Therefore, the disk recorder 2 has two recording / reproducing systems for recording / reproducing provided on the upper surface side and the lower surface side of the one hard disk, respectively, and two recording / reproducing systems on the upper surface side and the lower surface side of the other hard disk, respectively. It has a total of four recording / reproducing systems including two recording / reproducing systems provided for performing recording / reproducing.

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 voice data is performed until the recording stop key 34 shown in FIG. 2 is turned on and the recording stop is designated.

When the recording stop key 34 is turned on and the recording is stopped, the system controller 5 sets the recording start point and the recording of the text as a series of the recorded voice data. TOC for the end point address, text number indicating the text number, etc.
The disk recorder 2 is controlled to record the data in the edit data recording area of the hard disk.

The text voice data, which is a series of voice data, may be left as it is, but it is easier to search for desired voice data if it is divided into several pieces. For this reason,
The teacher edits the text so that the text is divided into several sentences to form a plurality of sentences.

To divide the text into a plurality of sentences, the sentence division / fine adjustment key 26 shown in FIG. 2 is used.
To use. The sentence division / fine adjustment key 26 is provided as, for example, one key, but three keys are provided inside, and the center portion is the division key, and the right portion is the advance fine for advancing the division point by, for example, 64 msec. The adjustment key, and the left portion is a backward fine adjustment key for moving the division point backward, for example, for 64 msec.

The teacher reproduces the voice data of the recorded text, and selects a division key provided at the center of the sentence division / fine adjustment key 26 at a desired position, for example, between 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 the recording start address, recording end address, sentence number of each sentence, etc. in the edit data recording area.

When it is desired to finely adjust a point (divided point) obtained by dividing the voice data in the text into two parts, 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 64 msec, for example, and finely adjusts the division point to newly record start address and recording end address of each sentence. The disk recorder 2 is controlled so as to record the sentence number of each sentence in the edit data recording 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 address, the recording end address and the recording end address of the sentence formed by the above connection. The disk recorder 2 is controlled so as to newly record a sentence number or the like in the edit data recording area.

When the text and sentence are formed in this manner, the text number, sentence number, recording address, etc. are recorded in the edit data recording area of the hard disk as described above. Therefore, when it is desired to delete unnecessary text, the text to be deleted is selected by the text backward key 30 or the text forward key 31.
That is, the system controller 5 controls the text number display unit 20 so as to count down or count up the displayed text number each time the text backward 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 deletes the voice data of the selected text and deletes the addresses indicating the recording start point and the recording end point of the deleted text recorded in the edit data recording area. The disk recorder 2 is controlled as described above.

If 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 deletes the addresses indicating the recording start point and the recording end point of the deleted sentence recorded in the edit data recording area. The disk recorder 2 is controlled as described above.

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.

Here, such editing work is performed by the sentence division / fine adjustment key 26 and the sentence connection key 27.
Alternatively, the voice recording / reproducing apparatus according to the present embodiment can output the voice data of the text by simultaneously turning on the sentence division / fine adjustment key 26 and the sentence automatic division key 37. It can be automatically divided into audio data of multiple sentences.

The operation of the audio recording / reproducing apparatus according to this embodiment at the time of automatic sentence division is shown in the flowchart of FIG. In the flowchart shown in FIG. 3, the text backward key 30 is pressed after the recording of the voice data is completed.
Or, the text advance key 31 selects the text to be automatically divided into sentences, and the sentence division / fine adjustment key 26 and the sentence automatic division key 37 are turned on at the same time during the stop without any operation designation. The procedure starts with step S1.

In step S1, the system controller 5 reproduces the voice data of the selected text at high speed, and the process proceeds to step S2.

In step S2, the system controller 5 detects whether or not the voice data reproduced at high speed includes silent voice data for a predetermined time or longer, and NO
If so, the process proceeds to step S3, and if YES, the process proceeds to step S5.

That is, the system controller 5
Is the audio data reproduced from the hard disk,
As described above, the control is performed so that the audio data is written in the reproduction buffer memory 4. At this time, the system controller 5 determines that at least one sample of the audio data of 128 samples (16 msec) has the maximum amplitude of 1.
Whether or not the voice data exceeds 1/10 of the maximum amplitude, for example, 13 times (1
6 × 13 = 208 msec) or more is determined. Then, when the voice data exceeding 1/10 of the maximum amplitude does not continue for 13 times or more, for example, it is determined to be a silent portion, and the process proceeds to step S5.

