A communication apparatus includes a registration unit for registering setting data specifying a type of email message to be read, a synthetic-speech output unit for outputting resulting speech information, and a determining unit for determining which email message to read based on the setting data. If the user stops speech output, the user can register setting data to reject reading similar email messages and reject distribution of similar email messages by simple operations. If the user does not stop speech output, the user can register setting data to read similar email messages and to cancel rejection to distribute similar email messages by simple operations.
