abstract = "Speech synthesis, the production of intelligible speech from computer data, is
no longer a novelty. Text-to-speech products with unlimted vocabulary are
available. Soon, these products will be incorporated into telephone based
inquiry systems that will give users access to data-bases from any phone. These
systems would enable ordinary telephone sets to function as limited computer
terminals. To accomplish this, in addition to the ability of sending
information to the user in the form of computer generated speech, the system
should be capable of accepting the data transmitted by the telephone (entries
on the keypad of a Touch-Tone telephone set).
The aim of this project has been to study possible approaches leading to
implementation of a system that would enable a computer to fully use an
ordinary telephone set. The six major functions associated with using the phone
are:
1. Picking-up the receiver
2. Dialing a number
3. Talking (transmitting information)
4. Listening (receiving information)
5. Hanging-up
6. Recognizing the ring.
Lifting and replacing the receiver is accomplished by using a solenoid that
mechanically controls the cradle switch. Dialing is implemented by generating
DTMF signals on the voice channel. A Votrax SC-01 phoneme synthesizer enables
the system to talk. A MSD 3201 CMOS DTMF decoder/receiver can provide the
ability to accept information (listen). Ring recognition may be accomplished
through the use of a sound switch.
By using the above mentioned functions, a computer could allow for the use of
an ordinary telephone set as a limited terminal. Although not in the form of a
%Gï¬%@nal product and totaly operational, the outcome of this project
demonstrates the feasability and the practicality of implementing means of
interaction between a computer and an ordinary telephone set.",
