2. Description of the Related Art In a communication karaoke system, the following additional service functions are known. Assign a personal ID to each user. When the user comes to the store, the terminal acquires the user's personal ID by some method (described later). When a user selects and sings a song with a remote controller or the like, a song selection history of the user is automatically created in a storage unit of the terminal. The music selection history data file of each user created in the terminal is transferred to the host device at an appropriate communication opportunity with the host device. The host device collects music selection histories from a large number of terminals existing in a wide area, and centrally manages the music selection history using a personal ID as a key. This allows the same user to have different stores,
The histories of singing at different terminals are also collected as one music selection history in the host device.

The above-mentioned music selection history is utilized as follows. When the terminal recognizes the personal ID, the terminal sends the personal ID to the host device and retrieves the corresponding music selection history to the terminal. When the user requests the terminal to display the song list, the terminal displays the song selection history of the user on the display, and a user input for designating a specific song for the display of the song selection history. And make a performance reservation. According to this function, each user can easily display a list of songs he or she can sing, and easily select and request a song to be sung from the list.

[0004]

As a method for obtaining the personal ID described above, the personal ID of the user is directly input to a keyboard, or an ID card in which a unique ID is recorded is distributed to each user. Is set in a card reader for each service use opportunity. However, these methods are troublesome because the user must input a personal ID or set an ID card in a card reader every time the above-mentioned song list display service is used. It is not much different from typing the song number on the keyboard.

Recently, a personal remote controller in which a personal ID is registered is distributed to users, and a personal ID transmitted from the personal remote controller is received to identify the user. By using this, the user does not need to be conscious of the operation of recognizing the personal ID by the machine, and it is extremely convenient to link this with the display service of the personalized song list. However, since the personal remote controller is expensive, it is impractical to have all users own the personal remote controller, and in reality, only specific users such as regular customers can use it. . Another problem is that even if the user owns the personal remote controller, if he forgets it, he or she will not be able to receive the song list display service.

On the other hand, Japanese Patent Application Laid-Open No. Hei 9-146563 discloses a karaoke apparatus in which a user is specified by a voice print. In this karaoke apparatus, personal information of a user is managed in a database using voiceprint data as a key, and voiceprint data of a user who intends to use a service is extracted, and personal information of the user is searched based on the voiceprint data. It works. According to this, it is not necessary for the user to input a personal ID and to set an ID card each time, and no device such as a personal remote controller is required.

However, when the method described in this publication is applied to the above-described centralized management system of the music selection history in the communication karaoke system, the following serious problem occurs. That is, the number of users handled by the host device in the communication karaoke system may increase to millions, and the current technology accurately compares the voiceprint data of millions with the input voiceprint data. The process of identifying one person cannot be performed at a practical speed.

The present invention has been made in view of such circumstances, and has a communication karaoke performance in which a user can easily and smoothly use a service for displaying a song list based on a personalized music selection history in a communication karaoke system. The purpose is to provide a terminal.
