Claim Text:
1. An apparatus for supporting reading of a document, comprising: a memory that stores computer executable units; processing circuitry that executes the computer executable units stored in the memory; a model storage unit, executed by the processing circuitry, that stores a model which has been trained with a correspondence relationship between a first feature vector and an utterance style, the first feature vector being extracted from a plurality of sentences adjacent in a training document; a document acquisition unit, executed by the processing circuitry, that acquires a document to be read; a feature information extraction unit, executed by the processing circuitry, that extracts a feature information including a part of speech, a sentence type and a grammatical information from each sentence in the document to be read, and to convert the feature information to a second feature vector of each sentence; and an utterance style estimation unit, executed by the processing circuitry, that generates a connected feature vector of an estimation target sentence in the document to be read by connecting the second feature vector of the estimation target sentence with (i) a respective second feature of one sentence adjacent to and before the estimation target sentence and (ii) a respective second feature of one sentence adjacent to and after the estimation target sentence in the document to be read, to compare the connected feature vector with the first feature vector of the model, and to estimate an utterance style of the estimation target sentence based on the comparison.
