Audio-visual language training system - has digital recording representing reproduced spoken text compared with manually entered data

摘要

The language training system has an original set of spoken information recorded magnetically along separate tracks as equivalent digital and analogue recordings. The analogue recording is scanned by reproduced by an electroacoustic transducer (3) with the digital recording simultaneously scanned to supply information to the woring memory of a microcomputer (7). The information supplied to the memory from the digital recording can be compared with data entered via a manual data input (6), sentence by sentence and any errors between them can be indicated on a display screen (12). The sum of the errors may be indicated as a numerical character on the display screen (12) at the end of the comparison.
