Add voice intent classification for hands-free tracking
Implemented comprehensive voice command understanding system: **Intent Classification:** - Feeding intent (bottle, breastfeeding, solid food) - Sleep intent (naps, nighttime sleep) - Diaper intent (wet, dirty, both, dry) - Unknown intent handling **Entity Extraction:** - Amounts with units (ml, oz, tbsp): "120 ml", "4 ounces" - Durations in minutes: "15 minutes", "for 20 mins" - Time expressions: "at 3:30 pm", "30 minutes ago", "just now" - Breast feeding side: "left", "right", "both" - Diaper types: "wet", "dirty", "both" - Sleep types: "nap", "night" **Structured Data Output:** - FeedingData: type, amount, unit, duration, side, timestamps - SleepData: type, duration, start/end times - DiaperData: type, timestamp - Ready for direct activity creation **Pattern Matching:** - 15+ feeding patterns (bottle, breast, solid) - 8+ sleep patterns (nap, sleep, woke up) - 8+ diaper patterns (wet, dirty, bowel movement) - Robust keyword detection with variations **Confidence Scoring:** - High: >= 0.8 (strong match) - Medium: 0.5-0.79 (probable match) - Low: < 0.5 (uncertain) - Minimum threshold: 0.3 for validation **API Endpoint:** - POST /api/voice/transcribe - Classify text or audio - GET /api/voice/transcribe - Get supported commands - JSON response with intent, confidence, entities, structured data - Audio transcription placeholder (Whisper integration ready) **Implementation Files:** - lib/voice/intentClassifier.ts - Core classification (600+ lines) - app/api/voice/transcribe/route.ts - API endpoint - scripts/test-voice-intent.mjs - Test suite (25 tests) - lib/voice/README.md - Complete documentation **Test Coverage:** 25 tests, 100% pass rate ✅ Bottle feeding (3 tests) ✅ Breastfeeding (3 tests) ✅ Solid food (2 tests) ✅ Sleep tracking (6 tests) ✅ Diaper changes (7 tests) ✅ Edge cases (4 tests) **Example Commands:** - "Fed baby 120 ml" → bottle, 120ml - "Nursed on left breast for 15 minutes" → breast_left, 15min - "Changed wet and dirty diaper" → both - "Napped for 45 minutes" → nap, 45min System converts natural language to structured tracking data with high accuracy for common parenting voice commands. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# Voice Intent Classification
|
||||
|
||||
Accurate classification of voice commands for hands-free activity tracking.
|
||||
|
||||
## Overview
|
||||
|
||||
The voice intent classification system converts natural language voice commands into structured data for feeding, sleep, and diaper tracking. It uses pattern matching and entity extraction to understand user intent and extract relevant details.
|
||||
|
||||
## Supported Intents
|
||||
|
||||
### 1. Feeding
|
||||
Track bottle feeding, breastfeeding, and solid food consumption.
|
||||
|
||||
**Subtypes:**
|
||||
- `bottle` - Bottle feeding with formula or pumped milk
|
||||
- `breast_left` - Breastfeeding from left side
|
||||
- `breast_right` - Breastfeeding from right side
|
||||
- `breast_both` - Breastfeeding from both sides
|
||||
- `solid` - Solid food or meals
|
||||
|
||||
**Extractable Entities:**
|
||||
- Amount (ml, oz, tbsp)
|
||||
- Duration (minutes)
|
||||
- Side (left, right, both)
|
||||
- Time (absolute or relative)
|
||||
|
||||
**Examples:**
|
||||
```
|
||||
"Fed baby 120 ml"
|
||||
"Gave him 4 ounces"
|
||||
"Nursed on left breast for 15 minutes"
|
||||
"Breastfed on both sides for 20 minutes"
|
||||
"Baby ate solid food"
|
||||
"Had breakfast"
|
||||
```
|
||||
|
||||
### 2. Sleep
|
||||
Track naps and nighttime sleep.
|
||||
|
||||
**Subtypes:**
|
||||
- `nap` - Daytime nap
|
||||
- `night` - Nighttime sleep
|
||||
|
||||
**Extractable Entities:**
|
||||
- Duration (minutes)
|
||||
- Type (nap or night)
|
||||
- Time (start/end)
|
||||
|
||||
**Examples:**
|
||||
```
|
||||
"Baby fell asleep for a nap"
|
||||
"Napped for 45 minutes"
|
||||
"Put baby down for bedtime"
|
||||
"Baby is sleeping through the night"
|
||||
"Baby woke up"
|
||||
```
|
||||
|
||||
### 3. Diaper
|
||||
Track diaper changes.
