2. Device for fast replay; voice messages containing a serially-connected analog-to-digital converter, a random access memory and an output digital-to-analog converter, two registers and a control unit with a clock pulse generator, characterized in that, in order to increase the intelligibility of the message, the second and third operational ones are added to it memory devices, four switches, four counters and a block for determining the parameters of a segment, with:) the output of the first operational memory The alarms are connected to the input of the output digital-to-analog converter through the second and third operative storage devices connected in series, the address and control inputs of the operational storage devices are connected via the first, second and third switches, respectively, to the counter outputs, and the control inputs of the switches are connected to the corresponding outputs of the control unit, the inputs of which are connected through the registers, the fourth switch and the unit for determining the parameters of the segments with the output of the second opera The primary memory is connected to the generator of clock pulses, and the fourth to the corresponding output of the control unit.

The invention relates to speech informatics and can be used for accelerated listening of phonograms when searching for voice messages of a given content on long-duration media.

The aim of the invention is to increase the intelligibility of voice messages, which are rapidly reproduced by extracting segments of the reader that are read at an increased rate, and then compiling part of the segments.

The proposed method is based on introducing the operation of checking the belonging of each of the successive segments into which the phonogram is partitioned, to that stationary sound, the initial segment of which was last included in the compiled output message. If such an accessory is set, this segment, which is excessive for transmitting meaning, is not compiled with a quick listen. Due to such decimation, the output message does not contain repeating but belonging to one sound segments, its duration is reduced in relation to the input duration several times, which makes it possible to speed up the reading of the original phonogram accordingly. The continuity of the message being listened is ensured by the elastic delay of the compiled signal after the com- munication of the voice message.

The drawing shows a block diagram of a device for accelerated reproduction of voice messages.

The device contains input analog-digital converter I, random access memory 2-4, output digital-to-analog converter 5, switches 6-9, counters 10-13, b. Uc 14 determine the parameters of the segment, registers 15 and 16, the generator 17 clock pulses and block 18 controls. The input of the device through 5 analog-to-digital converter 1 and serially connected random access memory 2-4 is connected to a digital-to-analog converter 5, the output of which is the output of the device.

The outputs of the first 6, second 7 and third 8 km. Mutators are connected to the corresponding inputs of the operational storage devices, and the outputs of the fourth switch 9 through registers 15 and 16 are connected to the inputs of the control unit 18, the outputs of which are connected to the control inputs switches 6 - 9. The inputs of three switches are connected to the outputs of the counters: the first switch is connected to the first 10 and second 11 meters, the second to the second 11 and third 12 meters, the third to the third 12 and fourth 13 meters, the input of the fourth switch 9 is connected to the output of block 14 EFINITIONS parameters segments having an input coupled to the output of the second RAM circuit 3. Inputs

The 5 first three counters 10-12 are connected to the generator of 17 clock pulses, and the input of the fourth to the corresponding output of the control unit 18.

The device works as follows.

0 The input signal enters the device at a higher speed and is converted into a digital form of analog-digital converter I and is recorded at the rate of arrival in the first random access memory 2, from where it is segment by segment with a large

5 is sent to the second random access memory 3, the output of which removes signals to determine the parameters of the segments in the corresponding block 14. The parameters of the segment, depending on the state of the switch 9, are sent to register 15 or 16. The contents of the registers are compared in block 18 of control, where it is decided whether the compared segments are segments of one stationary sound, and if they are not, the control unit sends the corresponding signals to the switches 6-9 and the fourth counter 13, which results in transferring this segment to random access memory 4 for subsequent output at normal speed via output digital-to-analog converter 5. The necessary ratio between the write, census and output speeds is provided by counters 10-12, receiving clock pulses from the generator 17 clock

the parameters of the segment compiled last in the random access memory 4 are then compiled, this segment arriving from the second random access memory 3 is not compiled, which ensures that a compressed message arrives at a normal rate is output at a normal rate. It was established experimentally that to ensure the normal operation of this digital elastic delay system, the volume of the last operational memory must be sufficient to store one second of compiled speech. At the same time, the comprehensibility of the compiled messages reaches 95%, and the rate of listening to records received by telephone is three.
