+# 2026-05-12: VoiceCommand Module Consolidation
+
+## Summary
+
+Consolidated scattered voice command logic into a single deep module (`src/core/voiceCommand/`).
+
+## Changes
+
+### New Files
+
+- `src/core/voiceCommand/types.ts` - Centralized type definitions
+- `src/core/voiceCommand/parser.ts` - Pure parsing logic (moved from voiceCommandProcessor.ts)
+- `src/core/voiceCommand/presetActions.ts` - PresetActionRunner class (extracted from ASRService)
+- `src/core/voiceCommand/executor.ts` - VoiceCommandExecutor (the deep module)
+- `src/core/voiceCommand/index.ts` - Public exports
+
+### Modified Files
+
+- `src/core/audio/audioService.ts` - Uses VoiceCommandExecutor instead of processVoiceCommand
+- `src/hooks/useVoiceCommandHandler.ts` - Uses VoiceCommandExecutor
+- `src/__tests__/useAdvancedDigitalHumanController.test.tsx` - Added useTTS mock
+
+### Deprecated Files
+
+- `src/core/audio/voiceCommandProcessor.ts` - Marked as deprecated
+- `src/lib/voiceCommands.ts` - Marked as deprecated
+
+## Benefits
+
+1. **Locality** - Voice command logic concentrated in one module
+2. **Leverage** - Single interface for all voice command handling
+3. **Testability** - VoiceCommandExecutor can be tested through its interface
+4. **Clarity** - No more 3 different command routing systems
+
+## Migration Guide
+
+Replace:
+
+```typescript
+import { processVoiceCommand } from './voiceCommandProcessor';
+```
+
+With:
+
+```typescript
+import { VoiceCommandExecutor } from '@/core/voiceCommand';
+const executor = new VoiceCommandExecutor({ systemControls, avatarControls, onUnhandled });
+executor.execute(text);
+```
