Portable playback devices with network operation modes

This invention describes smart headphones or earbuds that include a built-in voice assistant. The device uses microphones to capture user voice commands and plays back audio through its speakers. For understanding commands, it can process some simple keywords directly on the device, but for more complex requests, it sends the voice data over a network to a cloud-based system for interpretation.

Why it matters: Filed before the widespread adoption of highly efficient on-device AI models. The claims describe a hybrid local/cloud NLU system, and advancements in local AI now allow for more sophisticated processing directly on the device, potentially reducing latency and improving privacy.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedIntegrated electronics, voice assistant software system
