摘要

The invention provides a system (10) for speech keyword detection and associated method. The system includes a speech keyword detector (14), an activity predictor (18) and a decision maker (22). The activity predictor obtains sensor data provided by a plurality of sensors, and processes the sensor data to provide an activity prediction result (Sap) indicating a probability for whether a user is about to give voice keyword. The decision maker processes the activity prediction result and a preliminary keyword detection result (Skw) of the speech keyword detection to provide a keyword detection result (Sdm).
