High agreement — the answer is well-supported across models.
As an AI expert, I've analyzed the requirements for Sophia NLU, a hypothetical on-device, low-compute, no-internet voice assistant for Home Assistant, and consolidated the best approaches. The core goal is a fully-on-device voice assistant that runs on low-power hardware, is offline-capable, and responsive for everyday home automation. This hinges on prioritizing privacy, operating within compute constraints, achieving low latency, and ensuring modularity.
1. Core Principles & Why On-Device Matters
For Sophia NLU, the following principles are critical:
- ·Privacy-first: All audio, transcripts, and user models remain on the device, with no data egress to the cloud. This is a non-negotiable for users concerned about data privacy.
- ·Compute-constrained: The target hardware (e.g., ARM Cortex-A53/A55, 1-2GB RAM, <5W power budget) necessitates the use of tiny models (≤30M parameters) and aggressive quantization.
- ·Latency-critical: Voice interactions must feel
