transcription, audio metadata, request information, and error details
  • The API automatically detects audio format from file headers(WAV, FLAC, MP3, etc.) with fallback format support

Metadata and Logging​

  • The system extracts audio file metadata including duration, sample rate, file size, and format information.
  • The API implements logging, whcih records data for every audio processing attempt.
  • The API captures request context including the timestampe, browser type, and device type.
  • The API provides detailed error reporting with specific error codes and messaging for debugging and issues with audio processing

Audio and Game Processing​

  • The system enable games and external applications to connect to AAC devices through a unified API interface.
  • The API should translate user speech or selections into AAC-compatible actions or symbols.
  • The system should support real-time communication between a user’s AAC board and the connected application.
  • The API should allow developers to define or import AAC layouts (such as boards or symbol sets) used by their game or app.
  • The system should return structured feedback confirming recognized input and selected AAC elements.
  • The API should be compatible with existing AAC tools, such as CoughDrop, and designed to accommodate future integrations.

Non-Functional Requirements​

  • The API should process audio files efficiently with fast response times and for large audio files
  • It should be reliable and stable during real-time audio or symbol exchange.
  • The system should be secure, protecting user and device data from unauthorized access.
  • The API should be scalable, supporting multiple concurrent requests from different applications.
  • It should be flexible and extensible, allowing future updates to handle new AAC devices, symbol systems, or input types.
  • The system should provide clear feedback and error handling to assist both developers and users in understanding API responses.

Summary​

The AAC Integration API focuses on bridging the gap between AAC communication tools and interactive applications. By standardizing the way speech, symbols, and AAC boards connect to external systems, the project will help developers build more inclusive experiences without needing to hardcode accessibility features.
