Further, the skip key 37 is constituted by the fast-forward key 29, and when the fast-return key 28 or the fast-forward key 29 is turned on while the stop key 34 is turned on, the system controller 5 detects this and the fast-return Key 28
Alternatively, each time the fast-forward key 29 is turned on, the disc recorder 2 is controlled so that the reproduction position of the audio data recorded on the hard disk is moved backward or forward at a predetermined interval.

The voice recording / reproducing apparatus according to the present embodiment having the above-mentioned structure is, for example, an LL (Lang) for learning a foreign language.
uage Laboratory) learning machine, but in order to use it as this LL learning machine, first, a master disk, which serves as an example in which voice data such as pronunciation by a teacher is recorded, must be created. To record the voice of this teacher and create a master disc, the teacher
After the reproduction key 35 and the recording key 36 provided on the key panel 9 shown in FIG. 2 are turned on at the same time, the voice is input by the microphone 6.

The microphone 6 collects the voice of the teacher, forms a voice signal which is an analog signal from the collected voice, and supplies the voice signal to the codec 7. The codec 7 synchronizes with a timing signal of, for example, 8 KHz from the system controller 5 to 125 μse.
The audio signal from the microphone 6 is A / D converted for each c to form, for example, 8-bit audio data and output. This audio data is supplied to the recording buffer memory 3 via the bus line 10.

The system controller 5 is 8K.
The recording buffer memory 3 is controlled so that the audio data output from the codec 7 is stored in the first storage area 3a or the second storage area 3b in response to an interrupt request by a timing signal of Hz.

As described above, each of the first and second storage areas 3a and 3b has a data area of 0.512 seconds (4096 bytes), and the system controller 5 has the first storage area. Storage area 3a or second storage area 3
When the 0.512-second audio data is accumulated in any one of b, the accumulated audio data is transferred to the disk recorder 2 at a high transfer rate of, for example, 10 Mbps at maximum.

During this time, the audio data output from the codec 7 every 125 μsec continues to be written in the other storage area. The system controller 5 controls the recording buffer memory 3 so as to use the first storage area 3a and the second recording area 3b in a time-division manner when recording the audio data.

From the first storage area 3a or the second storage area 3b of the recording buffer memory 3, the above 10
The audio data read at the speed of Mbps is supplied to the disk recorder 2, and at this time, the system controller 5 adds an absolute time code to the audio data. As a result, the disk recorder 2 records the absolute time of the audio data on the hard disk together with the audio data.

The recording of the audio data is performed until the recording stop key 38 shown in FIG. 2 is turned on and the recording stop is designated. When the recording stop key 38 is turned on and the stop of the recording is designated, the system controller 5 regards a series of the recorded voice data as one text and sets a recording start point and a recording end point of the text. The disk recorder 2 is controlled so that the address, the text number indicating the text number, and the like are recorded as so-called TOC (Table of Contents) data in the edit data area of the hard disk.

The text, which is the above series of voice data, is
You can leave it as it is, but it is easier to search if it is divided into several parts. Therefore, the teacher edits the text so as to form a plurality of sentences by dividing the text into some sentences. To divide the text into a plurality of sentences, the sentence division / fine adjustment key 2 shown in FIG.
6 is used.

The sentence division / fine adjustment key 26 is provided as, for example, one key, but three keys are provided inside, and a division key is provided in the central portion and a division point is advanced in the right portion by, for example, 64 msec. A fine adjustment key for forward movement, and a leftward portion is a fine adjustment key for backward movement for moving the division point backward, for example, for 64 msec.

The teacher reproduces the voice data of the above-described recorded text, and selects a division key provided at the center of the sentence division / fine adjustment key 26 at a desired position such as between the pronounced words. Turn on. This allows
The system controller 5 divides the text into two (when the whole is viewed, the total number of sentences is increased by one) at the location where the division key is turned on to form two sentences, and The disk recorder 2 is controlled so as to record an address indicating a recording start point and a recording end point of a sentence, a sentence number of each sentence, and the like in the edit data area.

