Abstract

PROBLEM TO BE SOLVED: To realize a music retrieving device which automatically changes a key to a key signature suitable for singing of a person who has performed retrieval. SOLUTION: When a piece of music including a melody similar to an inputted melody is retrieved, the it is specified in which part of progress structure of the piece of music the melody is located, and the highest-pitched sound and the lowest-pitched sound of the song melody of the piece of music are obtained, and a CPU analyzes and calculates the most suitable singing range of the person who has inputted a voice, and the device discriminates the key (key signature) suitable for singing in this singing range, and music is played in this key.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a music retrieval apparatus for retrieving a song from voice input such as melody singing and performance, and reproducing a singing by accompaniment or synthetic voice.

[0002]

2. Description of the Related Art A conventional music search apparatus does not consider singing along with a music to be played by a searched person. Therefore, when music data in a storage device is played back, a user can automatically tune to a range where the user can easily sing. I couldn't play back with a key change. Therefore, when trying to sing along with the reproduced music, it was necessary to sing with a voice that deviated from his own range, and he could not comfortably sing or could not sing, and he had to change the key to his own range.

[0003]

As described above, the conventional music retrieval apparatus has a problem that the reproduction in accordance with the key of the user is not automatically performed. SUMMARY OF THE INVENTION It is an object of the present invention to realize a music search apparatus that automatically changes a key to a range suitable for a searched person to sing and plays the music.

[0004]

In order to solve the above problems, the present invention specifies which part of the melody is included in the progress of the tune when searching for a tune including a melody similar to the inputted melody. Then, the CPU calculates the highest note and lowest note of the melody of the song, and the CPU analyzes and calculates the optimal range for singing by the person who inputs the voice, and keys (key signature) suitable for singing in the range.
Is determined by the device, and the music is reproduced with the key.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a music search apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a diagram showing an embodiment of a music search apparatus according to the present invention. FIG. 2 is a flowchart of one embodiment.

First, the apparatus of the present invention performs initial settings at the time of system startup. FIG. 2 shows the process (1). The initial setting is performed while the present apparatus interacts with the user in an interactive manner. The apparatus asks the user for items necessary for the initial setting, and in response, the user speaks into the microphone [FIG. 1 (a)] or hums the melody, and the conversation proceeds. .

[0008] The voice input from the microphone (a) is digitized by A / D conversion (b) and is converted to a CPU (c).
Is output to If the audio data cannot be processed in the language or the pitch (for example, when a plurality of sounds are included), a re-input standby state is set.

As the microphone, a stand-alone microphone or a small and lightweight tie-pin type microphone is used when it is not desired to be conscious of the microphone.

[0010] Items required for the initial setting include "user personal information" such as gender and age, "music information on the background of the user" such as hometown, home school, favorite songs and nostalgic songs, and individual users. "Reproduction method" such as "quality of vocal cords" such as pitch range suitable for singing, setting of instrument type and volume for reproduction, presence / absence of vocals (lyrics), melody, presence / absence of harmony, and the like.

The "user personal information" necessary for the initial setting is used for sorting the search conditions.
A categorization for preferentially searching from the music information in D (e) is performed.

The "music information on the background of the user", which is necessary for the initial setting, is searched and output with priority given to the music information unique to the individual, and the necessary information is read from the CD-ROM (f).

The "quality of vocal cords" required for the initial setting is as follows.
This is information for reflecting the pitch of the music adapted to each user at the time of reproduction.

The "reproduction method" of the items necessary for the initial setting is as follows.
This is the setting when the user finally plays the music selected from the searched music.

The above initial setting information is registered and stored in a user database in the HDD (e). After registration, the user can proceed to the next search process without performing the initial setting as described above.

In the search process, if the data input by the user to the apparatus for search is a language, the phrase contains a proper noun such as a song title, a person's name, a place name, or the lyrics of the song. If so, the CPU (c) searches the text information in the plurality of music data recorded on the HDD (e) for a match.

If the input data contains a melody, the CPU (c) searches for a piece that matches or is similar to the melody information of the music data in the HDD (e). Then, an appropriate key for the user to sing the searched and extracted music is calculated.

In FIG. 2D, the search result can be presented to the user by a method such as display on a display device [FIG. 1G], braille display, bone conduction, and the like. Or, it is made into a language by D / A conversion (d) and output from the speaker (h). There is also a method called announcement with synthesized voice by a humanoid robot.

Since all songs that match the search conditions and songs that include a melody similar to the sung melody are extracted, a plurality of songs may be extracted. Various data such as song name, singer name, composer name, genre category, presentation time, production time / period, lyrics, etc. of each extracted music data are used as auxiliary means to find the music that the user wants to play from among them Is presented in the manner described in the previous section. The item of data to be presented can be selected by the user.

In response to the search result presented as described above, the user selects a tune by voice input such as "~ tune." Or "this", button operation, keyboard input, or the like. Can be.

In response to this, the CPU plays the selected music. This is the process of FIG. here,
The data of the selected music is read from the HDD (e),
According to the setting of the reproduction method set in the initial setting, the instrument sound, melody and lyrics are D / A converted (d) and output from the speaker (h). Performance is MI of standard MIDI file
This is performed by reproduction with a DI sound source, and the robot sings with synthetic voice in synchronization with the performance. The synthesized speech can be played with a monotonous robotic character without fluency and inflection, or with fluent and natural pronunciation, and can be adjusted to taste. In the former case, you can enjoy a unique fun.

The music and settings selected by the user and the personal information of the user are recorded in the database of the HDD (e) provided in the apparatus, and the records are referred to when the apparatus is used again. The question content from the device is optimized for each user.

It is also possible to synchronize a plurality of robots with a chorus and make them sing, to imitate a performance, and to imitate a chorus group or band. For example, in the case of playing Cool Five's “Nagasaki was raining today”, the robots 1 to 5 sing the chorus part “Wawa Wawa”, and the robot 6 sings the main vocal part with the unique moderation of Maekawa Kiyoshi.

[0024]

As described above, in the music search and performance apparatus of the present invention, means for searching for a song based on the input of a song or performance sound and automatically adjusting the searched song to a key that is easy for the search user to sing. The means and the means by which the apparatus accompanies with automatically adjusted keys or sings with synthesized voice allow the user to smoothly search for music in conversation with the robot and enjoy a song or performance.
