TtsManager class

TtsManager - Text-to-Speech (TTS) handler

Encapsulates all logic related to voice synthesis using FlutterTts. This class is designed to be developer-controlled, meaning:

  • No user-selectable voice menu
  • Predefined voice and language settings per game

Key Responsibilities:

  • Initialize and configure the TTS engine
  • Speak text aloud with configured pitch, speed, volume
  • Handle completion and cancellation callbacks
  • Expose speaking status via isSpeaking

Usage Example:

final tts = TtsManager();
await tts.initialize(language: 'en-US');
await tts.speak("Welcome to the dungeon.");
