<p>The system has a hearing aid unit for outputting a current time message as a speech signal, using an external transmitter, and a memory (6) storing the speech signal to output the message. The stored signal is continuously updated to correspond to a current time of a day using an update signal that is transmitted to the unit by the transmitter. The stored signal is output to a user as the message using an output converter.</p> |
