Abstract

PURPOSE:To improve the efficiency of processing by stopping sound output automatically and temporarily at a position where proper data length is obtained when stored sound data is edited and made into a document. CONSTITUTION:When sound data is inputted and stored, a voice is inputted from a sound input device 101 and consists of sound sections 201 and 203 and a silence section 202. On the other hand, a silence time threshold value Th for adding a pause code to the input voice is inputted previously from a silence time threshold value input device 103. In this case, the pause code is detected at the time of the output of the stored sound data and the sound output is stopped temporarily immediately after the pause code is detected within a predetermined time or a certain time after no pause code is detected within the constant time and the sound output is restarted on receiving a sound output restart indication from outside. Consequently, the stored sound data are edited efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an audio editing device that edits stored audio data.

[Conventional technology]

Conventionally, when editing or documenting stored audio, an operator listens to the audio recorded on a magnetic tape, detects the point where he or she wants to stop, and inputs an audio stop signal with one hand or foot. Audio playback was stopped and processing such as editing and documentation was performed.

[Problem to be solved by the invention]

In the above conventional technology, when editing the stored audio data, the operator manually stops the audio output by listening to the audio output, so the processing is inefficient and easy to make mistakes. There was a problem.

An object of the present invention is to automatically temporarily stop audio output at a point where the data length is appropriate for processing when editing, documenting, etc. stored audio data, which was conventionally done manually. The aim is to improve the efficiency of audio editing and processing, which was previously complicated.

[Means to solve the problem]

In order to achieve the above object, the present invention provides an apparatus that includes means for accumulating and outputting audio data and outputting and editing the accumulated audio data, which detects silent time of input audio when accumulating audio data, means for accumulating input audio by adding audio delimiters to that location; means for detecting said delimiters when outputting the stored audio data; If a delimiter is not detected within a certain period of time, the audio output is temporarily stopped after one hour has elapsed, and means is provided to restart the audio output after waiting for an external audio output restart instruction. It is characterized by:

In addition, for devices that do not have a means to add audio delimiters when storing audio data, there is a method for detecting the silent period of the output audio when outputting the stored audio data, and a means for detecting the silent period of the output audio when outputting the stored audio data, and a device that detects the silent period of the output audio when outputting the stored audio data, and Means to temporarily stop the audio output at that point if the silent period is detected, or at the point when the one hour has passed if the silent period is not detected within a certain period of time, wait for an instruction from the outside to restart the audio output, and restart the audio output. It is characterized by having the following.

[For production]

When adding audio delimiters when storing audio data, a threshold is set for the silent time of the audio, and the delimiter is added when the silent time in the input audio exceeds the threshold.

When editing stored audio data, if a delimiter is detected in the output audio within a predetermined period of time (if a delimiter is not added to the stored audio data, a silent period is detected), the Or, if a delimiter (silence time) is not detected within a certain period of time, the audio output is automatically temporarily stopped when the certain period of time has elapsed.

Then, when an external instruction is given to resume audio output, if the output is stopped due to a delimiter (silent time), for example, if the output is stopped from the stopped point, or if the output is stopped after a certain period of time has elapsed, Resumes output from the point where some time has been returned. This makes it possible to efficiently edit the stored audio data.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. This shows the devices that add audio delimiters when storing audio data, including an audio input device 101, a silent time measuring circuit 102, a silent time threshold input device 103, a delimiter adding circuit 104, and an audio data storage device. 105. Audio output device 106° delimiter detection circuit 107, delimiter search time threshold input device 108, output audio measurement circuit 10
9, an audio output control circuit 110, and an audio output restart signal input device 111.

When inputting and storing audio data, audio is input from the audio input transmitter 101. FIG. 2 shows an example of the voice input to the voice input device 101, which is composed of sound sections 201 and 203 and a silent section 202.

On the other hand, a silent time threshold Th for adding a delimiter to input audio is input in advance from the silent time threshold input device 103. The threshold Th is shown at 204 in FIG.

