The speech autoinformer comprises a control unit 1, a memory unit 2, a decoder 3, a low-frequency amplifier 4, a microphone 5, an encoder 6, a shift shift register 7 with a zero input, a clock generator 8 including a clock generator 9, a clock divider 10, a time divider 11 and the element NOT 12, the annular shift registers 131, ..., 13P, the AND elements 14, ..., 14P, the OR element 15 and the switch 16 with the control input. The start input of the speech autoinformer and the last bit of the ring shift register 7 are connected to the input of its first bit, the zeroing inputs of the device are connected to the zeroing inputs of the ring shift registers 131, ..., 13P, and the output of the low-frequency amplifier 4 is the output of the device. The output of decoder 3 is connected to the input of the low-frequency amplifier 4, the information input is connected to the output of the OR element 15 of the memory unit 2, and the clock input is connected to the output of the clock divider 10, the inputs of the time divider 11 and the element HE 12 of the clock generator 8 and the clock inputs of the ring registers 131, ..., 13P shift. The microphone output 5 is connected to the information input of the encoder 6, the clock input of which is connected to the output of the element HE 12 of the clock generator 8, and the output is connected to the input of the switch 16. The clock input of the ring shift register 7 is connected to the output of the time divider 11, the outputs of its bits are connected with the first inputs of AND elements 14, ..., 14P, the outputs of which are connected to the inputs of the OR element 15, and the first inputs - with the outputs of the last bits of the registers 131, ..., 13P, which are also connected to the inputs of their first bits and switch outputs 16. Exit ayuschego generator 9 is connected to the clock input of divider 10.

Voice autoinformer works as follows.

Before the device starts to work, the necessary information is recorded in the circular shift registers 13, ..., 13P of the memory block 2. In this case, the speech signals from the microphone 5 are supplied to the encoder 6, where the speech information is converted from analog form to digital sequences with an inverted 5 clock frequency FI. To record information, one or another register is selected from group 13, ..., 13P of registers of memory block 2. The choice of the register is carried out by applying a single signal at the time of recording on

10 control input of device switch 16. A signal is provided on one of the input buses. Thus, when selecting an a-ro register for recording, the signal is applied to the ith bus.

Writing to the registers 131, ..., 13P is carried out under the influence of clock pulses of frequency FI coming from the output of the clock divider 10 of the clock generator 8.

After recording information by supplying a signal (logical 1) to the start input, the device is put into operation. The signal (1) is recorded in the first bit of the ring shift register 7 of the control unit 1, is output from the output of the first bit

5 register, enters the first input of the element And 14 and opens it. Information with a frequency FI recorded in the register 131 through the open AND element 141 and the OR element 15 is transmitted to the decoder 3 and then through the low-frequency amplifier 4 to the output of the device. In decoder 3, information is converted from a digital sequence to an analog form. As soon as the output of temporary divider 11 to the input

5 of the advance of register 7, an advance signal (frequency of signals Fa) is received, logical 1 from the first bit of register 7 is written into its second bit. In the memory block 2, the signal (1) from the output of the second bit of the register 7 opens the second element And 14, and the information recorded in the register 131 begins to arrive at the output of the device. When the next 7 are received in the register

5 forward signals from the time 11 divider at the output of the device the information recorded in the registers 131 ..... 13P appears.

0 During the operation of the device, speech information is output continuously, periodically repeated, and during the time T 1 / F2, information recorded in one of the

5 registers 13, and after a period equal to pT, the transmission of information recorded in the memory unit 2 is repeated.

Time T, depending on the place of application of the speech autoinformer, may be different. Usually 25; 0.5; 1 hour

An important feature of the operation of the device is the ability to write new information to the register 13, from which at that time the information recorded previously is read.

To overwrite the information in the register 13, a signal 1 from the input of resetting the device is sent to its zeroing input. Then, a signal is provided to the input of the switch 16c of its control input, which ensures the output of the encoder 6 to the information input of the register 13, and new information is recorded through the microphone 5. The presence of single vibrators in the switch 16 allows the pulse signals at its outputs to be extended when recording.
