Voice to Report
Overview
Field workers prefer talking over typing. This skill converts voice recordings into structured construction reports using speech-to-text and LLM processing.
Why Voice?
| Typing | Voice |
|---|
| Slow on mobile | 3x faster |
| Requires attention | Hands-free |
| Limited in cold/rain | Works anywhere |
| Formal language | Natural expression |
| Short messages | Detailed descriptions |
