METHOD AND APPARATUS FOR DETECTING A TARGET KEYWORD

摘要

A method of detecting a target keyword for activating a function in an electronic device is disclosed. The method includes receiving an input sound starting from one of the plurality of portions of the target keyword. The input sound may be periodically received based on a duty cycle. The method extracts a plurality of sound features from the input sound, and obtains state information on a plurality of states associated with the portions of the target keyword. Based on the extracted sound features and the state information, the input sound may be detected as the target keyword. The plurality of states includes a predetermined number of entry states indicative of a predetermined number of the plurality of portions.

1. A method for detecting a target keyword, the target keyword including an initial portion and a plurality of subsequent portions, the method comprising:
receiving, at an electronic device, an input sound that starts from one of the subsequent portions of the target keyword; extracting sound features from the input sound; obtaining data descriptive of a state network, wherein the state network includes a single starting state, multiple entry states, and transitions from the single starting state to each of the multiple entry states; and determining whether the input sound corresponds to the target keyword based on the extracted sound features and the state network.
