A telecommunication system has the ability to identify words typed out on a DTMF multi-button pad, convert the words into digital format at a telephone access node and transmit that information on a packet transport network to a remote access node where the words are converted into speech and forwarded to the receiver. The sender begins by typing out the letters of the word on the DTMF buttons. As the word is typed out it is compared at an entrance telephone access node to words stored in a word data bank referred to as a word guessing dictionary. The words in the data bank are stored according to length, numeric equivalent and relative frequency. A prompter asks the sender if the identified word is correct. If it is correct, it is converted into ASCII digital format and transmitted by packet transport network to an egress telephone access node near the receiver. A voice synthesizer then converts the ASCII digital information back into speech so that the receiver can listen to the message typed on the DTMF buttons by the sender.
