PURPOSE:To perform the collation and proofreading of a document by a document and visual information by reading character data as a unit in sequence according to the constitution of the document from a data file stored with character data of the input document, and then by outputting signals assigning position of the document. CONSTITUTION:From data file 20 stored with character data of input original document 1, character data, units, are read out in sequence according to the constitution of document 1 and then supplied to data separator 30. One data separated by this separator 30 is applied to voice generating unit 40, where voice ROM41 stored previously with a group of unit characters in the form of time-series frequency components and voice-change signal converter 42 converting the output of ROM41 into an audio signal convert the input into an audio signal and speaker 43 outputs the document by voice; and the other data from separator 30 is applied to display unit 50 and decoded by decoder 51 before being displayed by digital display unit 52, so that the collation and proofreading of the document will be attained by display and voice.
