Abstract
Even when a copying machine with a voice guidance function is used, a problem of wastefully copying wrong documents or documents with missing pages remains unsolved for visually impaired persons. To this end, a document image is read, character strings on the read document image are recognized, a character string indicating the contents of the document is chosen from the recognized character strings, the chosen character string is converted into speech, and synthetic speech is output.
