How Siri Understands You on iPhone
Siri uses a combination of on-device neural networks and cloud-based language models to interpret what you say. On iPhone, this design helps keep common requests fast while still handling complex queries with context.
When you speak, your iPhone converts speech to text, detects intent, and matches it to functions, apps, or services. The system balances local processing for privacy with cloud resources for richer understanding and third‑party integrations.
