Abstract
A keyword detection method, apparatus, electronic device, and storage medium, the method including: determining, for a target audio segment in a target audio, a first probability that a target audio frame in the target audio segment corresponds to a target character unit, the target character unit being a character unit included in a preset keyword, and a position of the target audio frame in the target audio segment corresponding to a position of the target character unit in the preset keyword (110); determining a second probability that the target audio segment corresponds to the preset keyword based on the first probability, the second probability representing a probability that each audio frame in the target audio segment is, in turn, each of the character units in the preset keyword (120); and determining whether the target audio segment is a voice segment of the preset keyword based on the second probability (130).
