Method of and means for accessing computerized data bases utilizing a touch-tone telephone instrument
First Claim
1. The method of utilizing a telephone instrument having transmitter and receiver components, and further including a touch pad having individually depressable alpha-numeric keys each representing a single number and a plurality of letters of the alphabet, to obtain a desired piece of information as a response to an inquiry generated at the situs of the instrument, that comprises the steps of:
- (a) spelling out one of more words by a single depression, for each letter in a work, of only that key, and no others, that represents said letter;
(b) transmitting the alphabetically ordered inquiry, encoded as a numeric string, from the transmitter component of the instrument to a computer means;
(c) at the computer means, decoding the numeric string by selecting which of the several alphabetic characters represented by each depressed key will combine with similarly selected characters of the other depressed keys to form the spelled work or words, including the following sequence;
(1) responsive to the depression of the first and second numeric keys used, selecting only a letter or letters among those represented by the first key, and only a letter or letters among those represented by the second key, that can be validly combined as a first-and-second-letter pairing in the formation of a word, while rejecting all other letter combinations that cannot be so paired,(2) responsive to the depression of the third key used, selecting only a letter or letters that can be combined with the selected letter(s) represented by the second key as a second-and-third-letter pairing in the formation of a word or words, while rejecting all other letter combinations that cannot be so paired, and(3) continuing in like manner through the numeric string to determine similarly acceptable consecutive letter pairings;
(d) matching the numeric string as decoded at the computer means with a piece of information that has been previously stored therein and is to be transmitted to the telephone instrument; and
(e) synthesizing said piece of information in voice form and transmitting it to the receiver of the instrument.

Abstract
A conventional Touch-Tone telephone instrument is rendered functional in the same manner and to the same extent as a computer terminal having alpha-numeric capability, as regards transmission of queries directed to computerized data bases. It is also rendered functional as a recipient of information transmitted from the data base through a telephone network to provide intelligence heretofore made available only on the video screen of the computer terminal, or through automatic printers. Disclosed is the substitution of the instrument for a computer terminal and its associated video screen or teleprinter, without requirement of modification of the instrument, so that a subscriber gains from the use of the telephone functions heretofore obtainable only by providing oneself with a computer terminal and its associated screen and/or automatic printer. The user spells out one or more words by depressing the conventional, alpha-numerically marked keys of a Touch-Tone telephone instrument. A computer to which the telephone is connected by a telephone network decodes the numeric sequence represented by depressing keys needed to spell out the selected word or words. The computer then provides an oral response transmitted through the telephone receiver to the caller, as audible intelligence.

8. The method of utilizing a telephone instrument having transmitter circuitry and a receiver, said instrument being of the touch-pad type having keys at least some of which are alpha-numeric and bear representations of a single number and an associated plurality of letters, to obtain a desired piece of information as a response to an inquiry generated at the situs of the instrument, that comprises the steps of:
-
(a) spelling out at least one word by momentarily depressing the keys bearing the letters of said word, once and only once for each letter of the word or words being spelled, in the order in which said letters appear in the spelled word, to form a string of letters encoded in numeric form in which each number in the string can represent any of the plurality of letters found on the same key as that number, and in which the encoded word represents an inquiry; (b) transmitting said encoded string to a computer means; (c) utilizing the computer means to compare the order in which the numbers appear in said string to select those letters associated with the respective numbers that will form the word spelled out by depression of the alpha-numeric keys and enter it in the computer means as a complete inquiry, including the following sequence; (1) responsive to the depression of the first and second numeric keys used, selecting only a letter or letters among those represented by the first key, and only a letter or letters among those represented by the second key, that can be validly combined as a first-and-second-letter Pairing in the formation of a word, while rejecting all other letter combinations that cannot be so paired, (2) responsive to the depression of the third key used, selecting only a letter or letters that can be combined with the selected letter(s) represented by the second key as a second-and-third letter pairing in the formation of a word or words, while rejecting all other letter combinations that cannot be so paired, and (3) continuing in like manner through the numeric string to determine similarly acceptable consecutive letter pairings; (d) matching up, within the computer means, a string of pulses that together from a correct response to the inquiry; (e) synthesizing the response string of pulses to voice form; and (f) transmitting the synthesized voice form to the receiver of the telephone to provide the user with an intelligible audio response to the inquiry. - View Dependent Claims (9, 10, 11)

12. The method of utilizing a telephone instrument, of a type that will enter a transmitting mode by depressing alphanumeric keys each of which represents one single-digit number and a plurality of letters of the alphabet, said instrument having transmitting circuitry and an audio receiver in which the transmitting component substitutes for a computer terminal in the sense of transmitting an encoded inquiry and the receiver substitutes for a display screen and printer in the sense of providing a response to the inquiry, that includes the steps of:
-
(a) spelling out one or more words by a single depression, for each letter in a word, of only that key, and no others, that represents said letter; (b) transmitting the alphabetically ordered inquiry encoded as a numeric string to an access processor; (c) at the access processor, decoding the numeric string by selecting which of the several alphabetic characters represented by each depressed key will combine with similarly selected characters of the other depressed keys to form the spelled word or words, including the following sequence; (1) responsive to the depression of the first and second numeric keys used, selecting only a letter or letters among those represented by the first key, and only a letter or letters among those represented by the second key, that can be validly combined as a first-and-second-letter pairing in the formation of a word, while rejecting all other letter combinations that cannot be so paired, (2) responsive to the depression of the third key used, selecting only a letter or letters that can be combined with the selected letter(s) represented by the second key as a second-and-third letter pairing in the formation of a word or words, while rejecting all other letter combinations that cannot be so paired, and (3) continuing in like manner through the numeric string to determine similarly acceptable consecutive letter pairings; (d) determining if the numeric string, as decoded at the access processor is subject to match-up with any one response selectable from a memory bank of preformulated reponses stored at the access processor; (e) if a response can be provided by the access processor, voice-synthesizing the response and transmitting the same to the inquirer via the audio receiver; (f) if a response cannot be formulated by the access processor, transmitting the inquiry to a data base computer for formulation of a response; (g) in the event that the response is formulated by the data base computer, transmitting the response of the data base computer to the access processor; and (h) at the access processor, voice-synthesizing the response of the data base computer for transmission to the caller via the audio receiver.
