+**Integration with WakeWordContext:**

+
+---

+**6. WakeWordService** (`services/wake-word-service.ts`)

+ onWakeWordDetected: (remainingTranscript: string) => void;

+ stop(): void; // Stop listening
+ processTranscript(transcript: string): boolean; // Check for wake word
+ resetAfterDetection(): void; // Reset to listening state
+}

+
+**8. WakeWordContext** (`contexts/wake-word-context.tsx`)
+
+**Purpose:** App-wide state sharing for wake word functionality
+
+**Usage:**
+```typescript
+// In root layout

-- Toggles become functional
-- Enable/disable voice activation
-- Control wake word detection
-- Configure voice sensitivity

## Changelog
+### Version 0.5.0 - November 28, 2025 ("Hey Shoppy" Wake Word Detection)
+
+**Added:**
+- Wake word detection service for "Hey Shoppy" activation
+- Custom `useWakeWord` hook for React integration
+- `WakeWordContext` for app-wide state management
+- Settings toggle now enables/disables wake word detection
+- VoiceActivationBanner shows listening state
+- VoiceStatusIndicator reflects wake word detection status
+
+**Wake Word Feature:**
+- Users can say "Hey Shoppy" to start voice command listening
+- Works in addition to pressing the microphone button
+- Settings toggle in Voice Features section controls activation
+- Banner shows "Listening..." when actively listening for wake word
+- Green indicator when ready, red when listening
+
+**Architecture:**
+- `WakeWordService` - Core service for wake word detection
+ - Processes transcripts and detects "hey shoppy" phrase
+ - Supports enable/disable functionality
+ - Status states: idle, listening, detected
+ - Extracts command text after wake phrase
+
+- `useWakeWord` hook - React hook wrapper
+ - Manages service lifecycle
+ - Provides state: status, isListening, enabled, detectedCommand
+ - Methods: startListening, stopListening, setEnabled, processTranscript
+
+- `WakeWordProvider` - Context provider
+ - App-wide state sharing
+ - Integrated in root layout
+ - Optional onWakeWordDetected callback
+
+**Test Coverage:**
+- WakeWordService: 29 tests
+- useWakeWord hook: 16 tests
+- WakeWordContext: 14 tests
+- Settings integration: 6 tests
+- VoiceActivationBanner: 11 tests
+- Total: 194 tests, all passing
+
+**Usage:**
+```typescript
+// In any component within WakeWordProvider

+
+**Settings Screen:**
+- Voice Activation toggle now functional when context available
+- Shows "Enabled"/"Disabled" status
+- Toggle controls wake word detection globally
+
+**Next Steps:**
+- Integrate with expo-speech-recognition for actual speech-to-text
+- Connect detected commands to shopping list actions
+- Add voice feedback using text-to-speech
