## Device STT vs Cloud STT: Why We Use Both for Children's Speech Recognition
Amal and Thurayya use a dual speech recognition architecture: on-device STT for instant, zero-latency feedback while the child speaks, and Google Cloud Speech-to-Text for higher-accuracy pronunciation scoring after the child finishes. This hybrid approach gives children the immediate responsiveness they need to stay engaged while ensuring accuracy for meaningful learning.
### The Fundamental Tradeoff
| Metric | Device STT | Cloud STT | Need Both |
|--------|-----------|-----------|----------|
| Latency | ~100ms | ~500ms | Instant feedback + accuracy |
| Accuracy | 70% | 92% | Confidence scoring |
| Offline | ✓ | ✗ | Resilience |
| Diacritic awareness | Limited | High (with context) | Full Arabic support |
| Pronunciation detail | Coarse | Word-level timestamps | Speech marks for animation |
**The child needs both simultaneously**:
- Instant feedback keeps them engaged (device STT)
- Accurate feedback ensu
