JPH05143090A - Speech repetitive reproducer - Google Patents

Abstract

PURPOSE:To electronically and automatically perform speech repetitive reproduction by providing a RAM where an optional part is extracted and recorded and a counter which can optionally set a blank time between the start and end of endless reproduction so as to make a speech easy to hear. CONSTITUTION:An LPF 1 attenuates an unnecessary high component and a high-frequency component of the speech and when the speech is reproduced, the RAM 3 is read out from an address specified by an address counter 6; and the read data is converted by a D/A converter 4 into an analog signal and clock signal and digital signal components are attenuated by an LPF 5 and outputted. Writing and reproduction are controlled with a store/playback signal and when the data from the RAM 3 are reproduced, the counter 41 generates the blank time after writing to the RAM 31 controlled with a write start/end signal 22. A preset signal is set in the counter 41 to determine the length of the blank time, thereby setting the time so that the speech is easy to hear.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recorder for storing and repeatedly reproducing voice words and monosyllabic words.

[0002]

2. Description of the Related Art Conventionally, in the case of repeatedly reproducing a voice or the like, it has been performed by rewinding the recorded matter on a tape recorder or the like and repeating the reproduction.

[0003]

However, the conventional repetitive reproduction system has a drawback that it requires repeated operations and shortens the life of the tape recorder or the like.

In order to eliminate this drawback, the sound is converted into digital data, which is recorded in the RAM and, when reproduced, is automatically reproduced repeatedly.

An object of the present invention is to provide an audio repeat player which electronically and automatically repeats audio reproduction.

[0006]

In order to achieve the above object, in an audio repeat player according to the present invention, an analog signal is converted into a digital signal by an A / D converter, and the digital signal is converted by a write control signal. The digital signal stored in the RAM addressed by the address counter having a preset number of counts is read out by repeatedly counting the address counter to read the digital signal stored in the RAM by the reproduction control signal, and the read digital signal is D / A. Means for returning to an analog audio signal by a converter, and re-storing the necessary portion of the signal stored in said RAM in another RAM addressed by another address counter, reading it out by a reproduction control signal, said D
It has means for switching and inputting to the / A converter, and a counter for arbitrarily setting a blank time after the signal to be stored and externally set.

[0007]

The audio repeat player according to the present invention is provided with an A / D converter for converting the audio of a portion to be repeatedly played back into a digital signal, a RAM for temporary storage, and an address counter for controlling the storage address of the RAM for playback. R as a means
It has a D / A converter for converting the data read from the AM into voice.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

In the figure, the present invention has an analog voice signal conversion means, an input means, and a counter.

The audio signal converting means includes an LPF 1 and an A / D
Converter 2, RAM 3, address counter 6, D /
It includes an A converter 4 and an LPF 5, and converts an analog signal to A /
A RAM which is converted into a digital signal by the D converter 2 and which is addressed by the address counter 6 whose count number is preset by the write / playback signal.
3, the digital signal stored in the RAM 3 by the write / playback signal is repeatedly read by the address counter 6, and the read digital signal is read by D /
The A converter 4 has a function of returning to an analog audio signal.

The input means includes a RAM 31, an address counter 32, a register 34, a matching circuit 33, and a switching circuit 12, and the signal stored in the RAM 3 is addressed by another address counter 32. RA
It has a function of re-storing a necessary part in M31, reading it by a reproduction control signal, and switching and inputting it to the D / A converter 4 by the switching circuit 12.

The counter 41 is provided with a blank time after the signal to be stored and is arbitrarily set from the outside.

In the figure, a RAM 3 stores data, and an address counter 6 which operates with a clock 21.
Addressed by.

The input audio signal is an analog signal, but is converted into a digital signal by the A / D converter 2.

The LPF 1 is for attenuating unnecessary high components and harmonics of voice. In the case of reproduction, the data is read from the RAM 3 in order from the position designated by the address counter 6, converted into an analog signal by the D / A converter 4, and the clock signal and the digital signal component are attenuated by the LPF 5 and output.

Writing and reproduction are controlled by the storage / reproduction signal. Further, after the data from the RAM 3 is reproduced and writing is finished in the RAM 31 controlled by the writing start / end signal 22, the counter 41 provides a blank time.

The length of the blank time of the counter 41 is determined by the setting of the preset signal, and the time can be made easy to hear.

[0019]

As described above, according to the present invention, an RA which temporarily converts an analog signal such as voice into digital and stores it.
By combining an address counter for sequentially designating addresses of M, a RAM addressed by the address counter, a means for converting a digital signal into an analog signal at the time of reproduction, and a control for starting and ending storage and a reproduction control circuit, Partial recording of voice, etc. and repeated playback are possible.

Further, a necessary portion can be extracted from a portion recorded for repeated reproduction, and that portion can be reproduced repeatedly, and a blank time can be set arbitrarily for easy listening.
