An information processing apparatus includes a memory storing instructions. The instructions cause the apparatus to extract a plurality of local features from data indicating a speech, the characteristics of feature extraction being formed through learning; and to encode a series of chronological features of the data based on the plurality of local features, characteristics of encoding the series of chronological features being formed through learning. The instructions also cause the apparatus to generate information obtained by weighting features at a specific point in time associated with emotion classification, of the series of chronological features encoded, characteristics of weighting the features at the specific point in time being formed through learning; and to classify emotion corresponding to the data using the information obtained by weighting the features at the specific point in time, characteristics of classification being formed through learning.
