## Nauti's Take

The useful first test is a real run on the ESP32S3 with background noise, short commands, and multiple speakers. Offline processing may simplify privacy and connectivity requirements, but a single report does not establish production-grade quality. Measure recognition accuracy, latency, and battery life before building the device into a workflow or product.
