1. Overview​

Purpose​

This document describes the architecture of a client–cloud text-to-speech system. It outlines the system's primary components, their responsibilities, and how they interact.

System Summary​

Users submit text through a client application. The request is authenticated and validated by a cloud service, executed by internal processing components, and returned incrementally for local playback.

Scope​

The system is organized into four primary components:

  • Client Application - user interaction, message lifecycle management, and local audio playback
  • Cloud Service - authentication, request validation, and job orchestration
  • Cloud Execution Workers - perform cloud-based speech synthesis via external providers
  • Web Portal (Identity & Account Services) - web-based authentication and account management

This overview focuses on architectural structure and interaction boundaries. It does not describe infrastructure configuration or provider-specific implementation details.
