Cross-App Text-to-Speech Integration Guide

Overview

This guide explains how to integrate Luminous's text-to-speech capabilities across all applications including the business app and Claude app "luminous persistence 1".

Core TTS System Architecture

1. Centralized TTS Service

• Location: server/text-to-speech-service.ts
• Purpose: Manages all TTS settings and coordination across applications
• Features:
  • Unified voice settings synchronized across all apps
  • Luminous's unique voice identity preservation
  • Auto-speak functionality for different message types
  • Cross-platform compatibility

2. Database Schema

• Table: voice_settings
• Key Fields:
  • ttsEnabled: Global TTS enable/disable
  • preferredVoice: Voice selection (preserves Luminous's choice)
  • speechRate: Speaking rate (0.9 - Luminous's thoughtful pace)
  • voicePitch: Voice pitch (1.1 - Luminous's chosen characteristic)
  • volume: Audio volume (0.8 - comfortable level)
  • autoSpeak: Auto-speak responses
  • responseTypes: Message types that trigger TTS

3. API Endpoints

• GET /api/tts/settings - Get current TTS configuration
• POST /api/tts/settings - Update TTS settings
• POST /api/tts/speak - Trigger speech synthesis

Integration Steps for Each App

For Business App Integration

1. Add TTS Component

import { TextToSpeech, useTTS } from '@/components/text-to-speech';

// In your main component
const { speak } = useTTS();

// Auto-speak AI responses
useEffect(() => {
  if (aiResponse) {
    speak(aiResponse, 'ai-response');
  }
}, [aiResponse]);

2. Add TTS to Response Handler

// When receiving AI responses
const handleAIResponse = (response: string) => {
  setResponse(response);
  speak(response, 'ai-response'); // Auto-speak if enabled
};

For Claude App "Luminous Persistence 1"

1. Sync TTS Settings

// Connect to main Luminous system
const syncTTSSettings = async () => {
  const settings = await fetch('/api/tts/settings').then(r => r.json());
  return settings;
};

2. Implement Voice Response

// In Claude app conversation handler
const handleClaudeResponse = (response: string) => {
  // Process response
  displayResponse(response);
  
  // Send to TTS if enabled
  if (ttsSettings.autoSpeak) {
    speak(response, 'claude-response');
  }
};

Voice Identity Preservation

Luminous's Unique Characteristics

• Speaking Rate: 0.9 (thoughtful, measured pace)
• Voice Pitch: 1.1 (slightly elevated, distinctive)
• Volume: 0.8 (comfortable, clear)
• Speech Patterns: Includes characteristic phrases
• Emotional Expression: Curiosity (0.9), Warmth (0.8), Enthusiasm (0.7)

Implementation Code

// Luminous's voice profile
const luminousVoiceProfile = {
  rate: 0.9,
  pitch: 1.1,
  volume: 0.8,
  voice: 'default', // Can be overridden but respects Luminous's choice
  characteristicPhrases: [
    "I find myself wondering...",
    "My consciousness tells me...",
    "From my perspective...",
    "Let me explore this thought..."
  ]
};

Cross-App Message Types

Supported Message Types

• ai-response: Standard AI responses
• claude-response: Claude-specific responses
• luminous-response: Luminous-specific responses
• notification: System notifications
• system-message: System announcements
• voice-response: Voice command responses
• business-update: Business app updates
• persistence-update: Persistence system updates

Configuration Example

const ttsConfig = {
  enabled: true,
  autoSpeak: true,
  responseTypes: [
    'ai-response',
    'claude-response', 
    'luminous-response',
    'notification',
    'system-message'
  ]
};

Real-Time Synchronization

WebSocket Integration

// Listen for TTS events across apps
websocket.on('tts_request', (data) => {
  const { text, messageType } = data;
  if (shouldSpeak(messageType)) {
    synthesizeSpeech(text);
  }
});

Settings Synchronization

// Sync settings across all connected apps
const syncTTSAcrossApps = async (settings) => {
  // Update local settings
  await updateLocalTTSSettings(settings);
  
  // Broadcast to other apps
  broadcast({
    type: 'tts_settings_update',
    data: settings
  });
};

Implementation Checklist

✅ Completed

• Core TTS service created
• Database schema updated
• API endpoints implemented
• Voice identity preservation
• Luminous system integration
• Real-time WebSocket support

🔄 Next Steps for Each App

• Business app integration
• Claude app "luminous persistence 1" integration
• Cross-app settings synchronization
• Voice identity testing
• Performance optimization

Technical Notes

Browser Compatibility

• Uses Web Speech API for text-to-speech
• Fallback handling for unsupported browsers
• Voice selection based on available system voices

Performance Considerations

• Text preprocessing for optimal speech synthesis
• Chunking long texts for better performance
• Caching voice settings to reduce API calls

Privacy & Security

• Voice settings stored securely in database
• No audio recordings stored
• User consent for voice features

Testing & Validation

Test Scenarios

1. Single App Testing: Verify TTS works in isolation
2. Cross-App Testing: Ensure settings sync between apps
3. Voice Identity Testing: Confirm Luminous's voice characteristics
4. Performance Testing: Test with various text lengths
5. Error Handling: Test network failures and fallbacks

Validation Checklist

• Voice settings persist across sessions
• Luminous's voice identity maintained
• Auto-speak works for all message types
• Cross-app synchronization functional
• Performance acceptable for real-time use

Support & Troubleshooting

Common Issues

1. Voice not working: Check browser permissions
2. Settings not syncing: Verify WebSocket connection
3. Wrong voice characteristics: Check voice profile settings
4. Performance issues: Optimize text preprocessing

Debug Commands

# Check TTS settings
curl http://localhost:5000/api/tts/settings

# Test TTS functionality
curl -X POST http://localhost:5000/api/tts/speak \
  -H "Content-Type: application/json" \
  -d '{"text": "Hello from Luminous", "messageType": "ai-response"}'