|
||||
|
||||
**Subtypes:**
|
||||
- `wet` - Wet diaper (urine)
|
||||
- `dirty` - Dirty diaper (bowel movement)
|
||||
- `both` - Both wet and dirty
|
||||
- `dry` - Dry/clean diaper
|
||||
|
||||
**Extractable Entities:**
|
||||
- Type (wet, dirty, both)
|
||||
- Time (when changed)
|
||||
|
||||
**Examples:**
|
||||
```
|
||||
"Changed wet diaper"
|
||||
"Dirty diaper change"
|
||||
"Changed a wet and dirty diaper"
|
||||
"Baby had a bowel movement"
|
||||
"Diaper had both poop and pee"
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Basic Classification
|
||||
|
||||
```typescript
|
||||
import { classifyIntent } from '@/lib/voice/intentClassifier';
|
||||
|
||||
const result = classifyIntent("Fed baby 120 ml");
|
||||
|
||||
console.log(result.intent); // 'feeding'
|
||||
console.log(result.confidence); // 0.9
|
||||
console.log(result.structuredData);
|
||||
// {
|
||||
// type: 'bottle',
|
||||
// amount: 120,
|
||||
// unit: 'ml'
|
||||
// }
|
||||
```
|
||||
|
||||
### With Validation
|
||||
|
||||
```typescript
|
||||
import { classifyIntent, validateClassification } from '@/lib/voice/intentClassifier';
|
||||
|
||||
const result = classifyIntent(userInput);
|
||||
|
||||
if (validateClassification(result)) {
|
||||
// Confidence >= 0.3 and intent is known
|
||||
createActivity(result.structuredData);
|
||||
} else {
|
||||
// Low confidence or unknown intent
|
||||
showError("Could not understand command");
|
||||
}
|
||||
```
|
||||
|
||||
### Confidence Levels
|
||||
|
||||
```typescript
|
||||
import { getConfidenceLevel } from '@/lib/voice/intentClassifier';
|
||||
|
||||
const level = getConfidenceLevel(0.85); // 'high'
|
||||
// 'high': >= 0.8
|
||||
// 'medium': 0.5 - 0.79
|
||||
// 'low': < 0.5
|
||||
```
|
||||
|
||||
## API Endpoint
|
||||
|
||||
### POST /api/voice/transcribe
|
||||
|
||||
Transcribe audio or classify text input.
|
||||
|
||||
**Text Input:**
|
||||
```bash
|
||||
curl -X POST http://localhost:3030/api/voice/transcribe \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"text": "Fed baby 120ml"}'
|
||||
```
|
||||
|
||||
**Response:**
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"transcription": "Fed baby 120ml",
|
||||
"classification": {
|
||||
"intent": "feeding",
|
||||
"confidence": 0.9,
|
||||
"confidenceLevel": "high",
|
||||
"entities": [
|
||||
{
|
||||
"type": "amount",
|
||||
"value": 120,
|
||||
"confidence": 0.9,
|
||||
"text": "120 ml"
|
||||
}
|
||||
],
|
||||
"structuredData": {
|
||||
"type": "bottle",
|
||||
"amount": 120,
|
||||
"unit": "ml"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### GET /api/voice/transcribe
|
||||
|
||||
Get supported commands and examples.
|
||||
|
||||
```bash
|
||||
curl http://localhost:3030/api/voice/transcribe
|
||||
```
|
||||
|
||||
## Pattern Matching
|
||||
|
||||
The classifier uses regex patterns to detect intents:
|
||||
|
||||
### Feeding Patterns
|
||||
- Fed/feed/gave + amount + unit
|
||||
- Bottle feeding keywords
|
||||
- Breastfeeding keywords (nursed, nursing)
|
||||
- Solid food keywords (ate, breakfast, lunch, dinner)
|
||||
|
||||
### Sleep Patterns
|
||||
- Sleep/nap keywords
|
||||
- Fell asleep / woke up
|
||||
- Bedtime / night sleep
|
||||
|
||||
### Diaper Patterns
|
||||
- Diaper/nappy keywords
|
||||
- Changed diaper
|
||||
- Wet/dirty/poop/pee keywords
|
||||
- Bowel movement / BM
|
||||
|
||||
## Entity Extraction
|
||||
|
||||
### Amount Extraction
|
||||
Recognizes:
|
||||
- `120 ml`, `120ml`, `120 milliliters`
|
||||
- `4 oz`, `4oz`, `4 ounces`
|
||||
- `2 tbsp`, `2 tablespoons`
|
||||
|
||||
### Duration Extraction
|
||||
Recognizes:
|
||||
- `15 minutes`, `15 mins`, `15min`
|
||||
- `for 20 minutes`
|
||||
- `lasted 30 minutes`
|
||||
|
||||
### Time Extraction
|
||||
Recognizes:
|
||||
- Absolute: `at 3:30 pm`, `10 am`
|
||||
- Relative: `30 minutes ago`, `2 hours ago`
|
||||
- Contextual: `just now`, `a moment ago`
|
||||
|
||||
### Side Extraction (Breastfeeding)
|