If the voice data exceeding 1/10 of the maximum amplitude continues for 13 times or more, it is regarded as a voiced portion and the process proceeds to step S3.

In step S5, step S2
Since it is determined that the voiced portion is a silent portion, when the system controller 5 detects a voiced portion after the silent portion, for example, a predetermined time (for example, 512 msec) before the head of the voice data of the voiced portion. And the recording start address and recording end address of the sentence before the division point, and the recording start address of the sentence after the division point.
The recording end address is stored and the process returns to step S2.
The routines of steps S2 and S5 are continued until the system controller 5 detects no silent portion in step S2. Therefore, the voice data of the text is divided into a sentence and a sentence at a portion having a silent portion for the predetermined time or longer. Since having a silent portion for a predetermined time or longer corresponds to, for example, a word pronounced by a teacher, there is no problem even if division is performed at a portion having a silent portion for a predetermined time or longer.

On the other hand, in step S3, since no silent portion is detected, the system controller 5 determines whether or not the voice data of the selected text has been reproduced to the end. If YES, the process proceeds to step S4. , N
In the case of O, step S3 is repeated until it is determined in step S3 that the voice data of the selected text has been reproduced to the end.

In step S4, the system controller 5 writes the recording start address and recording end address of each sentence formed and stored by performing the above-described division into the edit data recording area of the hard disk. Control the recorder 2 and finish.

In this way, in the voice recording / reproducing apparatus according to the present embodiment, the system controller 5 operates the text voice data within the voice data by turning on the sentence division / fine adjustment key 26 and the sentence automatic division key 37 at the same time. The silent section is detected, and the disc recorder 2 is controlled so as to automatically divide the silent section into sentences and sentences. Therefore, it is possible to save the troublesome work of manually dividing the voice data of the text into a plurality of sentences.

When the master disk is formed by manually or automatically editing the audio data recorded on the hard disk into text and sentences, and it is desired to check whether or not the master disk is correctly edited. There is. In particular, the division point between the sentence and the sentence is delicate, and the setting of this division point becomes important during reproduction. The dividing point is the key panel 9
This can be confirmed by turning on the sentence end reproduction key 25 provided in the.

That is, when the sentence end playback key 25 is turned on while the sentence is stopped, the system controller 5 causes the audio data of the sentence to be played for the last predetermined time (for example, 1 to 2 seconds). The disc recorder 2 is controlled so as to reproduce the data. Thereby, the sentence and the division point of the sentence can be confirmed quickly and easily.

If there is a problem with the division point, the sentence division / fine adjustment key 26 may be used to move and adjust the division point as described above.

When the teacher completes 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. As described above, the TOC data such as the recording start address and the recording end address of the audio data recorded on the master disk is recorded in the edit data recording area. Therefore, the system controller 5
Recognizes the recording position of the voice data of each text and each sentence by reproducing the TOC data previously recorded in the edit data recording area before the reproduction is designated.
Then, when the reproduction key 35 is turned on, the disk recorder 2 is controlled so that reproduction is started from the audio data of sentence number 1 in the text number 1 of the audio data recorded in the hard disk. ..

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 uses the 8 KHz timing signal as an interrupt request signal and supplies it to the first storage area 4a or the second storage area 4b. Thereby, the first storage area 4a
Alternatively, the audio data written in the second storage area 4b is
For example, 8-bit audio data is sequentially read every 125 μsec and supplied to the codec 7 via the bus line 10.

The system controller 5 controls the disk recorder 2 so as to read the next data from the hard disk when 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
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 teacher's voice or the like is produced from the speaker device 8. The students practice pronunciation and the like according to the voice of the teacher pronounced from the speaker device 8.

The system controller 5 reproduces the data indicating the text number and 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 (elapsed time in reproduction) of the audio data currently being reproduced is displayed on the counter 22.

In reproducing the audio data as described above, 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 was for the case where it is desired to reproduce from the first sentence of the above-mentioned first text, but 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 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 a desired text or sentence based on the text number and the sentence number displayed on the text number display section 20 and the sentence number / sentence end display section 21. After selecting the desired text or sentence, the reproduction key 35 is turned on. When the reproduction key 35 is turned on, the system controller 5 controls the disc recorder 2 so as to reproduce the voice data of the selected text or sentence. As a result, the voice data of the selected text or sentence is reproduced and the speaker device 8 produces a sound.

In order 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 rewind 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
