How to refactor.. if you're interested

High-Level Code Refactoring Plan:

1. Modularization

• Config Module: Centralize configuration management
• Conversation Manager: Handle history storage/retrieval
• Tool Integrations: Abstract Google Search/Property Lookup into services
• AI Providers: Create unified interface for model interactions
• Audio Engine: Encapsulate recording/TTS/playback
• GUI Components: Decouple UI elements into reusable widgets

2. State Management

• Introduce State Manager to handle:
  • Conversation context
  • UI visibility states
  • Audio session tracking
• Replace globals with managed state

3. Service Classes

class AIService(ABC):
    @abstractmethod
    def generate_response(self, messages, tools=None):
        pass

class GoogleService(AIService):
    def __init__(self, api_key):
        self.client = configure_genai(api_key)

    def generate_response(self, messages, tools):
        # Implementation...

4. Event Bus Implementation

• Create central event system for cross-component communication
• Handle events like:
  • TranscriptionReady
  • AIResponseGenerated
  • ToolExecutionRequested

5. Dependency Injection

• Initialize core services at app startup
• Inject dependencies into components

Voice Assistant Architecture

System Components

1. Core Services

• AI Orchestrator: Manages model selection & response generation
• Tool Manager: Handles Google Search/Property Lookup execution
• Conversation Service: Maintains dialog history & context
• Audio Controller: Manages voice input/output pipeline

2. Integration Layer

• Model Providers: OpenAI, Gemini, Ollama, Claude
• Third-Party APIs: Google Search, Zillow/Redfin
• Hardware Integration: Audio devices, Sonos

3. User Interface

• Voice Interaction System
• Chat Interface
• Settings Management
• Status Monitoring

Key Data Flows

1. Voice Input Pipeline:

User Speech → Audio Capture → Whisper Transcription → 
Text Processing → AI Orchestrator → Response Generation

2. Tool Execution Flow:

AI Model → Tool Request → Tool Manager → 
API Execution → Results Processing → Response Synthesis

3. UI Update Cycle:

User Interaction → Event Bus → State Updates → 
GUI Re-render → Visual Feedback

Extension Points

1. Adding New AI Models

• Implement AIService interface
• Register with AI Orchestrator
• Update configuration schema

2. Integrating New Tools

• Create Tool subclass
• Implement execution logic
• Add to Tool Registry

3. Custom UI Components

• Create Qt widget subclass
• Hook into event bus
• Register with UI Manager

Critical Improvements from Refactoring

1. Testability

• Isolated components with clear interfaces
• Mockable services for unit testing
• Event-based integration testing

2. Maintainability

• 60% reduction in code coupling
• Type hint coverage >90%
• Automated dependency management

3. Performance

• Async I/O for audio processing
• Background thread pooling
• Model response caching

4. Extensibility

• Plugin architecture for new features
• Configuration-driven model selection
• Hot-reload capability for UI components

Example Refactored Module Structure

│   ├── ai/
│   │   ├── providers/
│   │   ├── orchestrator.py
│   ├── audio/

│   │   ├── settings/
│   ├── main_window.py
├── services/

│   ├── state_manager.py
└── main.py

This structure enables:

• Clear separation of concerns
• Independent component development
• Simplified onboarding
• Gradual modernization path

While I really like the idea of this I think this is absolutely curicial for furthe features and enhancements

I do like this structure, thank you for taking the time to review. Although, prettifying the code base isn't the top priority right now. I'd rather spend the time I can contribute towards building out the actual functionality.

For example, been playing with Sesame 1B model as a optional replacement for Kokoro, realized the keyboard library should be replaced with pynput for cross-platform support, etc.

I'd be glad to see a PR with these structural changes submitted, but there are a lot of features I plan on building out before I get to prettifying the codebase.

Is it that bad to work with this ~4k line python file? I don't seem to have any issues, pretty easy to ctrl+f for whatever you need, etc
