PURPOSE: To make it possible to correct a sentence in a using state without exchanging a voice data memory by successively shifting succeeding data closer and always collecting unrecorded parts in a final part at the time of deleting registered voice data.

CONSTITUTION: In the case of deleting registered voice data, a mode changing switch 11 is set up to 'delete' and a sentence number switch 12 is set up to a corresponding position. When an operation setting switch 13 is turned on, an operation part 10 commands an operation part 14 to control a broadcasting sentence register 20. The register 20 correspondingly stores the sentence number of data stored in a voice data memory 19 and a storage area address in the memory 19. When the operation part 10 specifies a sentence to be deleted, the memory 19 makes the specified part blank. The operation part 14 moves up succeeding sentences through a buffer memory 14a and collects deleted addresses to the final part of the memory 19. Consequently the register 20 can store the corrected sentence and execute continuous broadcasting.