When it is desired to finely adjust a point (division point) into which the voice data in the text is divided into two, the forward fine adjustment key or the backward fine adjustment key is turned on.
As a result, the system controller 5 moves the division point forward or backward by, for example, 64 msec, and finely adjusts the division point to set new recording start point and recording end point of each sentence formed. The disc recorder 2 is controlled so as to record the indicated address, the sentence number of each sentence, and the like in the edit data area.

When it is desired to connect the two sentences formed by performing the above division, the sentence connection key 27 is turned on while stopped at the last position of the current sentence. As a result, the system controller 5
Connects the current sentence and the next sentence (the whole sentence number is reduced by one when viewed as a whole), and the recording start point and the recording end point of the sentence formed by the above connection are determined. The disk recorder 2 is controlled so as to newly record the indicated address and sentence number in the edit data area.

When the text and the sentence are formed in this way, the text number, the sentence number and their respective recording addresses are recorded in the edit data area of the hard disk as described above. Therefore, it is possible to specify the desired text and sentence voice data. Therefore, when it is desired to delete unnecessary text, the text back key 30 or the text advance key 31 is used to select the text to be deleted. The system controller 5 controls the text number display section 20 to count down or up the displayed text number each time the text back key 30 or the text forward key 31 is turned on. The teacher selects the text to be deleted based on the text number displayed on the text number display section 20 and turns on the text deletion key 23. As a result, the system controller 5
Controls the disc recorder 2 so as to delete the voice data of the selected text and delete the addresses indicating the recording start point and the recording end point of the deleted text recorded in the edit data area. To do.

When it is desired to delete an unnecessary sentence, the sentence backward key 32 or the sentence forward key 3
Select the sentence you want to delete by 3. That is,
The system controller 5 controls the sentence number / sentence end display portion 21 so as to count down or count up the sentence number to be displayed each time the sentence backward key 32 or the sentence forward key 33 is turned on. The teacher has this sentence number /
The sentence to be deleted is selected based on the sentence number displayed on the sentence end display portion 21, and the sentence deletion key 24 is turned on. As a result, the system controller 5 deletes the voice data of the selected sentence and also deletes the addresses indicating the recording start point and the recording end point of the deleted sentence recorded in the edit data area. Then, the disk recorder 2 is controlled.

In order to prevent accidents due to erroneous operations, the system controller 5 deletes the selected text or sentence only after the text delete key 23 and the sentence delete key 24 are kept on for one second. The above-mentioned control is performed.

When the teacher forms the master disk in this manner, the student can learn. The student reproduces the audio data recorded on the master disk (hard disk) to practice pronunciation. That is, when the student wants to reproduce from the first sentence of the first text among the texts and sentences recorded on the hard disk, he or she turns on the reproduction key 35. The system controller 5 uses the T recorded in the edit data area in advance before reproduction is designated.
By reproducing the OC data, the recording position of the audio data is recognized, and when the reproduction is specified, the reproduction head is moved to the position where the specified audio data is recorded to start the reproduction. Then, the disk recorder 2 is controlled. As a result, of the audio data recorded on the hard disk, the reproduction is started from the audio data of the sentence number 1 in the text number 1.

The reproduced voice data includes the voice data produced by the teacher and an absolute time code indicating the absolute time of the voice data.

The system controller 5 processes the audio data read from the hard disk for 0.512 seconds corresponding to the storage capacity of the first storage area 4a or the second storage area 4b of the reproduction buffer memory 4. (409
6 bytes) as one unit, and the first storage area 4a or the second storage area 4b is controlled so as to transfer and write at high speed. At the same time, the system controller 5 supplies the 8 KHz timing signal as an interrupt request signal to the first storage area 4a or the second storage area 4b. As a result, the audio data written in the first storage area 4a or the second storage area 4b is sequentially read out, for example, as 8-bit audio data every 125 μsec, and the codec 7 is transmitted via the bus line 10. Is supplied to.

