ABSTRACT:
A voice interactive computer system having voice digitizing circuitry for digitizing voice input from an operator. The voice digitizing circuitry is preferably placed on a computer card in operative association with a central processing unit in the computer. The digitized voice input may be selectively replayed and compared with a prerecorded language vocabulary stored on a compact disc read only memory connected to the computer. The compact disc read only memory is also used for storing software which provides interaction between the voice digitizing circuitry and the computer central processing unit and random access memory in the computer. The voice digitizing circuitry may be placed on a separate computer card positioned in a slot in a bus in operative association with the central processing unit or combined with other cards. The digitized voice input may also be stored on magnetic media such as a computer disc for later review by others, such as a teacher. A method of using the voice interactive computer system in teaching a second language to a student having proficiency in a first language is also disclosed.
