The present invention relates to a voice memory device for practicing language or music with voice, in particular, a voice memory device most suitable for portable use.

Recently, with the so-called international wave, interest in foreign languages has increased, and a language exerciser with a portable voice memory device that can practice foreign language conversation at any time has been proposed.

Such a language practice apparatus includes a combination of a magnetic card recording a single piece of voice data corresponding to a series of sentences, and a reproducing control device which repeatedly outputs the voice data of the magnetic card as reproducing sounds through earphones or the like. In particular, the reproduction control apparatus reads out the audio data from the magnetic card according to the insertion of the magnetic card, transmits the audio data to the internal memory device, and outputs the audio data stored in the internal memory device as the reproduction sound. .

In the above conventional configuration, since only the audio data corresponding to one sentence is recorded for one magnetic card, in order to perform the assembly exercises corresponding to the plurality of sentences, it is necessary to carry several magnetic cards. Inconvenient in use.

In addition, it is inconvenient in this point because it is necessary to change the magnetic card every time the contents of the exercise are changed, and at the same time, the time for transferring the magnetic data to the internal memory device of the magnetic card is relatively long.

In addition, since the audio data is read from the magnetic card, a card transmission mechanism including a motor and a flywheel, a magnetic head, and the like are required, resulting in a complicated structure and an increase in the failure rate, and reliability of the service life. Moreover, since the current consumption of the card transfer mechanism is relatively large, continuous usability is poor when the power source is used as a battery for carrying. However, when a large capacity battery is used, the weight increases, which causes problems in portability.

In particular, in terms of portability, the weight of the card transfer mechanism itself is relatively large, which is a serious problem. Furthermore, since a magnetic card has a defect that it is easy to be affected by a magnetic field, it is necessary to be careful not to get close to the magnet, which is not preferable in view of simplicity.

Further, since the reproduction control apparatus is limited to reproducing the sound data stored in the magnetic card, there is a disadvantage in that, for example, it is inconvenient when performing the voice comparison exercise between the reproduced sound and its own generated sound.

The present invention has been made in view of the above circumstances, the portability of the target sound and usability at the time of carrying can be improved, the practice of language and the like can be efficiently performed by the voice, and the reliability of the performance can be improved, and further, the voice comparison It is to provide a voice memory device with an effect such as simple practice.

The voice memory device according to the present invention is configured to digitally store and store a plurality of voice data with respect to a first solid state memory circuit built in a card type external memory device. In addition to storing the data in the second solid state memory circuit, a voice control device for selectively reading out the stored sound data of the first solid state memory circuit and the second solid state memory circuit and converting it into an analog voice signal is provided. Consists of.

When the voice is stored in the second solid state memory circuit by the voice control device, the display control device displays data indicating the recording time corresponding to the unstored area of the voice data in the second solid state memory area.

Therefore, the user can perform recording while checking the data of the indicator, thereby avoiding an inconvenience caused by lack of recording capacity.

If the voice control device selectively specifies digital voice data stored in the first solid state memory circuit and the second solid state memory circuit of the external memory device, the voice data is read out and converted into an analog voice signal. The playback sound corresponding to the analog audio signal is output from the playback device.

In this case, since the plurality of voice data are stored in the first solid state memory circuit, the user can select and listen to arbitrary voice data of the first solid state memory circuit and the second sound memory of the second solid state memory circuit. Voice comparison exercises such as language, music, and the like can be performed based on reproduction sounds corresponding to the respective voice data.

Hereinafter, an embodiment in which the present invention is applied to a language exerciser will be described with reference to the drawings.

The memory IC 10, which is a solid state memory circuit, is embedded.

In this case, in the memory IC 10, voice data corresponding to a plurality of sentences in foreign languages are digitally stored and stored. An example of the address map is shown in FIG.

On the side of the IC card 9, a plurality of contacts 11 for signal input / output are provided, and in the state where the IC card 9 is inserted into the card insertion opening 5, the contact 11 is the main body case 1.

In Fig. 1, reference numeral 13 denotes a centralized control device which also serves as a voice control device and a display control device, and includes a control circuit including a microcomputer in addition to the above-described key input unit 2 and microphone 3 ( 14) an internal memory 17 as a second solid state memory circuit composed of a speech analysis synthesis circuit 15, a signal conversion circuit 16, for example, RAM, including an A-D converter, a D-A converter, and the like. ) Has a configuration that combines.

At this time, the signal switching circuit 16 has a first state and voice which allows data transmission and reception through the above-described connector 12 between the voice analysis synthesis circuit 15 and the memory IC 10 which is an external memory. It has a data selection function that can select a second state that allows transmission and reception of data between the analysis synthesis circuit 15 and the internal memory 17, and the switching of each state is performed by the control circuit 14. It is to be performed by.

In addition, the speech analysis synthesis circuit 15 performs an A-D conversion operation for converting the voice input through the microphone 3 into digital voice data Sd, and the control circuit from the memory IC 10 or the internal memory 17. Is configured to selectively execute the D-A conversion operation of reading the voice data designated by (14) or synthesizing the analog voice signal Sa based on the digital voice data Sd read as such. After the end of the D-A conversion operation, an end signal is generated and fed back to the control circuit 14.