The system controller 5 controls the disk recorder 2 so as to read the next data from the hard disk when either one of the storage areas 4a and 4b becomes empty. During this period, the audio data is continuously transferred from the other storage area to the codec 7 every 125 μsec. The system controller 5 controls the reproduction buffer memory 4 so as to use the first storage area 4a and the second recording area 4b in a time-division manner when reproducing the audio data.

The codec 7 has the storage areas 4 described above.
The audio data supplied from a and 4b are D / A converted to form an analog audio signal, which is supplied to the speaker device 8. As a result, the student who pronounces the teacher's voice or the like from the speaker device 8 performs pronunciation practice or the like according to the teacher's voice that is pronounced from the speaker device 8.

The system controller 5 reproduces the data indicating the text number and the sentence number of the voice data being reproduced from the TOC data and supplies them to the codec 7. Codec 7 above
Supplies the data indicating the text number and the sentence number to the text number display unit 20 and the sentence number / sentence end display unit 21, respectively. As a result, the text number display section 20 and the sentence number /
In the sentence end display portion 21, the text number and sentence number of the audio data being reproduced are displayed.

The absolute time code of the audio data reproduced together with the audio data is supplied to the counter 22 via the codec 7. As a result, the absolute time code of the audio data currently being reproduced is displayed on the counter 22.

In reproducing such audio data, the system controller 5 detects that the stop key 34 shown in FIG. 2 is turned on, or all the audio data recorded in the hard disk is reproduced. It continues until it detects that playback has ended.

The above description is for the case where it is desired to reproduce from the first sentence of the above-mentioned first text. However, when reproducing a desired text or sentence, this desired text or sentence is reproduced. It is possible to perform so-called retrieval, which is designated and reproduced.

That is, when the student turns on the text backward key 30 and the text forward key 31, the system controller 5 detects this and the respective keys 3
The text number display section 20 is controlled so that the displayed text numbers are counted down or counted up by one each time 0, 31 is turned on. Further, when the student turns on the sentence backward key 32 and the sentence forward key 33, the system controller 5 detects this, and each time the keys 32 and 33 are turned on, the sentence number to be displayed is incremented by one. The sentence number / sentence end display portion 21 is controlled so as to count down or count up.

The student selects desired voice data based on the text number and sentence number displayed on the text number display section 20 and the sentence number / sentence end display section 21. After selecting the desired audio data, the reproduction key 35 is turned on. The system controller 5 uses the playback key 35.
When is turned on, the disc recorder 2 is controlled so as to reproduce the voice data of the selected text number and sentence number. As a result, the disc recorder 2 reproduces the voice data of the selected text number and sentence number, and the speaker device 8 produces a sound.

To perform a more detailed search, the student selects and reproduces the desired text and sentence as described above, and during this reproduction, turns on the fast-reverse key 28 or the fast-forward key 29. .. When the system controller 5 detects that the fast-return key 28 or the fast-forward key 29 has been turned on during reproduction, only while the keys 28 and 29 are turned on, for example, 2 to
The disk recorder 2 is controlled so as to perform the interlaced reproduction every 3 seconds, and the absolute time code is set to the above 2
The above counter 22 should be advanced or returned every 3 seconds at high speed.
To control.

Here, the fast-return key 28 or the fast-forward key 29 is turned on to perform the interlaced reproduction every 2-3 seconds to perform a detailed search of the voice data in the sentence, but a slightly rougher search. You may want to do
In the audio recording / reproducing apparatus, the stop key 34, the fast-reverse key 28, and the fast-forward key 29 constitute a skip key 37. While the stop key 34 is turned on, the fast-return key 28 or the fast-forward key 29 is turned on. When operated, the system controller 5 detects this, and every time the fast-return key 28 or the fast-forward key 29 is turned on, the reproduction position of the audio data recorded in the hard disk is moved backward at a predetermined interval. Alternatively, by controlling the disk recorder 2 so as to move it forward, a rough search is possible.

