An electronic mail server, computer-readable medium and method of delivering an electronic message to a wireless communication device are provided. An electronic text message for delivery to a wireless communication device is received. When the wireless communication device is determined to be in an audio message mode, an audio message comprising speech generated from the received electronic text message is delivered to the wireless communication device. The wireless communication device may be determined to be in an audio message when an audio message filter parameter received from the wireless communication device corresponds to the electronic text message. The audio message filter parameter may be based upon a sender's identity. The electronic text message is converted to the audio message by sending a conversion request for the electronic text message to a text-to-speech conversion server and receiving the audio message from the text-to-speech server.
