Computer Controlled Audio Output

In response to a request for information from an inquiry station 1, computer 2 assembles a message for delivery via phone 3.

A vocabulary of coded words is prepared in advance by sampling spoken words at 8kc. The amplitude of each sample, measured on a 0-63 value scale, is converted to a 6-bit digital character for storage in large capacity storage 4. Each spoken word, stored as a series of such digital characters, is available upon call to the computer.

In response to an inquiry, the computer calls for selected words from storage 4 and assembles an answer message in high speed storage 5 at computer speed. At a suitable time, the computer gates out at 8 kc the message, in series by digital character, to register 6. Register 6 controls summing network 7, which produces a replica of the original spoken word with an extraneous 8 kc sampling signal. Amplifier and low pass filter 8 removes the sampling signal and amplifies the audio message for transmission to phone 3.

Where high speed storage and computer processing speeds are ample, the computer, suitably programmed, provides continuously selected verbal messages for delivery via phone.
