Is output to

Reference numeral 21 denotes a system control microcomputer. The microcomputer 21 stores the C stored in the CD storage 11.
D is managed, and the CD 12 to be used for reproduction is selected. Further, the microcomputer 21 is supplied with various data from the reproduction processing circuit 15,
A control command for instructing an operation mode and the like is supplied from the microcomputer 15 to the reproduction processing circuit 15.

Various operation keys 22 are connected to the microcomputer 21.
The display 23 is connected to display the numbers, track numbers, playback elapsed time, and the like. Further, a voice recognition circuit 25 is provided. When a voice signal is supplied from the microphone 24 to the voice recognition circuit 25, voice recognition is performed, and data of the recognition result is supplied to the microcomputer 21.

Further, the microcomputer 21 includes:
A memory 26 for storing a data table described later is connected. In this case, the memory 26 is a ROM capable of electrically erasing and writing data, or a RAM (not shown) backed up by a battery. That is, the memory 26 is a non-volatile memory. Thus, the written data can be retained even when the power is turned off.

FIG. 2 shows an example of the data table DTBL stored in the memory 26. This data table DTBL is
CD TOC data TOCD and voice recognition result data
It is a correspondence table with VRCG. Data TOCD per CD
And a set of data VRCG.

In this case, the TOC data TOCD
Is the TOC data recorded on the corresponding CD. Therefore, the data TOCD is data unique to the CD, and has different contents for each CD. The data VRCG of the result of voice recognition is data of the result of recognition of voice input by the user using the microphone 24 by the recognition circuit 25, and is generally a keyword when selecting a target CD. In the case of a word, for example, a singer's CD, the data is the result of speech recognition when the singer's name is uttered.

In such a configuration, various operations are performed
The processing is executed by the microcomputer 21 as follows. That is, [reproduction of CD by key operation] This is a case where selection and reproduction of a CD are performed by key operation as in a general CD changer.

In this case, first, a key operation for selecting a CD is performed by the key 22. Then, the microcomputer 21 controls the CD storage unit 11 in accordance with the key output, and the target CD 12 is selected and set at the reproduction position.

When the reproduction key of the keys 22 is operated, the reproduction of the CD 12 is started thereafter, the reproduction signal is supplied from the optical pickup 14 to the reproduction processing circuit 15, and the audio signal reproduced from the CD 12 is supplied to the terminal 16. A signal is output.

Thus, this CD changer can select and reproduce a CD in the same manner as a general CD changer.

[Registration of CD] This is a case where audio data is registered so that a CD in the CD storage section 11 can be selected by a keyword voice.

In this case, first, a key operation for selecting a CD is operated by the key 22, and a target CD 12 is selected and set to a reproduction position, as in the case of [CD reproduction by key operation]. . At this time, the CD storage unit 1
The CDs stored in 1 may not be continuously stored in the storage position. At this point, the TOC of the CD 12 is
, For example, “AAAA” is read.

Subsequently, when a registration key among the keys 22 is pressed, the TOC data read from the CD 12, in this case, the data "AAAA" is stored in the data table DTBL of the memory 26 as shown in FIG. The data is written in the TOCD column, and then the microcomputer 21 enters a state of performing voice recognition. Therefore, while pressing the registration key, a keyword for identifying the CD 12 toward the microphone 24, for example, the CD 12 is the C of the singer "Mariah Carey".
If D, say "Mariah Carry". Then, the voice signal is supplied to the voice recognition circuit 25 and is converted into the corresponding voice recognition data “Maria Carry”.

When pressing of the registration key is stopped, FIG.
As shown in the figure, the voice recognition data "Mariah Carry"
Is T in the data column VRCG of the data table DTBL.
The data is written in a column paired with the column in which the OC data “AAAA” is written. Then, the registration of the first CD 12 is completed.

Thus, the CD 12 to be registered is selected,
When a keyword for selecting and reproducing the CD 12 is uttered, a set of the TOC data of the CD 12 and the data of the voice recognition result of the keyword is registered in the data table DTBL.

[Selection of CD by Voice] This is a case where a CD to be reproduced is selected from the CDs in the CD storage unit 11 by voice.

In this case, the microphone 2
If the keyword for identifying the target CD 12 toward 4, for example, the CD of the singer "Billie Joel" is used, "Billie Joel" is uttered. Then, the voice signal is supplied to the voice recognition circuit 25 and is converted into the corresponding voice recognition data "Billie Joel". Further, the voice recognition data "Billie Joel" is converted into the data table DTBL.
Using TOC data TOCD, in this case, data "CC
CC ”.

Subsequently, the first C
D is taken out and set at the playback position, and the T
The OC data is read. Then, the read TOC data is compared with the TOC data “CCCC” converted by the data table DTBL, and if they do not match, the second CD in the CD storage 11 is next read. The same processing as in the case of the first CD is performed.

In this manner, the CDs in the CD storage unit 11 are sequentially taken out one by one, and the TOC data is compared with the TOC data converted by the data table DTBL. This process is repeated.

If the two data match, the CD at the playback position at this time has the TOC data "CC
CC ", and this data is the TOC data of the CD when" Bill Joel "is uttered in [Register CD]. Therefore, at this time, the CD at the playback position is nothing but the CD at the time of registration by uttering "Billy Joel" by voice. That is, the target CD.
Then, since the CD 12 is at the reproduction position, the reproduction key is operated thereafter to start reproduction of the CD 12.

Thus, according to this CD changer,
When a singer's name or the like is instructed by voice, a CD in which the singer's name or the like is registered is selected from the CD storage unit 11 and set at the playback position.
Even if a large number of CDs are stored in the
There is no need to remember the number of the stored CD in the stored CD. Alternatively, it is not necessary to repeat the key operation as described in the items (1) and (2) until a CD for the purpose is found. Therefore, a target CD can be easily selected.

Further, the data of the TOC of the CD and the data of the result of the speech recognition are prepared as a data table DTBL, and a target CD is prepared by using the data table DTBL.
Is selected, the data table DTBL is valid even if the order of the CDs in the CD storage unit 11 is changed. Therefore, for example, when selecting the CD in the CD storage unit 11 by key operation, this is easy. Thus, even if the CDs are rearranged in a specific order, there is no need to re-register the name of the singer who designates the CD.

In the above description, if the storage position when the CD is stored in the storage section 11 and the data as a result of the voice recognition are prepared in the data table DTBL, the C to be reproduced by voice is obtained.
When D is specified, the storage position of the corresponding CD can be specified by the voice recognition data. Therefore, the target CD can be immediately moved from the storage unit 11 without checking the TOC of the CD stored in the storage unit 11. Can be taken out and played.

[0033] Some FM broadcasting stations in Europe provide an RDS service. In this RDS service, an identification code of a broadcasting station called a PI code is multiplexed into an original program. Since the transmission is performed, the PI code and the data of the result of the speech recognition of the broadcast station name are prepared in the data table DTBL, and when the broadcast station name is generated, the corresponding broadcast station can be selected.

Further, in the example of FIG.
The designation and stop of the reproduction track can also be controlled to those states using the recognition result of the speech recognition circuit 25. In the above description, the case of a CD changer is used.
The present invention can also be applied to an MD changer that selects and plays back.

[0035]

According to the present invention, even when a large number of disks are stored in the storage section, it is not necessary to remember the number of the target disk. Alternatively, it is not necessary to repeat the key operation as described in the paragraphs (1) and (2) until a target disk is found. Therefore, a target disk can be easily selected. Also, even if the order of the disks in the storage unit is changed, it is not necessary to re-register the keywords.
