Wake Word Detection
A keyword-triggering technology used in voice assistants that activates a voice interaction system upon detecting a specific wake word, such as 'Hey Siri'. It serves as the primary entry point for human-machine voice interaction.
Core Facts
Timeline (last 90 days)
Wake word detection is an always-on task in edge audio processing, typically using a small deep neural network (on the order of 100,000 parameters) together with a ring buffer to complete keyword detection locally, uploading to the cloud for full inference only after a trigger.

The new generation of voice interaction has shifted to an end-to-end multimodal model architecture that understands and generates directly at the speech signal level, compressing latency and preserving paralinguistic information.
