ABSTRACT:
A radio receiver is for receiving a transmitted signal having a message signal as a received signal to reproduce the message signal into a speech signal. The radio receiver comprises a message memory section (3) for memorizing the message signal as a memorized message signal. A reading section (5, 14, 16) reads the memorized message signal as a read-out message signal out of the message memory section in response to a reproduction command to reproduce the read-out message signal into the speech signal in accordance with a reproduction speed. A counter circuit (9) counts the reproduction command to produce a count signal representative of a count. A speed controller (10) varies the reproduction speed into a varied reproduction speed in accordance with the count signal. The speed controller controls the reading section to make the reading section reproduce the read-out message signal into the speech signal on the basis of the varied reproduction speed.
