ABSTRACT:
A telecommunications device adapted to be positioned between the sending telephone and the line connection thereof or attachable with respect to a sending telephone by way of an audio coupling wherein the DTMF (Digital Tone Multiple Frequency) keypad of the Touch-Tone telephone is utilized to spell words on a visual display device of the communications device which can be used in combination with a packet network telecommunications system having access nodes with word guessing capability wherein the word is spelled letter-by-letter and is compared against a dictionary of words having the DTMF keypad code. The code is displayed on the screen initially with the word then being telecommunicated to a remote electronic database dictionary which guesses the most frequently used word and displays it on the display screen of the hand held device. The so-chosen word can be indicated as a positive match wherein it is stored for transmission or as a negative match wherein the next most frequently used word matching that DTMF keypad code is provided by the remote electronic dictionary for display on the visual display screen. A message is created in this fashion word-by-word and is then transmitted through a telephone line interface to a remotely located receiving location wherein reception can be in any conventional manner or can be through another similarly positioned hand held communication device associated with a receiving telephone.
