US 4,786,255 A · Group education system

Abstract

A group education system including a first memory for storing an original sentence group, a second memory for storing a starting address, an end address of a sentence block of an original sentence group stored in the first memory, a control circuit for controlling the selection of a playback mode and the reading order of the sentence blocks of the original sentence group stored in the first memory and the change of the pause times thereof and a third memory for storing the reading order, the starting address, the end address and the altered pause times of the selected sentence block under the control of the control circuit. Accordingly, it becomes possible to form with ease a sentence group in which the playback mode and the reproducing order of the selected sentence block are selected and the pause times between the sentence blocks are changed.

Claims6

Dependent claims

A group education system of the type which selectively records and replays spoken sentences, which are composed of words separated by pauses, wherein the system comprises:

(a) first memory means for storing data representing sentence blocks of a spoken, original sentence group;
(b) second memory means for storing a starting address and an end address of data representing each of said sentence blocks of said original sentence group data stored in said first memory means and data representing pause times between said sentence blocks;
(c) control means for controlling the selection of the order in which said sentence blocks of said original sentence group data are read out from said first memory means and for changing the pause time data stored in said second memory means for one or more selected sentence blocks so as to change the pause time lengths, said control means being connected to said second memory means for selectively reading out the data from said second memory means;
and
(d) third memory means, responsive to the control means, for storing the starting address, the end address and the changed pause time data of the one or more sentence blocks selected by said control means.

2 more elements

A group education system of the type which selectively records and replays spoken sentences which are composed of words separated by pauses, wherein the system comprises:

first memory means for storing data representing sentence blocks of spoken teaching material, less the pause times;
second memory means for storing a starting address and an end address of each of said sentence blocks stored in said first memory and data representing pause times between said sentence blocks;
control means, including selecting switches, for controlling the selection of the order in which data is readout from said first memory means and for changing the lengths of the pause times;
third memory means for storing the reading order, the starting address, the end address and the changed pause times of the sentence blocks selected under the control of said control means;
and
read control means for controlling the reading operation from said first memory means on the basis of said control means and an output signal from said third memory means.