||||
Recognizes:
|
||||
- `left breast`, `left side`, `left boob`
|
||||
- `right breast`, `right side`
|
||||
- `both breasts`, `both sides`
|
||||
|
||||
### Type Extraction (Diaper)
|
||||
Recognizes:
|
||||
- Wet: `wet`, `pee`, `urine`
|
||||
- Dirty: `dirty`, `poop`, `poopy`, `soiled`, `bowel movement`, `bm`
|
||||
- Combination: detects both keywords for mixed diapers
|
||||
|
||||
## Common Mishears & Corrections
|
||||
|
||||
The system handles common voice recognition errors:
|
||||
|
||||
| Heard | Meant | Handled |
|
||||
|-------|-------|---------|
|
||||
| "mils" | "ml" | ✅ Pattern includes "ml" variations |
|
||||
| "ounce says" | "ounces" | ✅ Pattern matches "ounce" or "oz" |
|
||||
| "left side" vs "left breast" | Same meaning | ✅ Both patterns recognized |
|
||||
| "poopy" vs "poop" | Same meaning | ✅ Multiple variations supported |
|
||||
|
||||
## Confidence Scoring
|
||||
|
||||
Confidence is calculated based on:
|
||||
- **Pattern matches**: More matches = higher confidence
|
||||
- **Entity extraction**: Successfully extracted entities boost confidence
|
||||
- **Ambiguity**: Conflicting signals reduce confidence
|
||||
|
||||
Minimum confidence threshold: **0.3** (30%)
|
||||
|
||||
## Testing
|
||||
|
||||
Run the test suite:
|
||||
|
||||
```bash
|
||||
node scripts/test-voice-intent.mjs
|
||||
```
|
||||
|
||||
**Test Coverage:**
|
||||
- 25 test cases
|
||||
- Feeding: 8 tests (bottle, breast, solid)
|
||||
- Sleep: 6 tests (nap, night, duration)
|
||||
- Diaper: 7 tests (wet, dirty, both)
|
||||
- Edge cases: 4 tests
|
||||
|
||||
## Multi-Language Support
|
||||
|
||||
Currently supports English only. Planned languages:
|
||||
- Spanish (es-ES)
|
||||
- French (fr-FR)
|
||||
- Portuguese (pt-BR)
|
||||
- Chinese (zh-CN)
|
||||
|
||||
Each language will have localized patterns and keywords.
|
||||
|
||||
## Integration with Whisper API
|
||||
|
||||
For audio transcription, integrate OpenAI Whisper:
|
||||
|
||||
```typescript
|
||||
import OpenAI from 'openai';
|
||||
|
||||
const openai = new OpenAI({ apiKey: process.env.OPENAI_API_KEY });
|
||||
|
||||
async function transcribeAudio(audioFile: File): Promise<string> {
|
||||
const transcription = await openai.audio.transcriptions.create({
|
||||
file: audioFile,
|
||||
model: 'whisper-1',
|
||||
language: 'en', // Optional: specify language
|
||||
});
|
||||
|
||||
return transcription.text;
|
||||
}
|
||||
```
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
- [ ] Audio transcription with Whisper API
|
||||
- [ ] Multi-language support (5 languages)
|
||||
- [ ] Context-aware classification (user history)
|
||||
- [ ] Custom vocabulary (child names, brand names)
|
||||
- [ ] Clarification prompts for ambiguous commands
|
||||
- [ ] Machine learning-based classification
|
||||
- [ ] Offline voice recognition fallback
|
||||
- [ ] Voice feedback confirmation
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
**Q: Classification returns 'unknown' for valid commands**
|
||||
- Check if keywords are in supported patterns
|
||||
- Verify minimum confidence threshold (0.3)
|
||||
- Add variations to INTENT_PATTERNS
|
||||
|
||||
**Q: Entities not extracted correctly**
|
||||
- Check regex patterns in ENTITY_PATTERNS
|
||||
- Verify unit formatting (spaces, abbreviations)
|
||||
- Test with simplified command first
|
||||
|
||||
**Q: Confidence too low despite correct intent**
|
||||
- Multiple pattern matches boost confidence
|
||||
- Add more specific patterns for common phrases
|
||||
- Adjust confidence calculation algorithm
|
||||
|
||||
## Error Codes
|
||||
|
||||
- `VOICE_INVALID_INPUT` - Missing or invalid text input
|
||||
- `VOICE_AUDIO_NOT_IMPLEMENTED` - Audio transcription not yet available
|
||||
- `VOICE_INVALID_CONTENT_TYPE` - Wrong Content-Type header
|
||||
- `VOICE_CLASSIFICATION_FAILED` - Could not classify intent
|
||||
- `VOICE_TRANSCRIPTION_FAILED` - General transcription error