That is, the operation of the voice recording / reproducing apparatus at the time of performing the rough search is shown in the flowchart of FIG. The flow chart shown in FIG. 3 starts when the audio data is recorded on the hard disk, and proceeds to step S1.

In step S1, the system controller 5 determines whether or not the stop key 34 is turned on and then the fast-forward key 29 is turned on. If YES, the process proceeds to step S2 and NO. In the case of, it progresses to step S6.

In step S6, the system controller 5 determines whether or not the stop key 34 is turned on and then the fast-return key 28 is turned on. If YES, the process proceeds to step S7. If NO, the process returns to step S1 and the routines of steps S1 and S6 are repeated.

Since the step S7 is performed when the stop key 34 is turned on and then the fast rewind key 28 is turned on, the system controller 5 detects this and the stop key 34 is turned on. Then, every time the fast-reverse key 28 is turned on once, the counter 22 is controlled so as to perform skip return such that the absolute time code is returned by, for example, 5 minutes, and the process proceeds to step S3.

Since the step S2 is performed when the stop key 34 is turned on and then the fast-forward key 29 is turned on, the system controller 5 detects this and the stop key 34 is turned on. Every time the fast-forward key 29 is turned on once, the counter 22 is controlled so as to carry out skip feed for advancing the absolute time code by, for example, 5 minutes, and the process proceeds to step S3.

In step S3, whether or not the system controller 5 skips the recording frontmost portion or the recording last portion (hereinafter, referred to as the end) of the text by performing the skip forwarding or the skip returning. If YES, the process proceeds to step S8, and if NO, the process proceeds to step S4.

In the step S8, the skip forward or skip return causes the end of the text to be exceeded, so the system controller 5
Controls the counter 22 to display, for example, the absolute time code at the end of the text (the absolute time code of the voice data at the beginning of the text or the absolute time code of the voice data at the end of the text), and step S
Go to 4.

In step S4, the system controller 5 determines whether or not the reproduction key 35 is turned on. If YES, the process proceeds to step S5 and NO.
In the case of, the step S4 is repeated until it is determined that the reproduction key 35 is turned on.

In step S5, the system controller 5 controls the disk recorder 2 so as to reproduce the audio data selected by the skip feed or skip return, and ends the processing.

In the skip feed and skip return, the audio data to be reproduced as described above can be interlaced at intervals of, for example, 5 minutes, and therefore, rather than the detailed search by the interlaced reproduction every 2-3 seconds described above. A rough search can be enabled. For this reason, when searching for desired voice data from voice data over a long period of time, first,
By performing a rough search by the skip feed and skip return and a fine search by the interlaced reproduction every 2-3 seconds, desired voice data can be searched earlier. This is because not only when the student searches for the desired audio data from the master disk created in advance by the teacher, but also when the teacher creates the master disk, the desired audio data can be searched quickly. It is possible to speed up the production of the master disc.

For skip feed and skip return, the fast return key 2 is pressed while the stop key 34 is turned on.
Since it can be executed by turning on the 8 or the fast-forward key 29, there is no need to provide a special dedicated key,
It is possible to reduce the size of the key panel. Further, the skip key 37 is composed of the stop key 34, the fast return key 28 and the fast forward key 29, but this is provided separately from the stop key 34, the fast return key 28 and the fast forward key 29. May be.

In the skip feed and skip return, the reproduction position is moved at the interval of 5 minutes, but this time interval may be arbitrary. In the skip feed and skip return, the reproduction position is moved at the interval of 5 minutes, and when the reproduction key 35 is newly turned on, reproduction is performed from the moved position.
In this case, without waiting for the reproduction key 35 to be newly turned on, the reproduction may be automatically performed from the position after the movement.

In the above description of the embodiment, for example, the codec 7 outputs the supplied audio signal by 125 μse.
A / D conversion is performed for each c, and the recording buffer memory 4 is provided with the first and second storage areas 4a and 4b for 0.512 seconds, respectively. ,
Although a specific numerical value is used for more detailed description, it is needless to say that the numerical value is not limited to the above numerical value and may be arbitrary.
