Abstract

PURPOSE:To decrease the number of times of reading out a voice message from a magnetic disk and to improve read-out efficiency of the voice message by writing the voice message whose read-out frequency is high in a RAM in advance. CONSTITUTION:A control part 6 reads out the contents of a message counter 3, reads out a voice message whose read-out frequency is high in the voice messages stored in a magnetic disk part 1 at present, and writes it in a RAM 2. This operation is executed periodically, and in the RAM 2, the voice message whose read-out frequency is high at that time point is always written. When it is requested to reproduce the voice message from a user of a telephone set 7, the control part 6 reads it out from the RAM 2, when the requested voice message is written in the RAM 2, and reads it out of the disk part 1 only when it is not written. In such a way, the number of times of reading out the voice message from the magnetic disk is decreased, and the read-out efficiency of the voice message is improved.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an audio storage device.

[Conventional technology]

A conventional audio storage device will be explained with reference to the drawings.

FIG. 2 is a block diagram showing an example of a conventional audio storage device.

In FIG. 2, a magnetic disk section 1 is a section for storing voice message data, and a line connection section 4 is a section for storing voice message data.
The audio transfer section 5a is a section that transfers audio data between the magnetic disk section 1 and the line connection section 4, and the control section 6a controls the overall operation of the conventional audio storage device. This is the part to do.

Here, when a user of the telephone 7 requests to play a voice message, the control section 6a causes the voice transfer section 5a to read out the requested voice message from the magnetic disk section 1, and
An instruction is given to transfer the data to the line connection unit 4. Audio transfer section 5
a transfers the voice message according to instructions from the control section 6a.

Through these operations, a voice message is played back to the user of the telephone 7.

In this manner, the conventional voice storage device reads voice message data from the magnetic disk section in accordance with a user's request, and reproduces the voice message by transferring the data to the user's telephone.

[Problem to be solved by the invention]

When reading data in the conventional magnetic disk device of the audio storage device described above, the time required to move the head to the track storing the data to be read is required before reading the data that is not to be read from the magnetic disk. It requires a seek time, which is , and a rotational waiting time, which is the waiting time until the sector storing the data to be read comes to the position of the head. Further, the seek time and rotational waiting time are often longer than the time to read data from the magnetic disk.

Therefore, in a method of reading voice message data from a magnetic disk device every time, as in the conventional voice storage device described above, seek time and rotational waiting time are required each time, which lowers the read efficiency of voice message data. ,
This has the disadvantage that the number of voice messages that can be played simultaneously is limited.

[Means to solve the problem]

The voice storage device of the present invention includes a first storage section that stores a plurality of voice messages, a counting section that counts the number of times each of the plurality of voice messages is read out from the first storage section, and a number of times that the voice messages are read out. a second storage section that reads out and stores voice messages having a frequency higher than a predetermined number of times from the first storage section; a line interface section that interfaces with a line; and the first storage section or the second storage section.
a transfer unit that transfers a voice message from a storage unit of the device to the line interface unit; and a control unit that controls each of the units; or a magnetic storage unit that stores voice messages in the form of a plurality of digital signals; a semiconductor storage unit that reads and stores voice messages of digital signals whose frequency is higher than a predetermined number of readout times from the magnetic storage unit; and a semiconductor storage unit that converts the input analog audio signal into a digital signal and transfers the digital signal to the magnetic storage unit. and a D-A converter circuit that converts the digital signal voice message from the magnetic storage section or the semiconductor storage section into an analog signal voice message and transfers the analog signal voice message to the line interface section. It has a transfer section.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

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

In FIG. 1, the audio storage device of the present embodiment includes a magnetic disk unit 1 that stores voice messages of a plurality of digital signals, and counts the number of times each voice message of a plurality of digital signals is read from the magnetic disk unit 1. a message counter 3 for reading out and storing voice messages whose frequency is higher than a predetermined reading count from the magnetic disk section 1; a line connection section 4 for interfacing with a line; An A-D conversion circuit (hereinafter referred to as A/DC) 51 converts the digital signal into a signal and sends it to the magnetic disk unit 1, and converts a digital signal voice message from the magnetic disk unit 1 or RAM 2 into an analog signal voice message. Consisting of an audio transfer section 5 including a D-A conversion circuit (hereinafter referred to as D/AC) 52 that transfers data to the line connection section 4, and a control section 6 that controls the entire audio storage device of this embodiment. are doing.

Next, the operation of this embodiment will be explained.

First, the control unit 6 reads the contents of the message counter 3, determines which voice message currently stored in the magnetic disk unit 1 is read out more frequently, and selects the voice message that is read out more frequently from the magnetic disk unit 1. Read, R
Write to AM2, these operations are performed periodically and R
A voice message that is frequently read out at that time is always written to AM2.

When there is a request for playback of a voice message from a telephone user, the control unit 6 determines whether the requested voice message is written in the RAM 2 or not. The voice transfer section 5 is instructed to read the voice message, and when the voice message is not written, the voice message is instructed to be read from the magnetic disk device 1.

Incidentally, when there is a request to record a voice message from the user of the telephone set 7, the voice message is always written to the magnetic disk section 1.

〔Effect of the invention〕

As explained above, the present invention allows voice messages that are frequently read out to be written in advance into the second storage section.
By reducing the number of times voice messages are read from the first storage section, and thereby reducing the seek time, rotation waiting time, etc., which are wasted time for reading voice messages from the first storage section, This has the effect of increasing the reading efficiency of voice messages.