For example, in order to divide at commas, the threshold Th is 70
It is desirable to set it to about 0m5ec. Voice input device 10
1, the silent time measuring circuit 102
, the silent time length 202 of the input audio is measured, and the magnitude of the silent time is compared with a threshold value 204 inputted in advance by the silent time threshold input device 103. If the silent time exceeds the threshold value, the delimiter code adding circuit 104 to add a delimiter code to the corresponding location, and store the audio data in the audio data storage device 105.

Editing of the stored audio data is performed by outputting audio from the audio data storage device 105 to the audio output device 106.
At this time, under the control of the audio output control circuit 110, the audio output from the audio data storage device 105 is automatically stopped and restarted as follows.

When audio output from the audio data storage device 105 starts or restarts, the delimiter detection circuit 107 and the output audio time measuring circuit 109 are operated.

The delimiter detection circuit 107 is connected to the audio data storage device 10.
Regarding the audio output from 5 to the audio output device 106,
When a delimiter is detected, a delimiter detection signal is sent to the audio output control circuit 110. The output audio time measuring circuit 109 is a timer.

The elapsed time since the sound is output from the sound data storage device 105 is measured and transmitted to the sound output control circuit 110.

A predetermined time threshold is further input to the audio output control circuit 110 from the delimiter search time threshold input device 108 in advance. This threshold value specifies the time at which audio data is divided into appropriate data lengths when no delimiter is detected after a certain amount of time has elapsed. Optional.

When the audio output control circuit 110 receives and receives a delimiter detection signal from the delimiter detection circuit 107 within a time that does not exceed the time threshold input in advance from the delimiter search time threshold input device 108, the audio output control circuit 110 outputs the delimiter detection signal from the delimiter detection circuit 107 to the audio data storage device 105. temporarily stop the audio output operation. After completing the processing for the already output portion, the operator inputs an audio output restart signal using the audio output restart signal input device 111. Audio output control circuit 11
0 causes the audio data storage device 105 to restart the audio output operation upon receiving the audio output restart signal from the audio output restart signal input device 111. At this time, the audio output restart mode is also input from the audio output signal input device @ 111, and depending on the input mode, the audio output control circuit 110 starts at the time of the delimiter that stopped output or the one before the delimiter. Makes audio output restart from the delimiter point.

On the other hand, if the delimiter detection circuit 107 does not detect a delimiter within the time threshold inputted in advance from the delimiter search time threshold input device [108], after the elapse of the time threshold, the audio output control circuit 110 detects the audio data. Accumulation device 10
Similarly, the audio output operation in step 5 is temporarily stopped. After editing and documenting the already output portion, the operator inputs an output restart signal using the audio output restart signal input device 111, and the audio output control circuit 110 receives and receives the signal to output the audio from the audio data storage device 105. Resume output operation.

At this time, depending on the mode input from the audio output restart signal 111, the audio output control circuit 110 resumes audio output from the time set back by a certain return time or from the break point immediately before the stop point.

FIG. 3 shows an example of operation when a delimiter is not detected within the delimiter search time threshold, where 301 is the delimiter search time threshold, and 302 is a constant return time. This
The constant return time 302 is determined to include at least the beginning of the sentence so that if the stop point is in the middle of a sentence, the output restart point will not interfere with subsequent editing.

In the above embodiments, an example of a device having a function of adding audio delimiters when storing audio data has been described. Silent time measurement circuit 10
2. When there is no silent time threshold input device 103, delimiter code addition circuit 104, etc.), delimiter code detection circuit 1 of FIG.
By preparing a silence time measuring circuit instead of 07.

When editing audio data, if the silent time of the output audio is measured and given to the audio output control circuit 110, the audio output control circuit 110 will detect the silent time at the silent point or after a certain period of time if no silent point is detected. Similarly, audio data output can be temporarily stopped automatically. In addition,
In this case, the one-delimiter code search time threshold input device 108 becomes a silent time search time threshold input device.

〔Effect of the invention〕

As explained above, according to the present invention, when editing and documenting stored audio data, audio editing processing is carried out by automatically temporarily stopping audio output at a point with an appropriate data length that is easy to process. It has the advantage of being efficient.
