Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a karaoke apparatus, and particularly to an improvement of a karaoke apparatus that calculates a user's voice evaluation for an accompaniment piece and notifies a voice synthesized sound corresponding to the evaluation.

Conventionally, there is a language training machine as disclosed in Japanese Patent Application Laid-open No. 56-144477, as a device for notifying the analysis result of a user's voice pattern with respect to a reference voice pattern using a synthesized voice. Considering the purpose of language practice, this conventional device has a function to analyze and compare the user's voice pattern and a reference sound pattern.
There is no function to store the analysis and comparison results, and when the user's voice is input, it is immediately analyzed and the comparison results are successively announced.

Therefore, such conventional techniques cannot be applied to karaoke machines. In a karaoke device, the user must evaluate the entire accompaniment piece, but this is not possible if the device does not have a memory function for comparison results, such as the language training device described above.

It is conceivable that the above-mentioned language training machine has a memory in the user's voice pattern analysis section, but even in that case, when applied to a karaoke device, the voice for all accompaniment pieces would have to be stored in memory. As a result, the memory capacity becomes enormous, leading to increased costs and lack of practicality. Moreover, since the pattern analysis section is located before the pattern comparison section, even if a memory is provided as a karaoke device, the comparison will only start after the playback of one accompaniment song is completed.
It takes time to notify the evaluation. It is natural for the user to want to know the evaluation of his/her own singing performance immediately upon completion of the singing performance, and the above-mentioned prior art cannot satisfy this requirement.

Although it is not a karaoke device, there is a device known as a singing self-study device that contrasts the user's voice with the volume and pitch of a reference voice that serves as a model and displays the volume and pitch on the screen, for example, as disclosed in Japanese Patent Laid-Open No. 56-85773. has been disclosed. According to this device, the user can evaluate his or her own voice by looking at the display on the screen, but the device itself does not evaluate it.
It is impossible to apply such conventional technology to karaoke equipment. That is, since the conventional device is a self-study device, it does not have the function of comparing the user's voice with the reference voice, nor the function of storing the comparison results. Therefore, it is completely impossible for a karaoke apparatus to notify the evaluation at the end of an accompaniment piece.

The present invention provides a low-cost and practical karaoke device that has a function that the above-mentioned conventional technology does not have at all, that is, a function that allows the karaoke device itself to notify its evaluation with a synthesized sound at the end of one accompaniment piece. The main purpose is to

To explain the above purpose in more detail, the present invention not only has the functions of a normal karaoke device, but also evaluates the user's singing using the karaoke device, including the entire accompaniment song. To provide a karaoke device having a built-in means for selecting and notifying a synthesized sound corresponding to the evaluation.

In order to achieve the above-mentioned object, the present invention provides a playback device that plays back an accompaniment piece and a reference signal corresponding to the accompaniment piece, and a playback device that plays back an accompaniment piece and a reference signal corresponding to the accompaniment piece, and a playback device that plays back the accompaniment piece played by the device and the user's audio signal input from a microphone. In a karaoke apparatus, the audio signal is compared with a reference signal reproduced from the reproduction apparatus, and the difference between the two signals is determined. a comparator that generates a comparison signal according to a first memory; a first memory that stores the comparison signal throughout one accompaniment piece;
an arithmetic processing device that reads a comparison signal equivalent to one song from the first memory, performs arithmetic processing on the read signal and generates an evaluation value; a second memory that stores and holds a signal and selectively outputs the synthesized sound or a signal corresponding to the synthesized sound in accordance with the evaluation value; The gist of the present invention is that the synthesized sound or the signal corresponding to the synthesized sound outputted from the memory is configured to be input to the amplifier as an analog signal.

The present invention will be described below with reference to an embodiment shown in the drawings. In the illustrated embodiment, 1 is an 8-track tape playback device, 2 is a comparator, 3 is a random access memory, 4 is an arithmetic processing unit, and 5 is an arithmetic processing unit. 6 is a read-only memory, 6 is a synthesized sound generator, 7 is a microphone, 8 is a switch, 9 is an audio amplifier, and 10 is a speaker.

The conventional accompaniment sound L is recorded on the left channel of the 8-track tape played by the playback device 1, but the reference signal R, which is only a single tone and does not include the chord of the accompaniment sound, is recorded on the right channel. There is.

The user's voice signal from the microphone 7 is applied to the audio amplifier 9 together with the accompaniment sound L via the switch 8, reproduced by the speaker 10, and sent to the comparator 2 together with the reference signal R.

The comparator 2 compares this comparison signal with the pitch and rhythm of the user's voice, and the sampled and compared difference component signal is stored in the memory 3 until one song is completed.

When the song ends, the signal of the difference component corresponding to one song stored in the memory 3 at that time is sent to the arithmetic processing device 4, which processes the signal from the beginning of the song and generates an evaluation value. obtain.

The memory 5 stores, for example, signals for controlling about 10 types of synthesized sounds, and the synthesized sound control signal corresponding to the evaluation value is selected, and the synthesized sound generator 6 is activated by the signal. A speech synthesis analog signal corresponding to the evaluation value is generated.

An end signal is obtained from the right channel of the 8-track tape at the end of the accompaniment piece, and this signal causes the arithmetic processing unit 4 to switch the switch 8, and the voice synthesis analog signal is sent to the speaker 10 via the amplifier 9.
You can hear the evaluation results by voice.

As explained above, according to the present invention, at the end of one accompaniment piece, it is possible to announce the enhancement of all the accompaniment pieces using a synthesized sound suitable for the atmosphere of the place where the karaoke machine is used, so that the atmosphere of the place can be improved. The element of exciting play is added.

Moreover, in the present invention, the synthesized sound corresponding to the above evaluation is announced using the amplifier and speaker of the karaoke apparatus, so that cost increase is suppressed.

Furthermore, since the reference signal that serves as the basis for evaluation is obtained from the playback device together with the accompaniment music, no new memory is required for the reference signal, which also improves practicality.
