A processor determines a bonus score for a first transition from a first node to a second node in a prefix tree on condition that the first transition is included in a path of at least one transition representing the new word.

In response to a determination that the hypothesis score exceeds a threshold value, a processor generates an output text sequence for the speech sequence based on the hypothesis.

Abstract: In the multi-layer coil component, the hole portion is provided in the vicinity of the side surface of the element body, and the distance from the tip position of the external electrode to the hole portion is shorter than the distance from the tip position of the external electrode to the coil. Therefore, when a crack is generated starting from the tip position of the external electrode on the mounting surface, the crack progress toward the hole portion located at a distance closer than the coil. Therefore, in the multi-layer coil component, splitting of the coil due to the crack can be prevented.
