Voice Recognition Device Wake-Up Arbitration

The patent introduces a coordinator device as an intermediary that manages wake-up arbitration among multiple voice recognition devices. The coordinator receives wake-up signals from all devices, determines which device should respond based on predefined arbitration rules, and notifies the selected device. This mediator mechanism resolves the conflict between allowing multiple devices to respond (for service coverage) and preventing mutual interference (for response accuracy).

The patent implements preliminary arbitration before actual response execution. All voice recognition devices that detect a wake-up signal enter a contention state where they exchange arbitration information with the coordinator. The coordinator pre-determines the winning device based on arbitration rules (such as device ID comparison, signal strength, or priority levels) before any device generates a response. This preliminary action prevents simultaneous responses and ensures only one device responds accurately.

The coordinator device acts as a central mediator that receives wake-up notifications from all devices in the area network. It applies arbitration rules to select a single responding device while notifying others to remain silent. This intermediary mechanism maintains broad user coverage (since all devices monitor for wake-up signals) while eliminating mutual interference (by ensuring only one device responds).

The patent implements preliminary anti-action by having the coordinator send notification messages to non-selected devices, instructing them not to respond. This preemptive suppression prevents potential broadcasting conflicts before they occur. The selected device is authorized to respond while others are actively prevented from interfering, thus eliminating mutual interference while maintaining the capability for broad user coverage.

The coordinator device serves as a mediator that manages the response arbitration process. It receives wake-up signals from all devices, applies arbitration rules to determine the single responding device, and coordinates the response timing. This ensures high service availability (since the system always responds to wake-up signals) while maintaining high response quality (by preventing simultaneous broadcasting that would cause interference).

The arbitration process occurs preliminarily before the actual response is generated. The coordinator determines which device should respond and notifies it in advance. This preliminary assignment ensures that when the response is executed, only one device broadcasts, eliminating interference and maintaining high response quality. The service availability is preserved because the arbitration process is rapid and ensures a response is always selected.
