  • Patent number: 6366651
    Abstract: The communication device provides the capability to automatically convert between voice and text messages. This communication device enables the calling party to input a message in voice mode, then activate the communication device to automatically convert the message into a text message format for transmission to the called party. The communication device can display the content of the text message prior to transmission or can retrieve the message from its memory and play the message back to the calling party in an audio mode. The communication device automatically initiates the outgoing call and, since the message is transmitted in a text mode to the called party, the destination can be a computer system or output to a printer. This feature therefore enables hands free operation for E-Mail.