Then, the control circuit 14 switches the LCD 4, the voice analysis circuit 15, and the signal on the basis of various commands input from the key input unit 2, data stored in advance in the control program and the internal memory circuit. The control of the circuit 16 and the address control of the memory IC 10 and the internal memory 17 are performed as follows. 18 is a reproducing apparatus, which comprises an amplifier 19 in addition to the above-described volume 7 and earphones 8. The amplifier 19 is provided with a volume (7) from the speech analysis synthesis circuit (15). The amplified analog voice signal Sa is input to the earphone 8. Therefore, when the analog voice signal Sa is output from the voice analysis synthesis circuit 15, the reproducing sound corresponding to the voice signal Sa is output from the earphone 8, and the volume can be adjusted by the volume 7. have.

In the following, the control circuit 14 described above will be described together with the overall operation of the control contents.

(I) When we record voice…

In this case, the key input unit 2 selects to store the recorded data in the internal memory 17.

When such a selection is made, the control circuit 14 switches the signal switching circuit 16 to the second state based on the command from the key input section 2.

When the recording command is transmitted from the key input unit 2, the control circuit 14 switches the voice analysis synthesis circuit 15 to the A-D conversion operation execution state and the voice data in the storage area of the internal memory 17. The recordable time is calculated based on the storage capacity of the meaning storage area, and the result of the calculation is displayed on the LCD4.

At this time, the ratio of the recordable time and the maximum allowable recordable time may be displayed.

When a voice is input through the microphone 3 in this state, the voice analysis synthesis circuit 15 converts the voice into digital voice data Sd, and the digital voice data Sd is stored in the internal memory 17. It is stored (that is, recorded) at a predetermined address. Then, the control circuit 14 recalculates the recordable time and changes the display of the LCD 4 in accordance with the recording as described above.

(II) When the audio data stored in the memory IC 10 and the internal memory 17 are alternately reproduced.

In this case, digital voice data stored in the memory IC 10 and the internal memory 17 (recorded in the internal memory 17 by the user as described above (I) and previously stored in the memory IC 10). The key input unit 2 selects the audio data to be reproduced.

When such a selection is made, the control circuit 14 alternately switches the signal switching circuit 16 to one of the first state and the second state based on the command from the key input unit 2 and the selected state. The type of the audio data (the address in which the audio data is stored) is displayed on the LCD4.

The control circuit 14 switches the voice analysis synthesis circuit 15 to the D-A conversion operation execution state when the reproduction command is received from the key input unit 2. Accordingly, the voice analysis synthesis circuit 15 stores the memory. The voice data selected as described above among the voice data stored in the IC 10 and the internal memory 17 are alternately directly read from the memory IC 10 or the internal memory 17 and transmitted to the voice analysis synthesis circuit 15. .

Then, the voice analysis synthesis circuit 15 converts the digital voice data S＇d read as described above into an analog voice signal and transmits the same to the reproducing apparatus 18, whereby the reproducing sound is output from the earphone 8.

In this way, the output of the reproduced sound ends, and the control circuit 14 which has received the end signal from the speech analysis synthesis circuit 15 repeats the above-described output operation of the reproduced sound by the number of times predetermined by the key input unit 2. .

For example, the user alternately or selectively changes the voice data corresponding to a plurality of sentences stored in advance with respect to the memory IC 10 of the IC card 9 and the voice data recorded by the user with respect to the internal memory 17. It can be played and listened to, thereby effectively performing the language's hearing practice and speaking practice.

According to this embodiment described above, many effects can be obtained as described below.

That is, since the audio is reproduced using the IC card 9 in which sound data corresponding to a plurality of sentences is stored, the practice of hearing a plurality of sentences can be performed simply by carrying one IC card 9 or several. This improves portability and is convenient in practical use.

In addition, since the voice can be recorded in the internal memory 17, the speaking practice can be performed in parallel, and the efficiency of the speech comparison practice of language is improved. Since data reading from the IC card 9 is much faster than the conventional magnetic card, it is possible to quickly reproduce a desired sentence and improve convenience in use.

Since the memory IC 10 of the IC card 9 is directly accessed, a mechanism part having a complicated structure is not required as in the prior art, and the failure rate is reduced, and power consumption and weight are reduced.

As a result, the reliability of the life can be improved, and when the battery is used for carrying, the continuous use time can be extended and the portability can be improved.

Since the IC card 9 does not need to consider data destruction by magnetic, its handling becomes easy.

Furthermore, since the recordable time is displayed on the LCD 4, the recording time becomes insufficient when recording the voice, and there is no fear that the recording will be cut off in the middle.

In the above embodiment, the memory IC 10 stores voice data corresponding to a sentence of a foreign language, but instead, it is also possible to store voice data corresponding to music or the like, for example, to orchestra performance. The music can be stored as a music exerciser for karaoke, and can be used as a portable equipment for bird watching by storing wild birds' tweets.

In the above embodiment, the recording function is added to the centralized control device 13, but this may be provided on the IC card 9 as necessary.

According to the present invention, as shown by the above description, a voice type stored in the first solid state memory circuit is provided by providing a card-type external memory device having a first solid state memory circuit in which a plurality of recorded data are digitally stored. Since the data and the voice control device selectively output the voice data stored in the second solid state memory circuit as the reproduction sound, the portability and usability are improved, the language practice is performed efficiently, and the lifespan is improved. With regard to the improvement of the reliability and the continuous usability in the case where the power source is used as a battery, it is possible to obtain an excellent effect that the voice comparison practice can be easily performed.

In addition, in the second solid state memory circuit for voice recording, the display unit displays data indicating the recording time corresponding to the voice data non-storage area, thereby preventing the inconvenience caused by the lack of recording capacity. Can be.
