Abstract: A processor-implemented method with keyword detection includes: receiving at least a portion of a voice signal input by a user; extracting a voice feature of the voice signal; inputting an abstract representation sequence of a preset keyword and the voice feature to an end-to-end keyword detection model, and determining a result on whether the preset keyword is present in the voice signal output from the keyword detection model, wherein the keyword detection model predicts whether the preset keyword is present in the voice signal by: determining an abstract representation sequence of the voice signal, based on the voice feature and the abstract representation sequence of the preset keyword; predicting position information of the preset keyword in the voice signal based on the abstract representation sequence of the voice signal; and predicting whether the preset keyword is present in the voice signal, based on the abstract representation sequence of the voice signal and the position information.
