DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sample listening device for a song with a model singing sound, and more specifically, a song with a model singing sound which is the original song of a karaoke song by a user through a connected telephone line. The present invention relates to a telephone listening service apparatus for providing a service for listening to a telephone.

[0002]

2. Description of the Related Art Conventionally, in order to listen to music, a listening device such as a CD player, which is installed in a store or the like and in which a new music CD or the like is set in advance, is used. The user operates the listening device and listens to the song with headphones.
Alternatively, the user listens to the music by inputting the required amount of money into the Dukebox and playing the desired music.

[0003]

For the karaoke user, the trial listening is to memorize or confirm a song to be sung. In-store listening devices are mainly installed to promote new songs. Therefore, it is almost impossible to listen to songs other than new songs. Playing until you learn the songs in the Dukebox is expensive, and it's a waste of time to just check them and play them. So, TV
And radio programs, and actively watch song programs. However, regardless of new songs or recent hit songs, old songs can only be expected from date programs that are broadcast only occasionally. Moreover, the desired song is not always played on air. For a minor song, the chance is near zero. Therefore, it is necessary to buy software such as a CD or to record the music from a rental CD on a cassette tape or the like so that the music can be reproduced at any time.

[0004] Further, as a karaoke user, the true intention is to check the correct singing style or the like immediately before singing, and then to wish for the actual performance. Certainly, there are ways to use a portable CD player or cassette tape player, but in reality there are far more songs that say "I don't want to buy a CD, but I want to sing at karaoke." Moreover, the part of the song that you want to sing is often only a small part of the whole song. It's a waste of money to buy a lot of expensive CDs for songs you only listen to a little. Even if it is a cassette tape, it is troublesome considering the time and effort of recording, and the rental CD fee alone can be quite large. In addition, it is not always the case that karaoke is known in advance, but rather karaoke is often used depending on the situation. Always a portable C for karaoke
You can't just carry a D player or cassette tape player. In addition, since the song to be sung is not limited to one song, CDs and cassette tapes for a plurality of songs must be prepared. This means that you must always carry bulky luggage. Furthermore, checking a song you sing without listening to other people's songs at the karaoke hall could be rude to your companion and make the venue empty.

[0005] On the other hand, there is also a singer who wants to secretly audition and check the correct singing method, and want to behave as if he / she is used to singing in actual production. Doing so will make you happy, and the place will be exciting. For that purpose, it is necessary to be able to easily perform a music selection operation regardless of a place or time and to quickly listen to only a desired portion.

Accordingly, an object of the present invention is to eliminate the need to carry extra equipment and software, to select a model song to be sampled by simple operation when necessary, to quickly search only the desired portion, and to reduce the cost. The aim is to achieve a listening device that can be used at a reasonable price.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a telephone preview service apparatus for transmitting a song with a model singing sound to a connected telephone line. It has a data storage unit, an automatic response unit, and a DTMF signal decoding unit, and the main control unit controls these components to control the telephone preview service device.

[0008] The data storage means stores a large number of music information with model singing sound, which is the original song of the karaoke music. Is managed as a key. When the automatic answering unit receives a call from the telephone line network, it connects the line and sends out a voice message for guiding a request number input method and various operation input methods to the line. The DTMF signal decoding means operates upon receiving a DTMF signal from a connected line, recognizes the content of the DTMF signal, and transmits the request number and various operation signals to the main control unit.

When the main control section receives the request number from the DTMF signal decoding means, it calls and reproduces the corresponding song information with the model singing sound from the data storage means, and sends it out as an analog audio signal to the line. Further, in response to the operation signal, reproduction control such as fast-forward or fast-reverse is performed on the music piece with the model singing sound being reproduced.

[0010] More preferably, the main control unit performs information processing in a time-division manner and controls each of the constituent units in accordance with the timing of the information processing so that a telephone preview service can be simultaneously provided to a plurality of telephones. It is to be.
