## ElevenLabs Integration

### API Configuration

- **Endpoint:** `https://api.elevenlabs.io/v1/text-to-speech/{voice_id}`
- **Model:** `eleven_monolingual_v1` (or `eleven_turbo_v2` for faster processing)
- **Settings:**
  - `stability: 0.3` — Balanced variability for natural speech
  - `similarity_boost: 0.75` — Close voice resemblance
  - `style: 0.5` — Professional, clear delivery

### Voice Presets

```json
{
  "josh": {
    "voice_id": "pNInz6obpgDQGcFmaJgB",
    "tone": "devotional",
    "stability": 0.3,
    "similarity_boost": 0.75,
    "style": 0.5,
    "description": "Deep, calm, reverent — perfect for devotionals"
  },
  "chris": {
    "voice_id": "iP95p4xoKVk53GoZ742B",
    "tone": "teaching",
    "stability": 0.5,
    "similarity_boost": 0.75,

}
```

## Scripture Data Integration

Integrates with **scripture-curated** skill data when available:

```javascript
// Auto-pull scripture references
const scripture = await scriptureData.lookup('Romans 8:1-17');
// Returns: { text, context, commentary, themes }
```

Falls back to built-in scripture library if external data unavailable.

## Examples

### Example 1: Morning Peace Devotional

```bash
voice-devotional daily --theme peace --voice josh
```

**Output Structure:**
1. **Opening** (10s) — "Good morning. Today's devotional: Peace"
2. **Scripture** (30s) — Psalm 4:8, John 14:27
3. **Reflection** (90s) — Meditation on peace amid chaos
4. **Prayer** (60s) — Guided closing prayer

### Example 2: Weekly Hope Study Plan

```bash
voice-devotional plan --topic hope --days 7 --voice josh
```

**Generates:** 7 individual MP3s + manifest.json
- Day 1: Hope Defined (Romans 15:13)
- Day 2: Hope Through Trials (1 Peter 1:3-7)
- Day 3: Hope and Faith (Hebrews 11:1)
- Day 4: Living Hope (1 Peter 1:3)
- Day 5: Hope's Anchor (Hebrews 6:19)
- Day 6: Sharing Hope (1 Peter 3:15)
- Day 7: Hope's Fulfillment (Revelation 21:4)

### Example 3: Extended Scripture Reading

```bash
voice-devotional scripture --passage "Romans 8:1-17" --voice josh
```

**Includes:**
- Context setting (Paul's letter to Romans, historical background)
- Full passage reading with natural pacing
- Key verse callouts
- Closing reflection

## Advanced Features

### Custom Templates

Create devotionals with custom structure:

```javascript
const template = {
  opening: "Your opening message",
  scripture: ["John 3:16", "Romans 5:8"],
  reflection: "Your reflection text",
  prayer: "Closing prayer",
  music: "optional-fade-out"
};

const result = await vd.generateCustom(template, { voiceId });
```

### Batch Generation

Generate multiple devotionals:

```javascript
const themes = ['peace', 'hope', 'faith', 'love', 'strength'];
const results = await vd.generateBatch(themes, { 
  voiceId: 'josh',
  includeManifest: true 
});
```

### Background Music

Add optional ambient music under voice (low volume):

```javascript
const result = await vd.generateDaily({
  theme: 'peace',
  voiceId: 'josh',
  music: 'peaceful-piano'  // ambient, peaceful-piano, nature-sounds
});
```

## Troubleshooting

### Issue: API rate limit exceeded

**Solution:** 
- Add delay between requests: `--delay 2000`
- Batch process during off-peak hours
- Check ElevenLabs account limits

### Issue: Audio quality sounds robotic

**Solution:**
- Lower `stability` value (0.1-0.3 for more variance)
- Adjust `similarity_boost` (0.5-0.95 range)
- Try different voice: `--voice chris` or `--voice bella`

### Issue: Output file is too long

**Solution:**
- Use shorter scripture passages
- Reduce reflection length
- Remove optional sections like music/outro
