To change a presenting order of a sentence when presenting each sentence of writing.

In this presenting device for presenting the sentence of writing in an interactive format, when an operation command is inputted from an input device, it is determined whether the operation command stores a command to instruct the next document (154). In the case of a command to instruct the next document, processing for shifting to the next document is carried out (164). In the case of a command for an operation instruction other than the command to instruct the next document, a text corresponding to this command is retrieved and processing is performed so that the text can be presented (156).
