However, since the supporter needs to give guidance to the trainer in the training method of non-patent document 1, it is necessary to adjust the training schedule with the supporter, and there is a problem that the training is time-constrained. It was. Also, in training, there is a problem that psychological resistance exists because other people listen to the singing voice.
The utterance evaluation apparatuses of Patent Documents 2 and 3 have a problem that they are not suitable for improving sensation even if training of the utterance method in which the voice is mixed with the back voice can be used. In training on vocalization, there was a limit to the improvement of speech.

  The present invention has been made paying attention to such a conventional problem, and the trainer can freely train without being restricted by time and listening to the singing voice by others. It is an object of the present invention to provide a sound improvement training apparatus and a sound improvement training program with high improvement effects.

In order to achieve the above-mentioned object, a senile improvement training apparatus according to the present invention includes a reference sound output means for outputting at least a reference pitch sound, a voice input means for inputting a trainee's voice, and the voice input. The pitch detection means for obtaining the pitch of the voice input to the means, and the pitch of the sound output from the reference sound output means and the pitch obtained by the pitch detection means are compared to match the pitch or Pitch matching means for judging pitch mismatch and pitch match recognized by the trainee by comparing the pitch of the sound output from the reference sound output means with the pitch of the voice uttered by himself Alternatively, a recognition input unit that receives an input of pitch mismatch and outputs the pitch match or pitch mismatch input as a recognition signal to a recognition determination unit; a determination of the pitch determination unit; and a recognition signal of the recognition input unit And match or fail to recognize A recognition judgment means for judging a match, and an answer output means for outputting a correct answer signal for notifying a correct answer or an incorrect answer signal for notifying an incorrect answer when the recognition judgment means judges the recognition match or the recognition mismatch. It is characterized by.

The senile improvement training program according to the present invention provides a computer with reference sound output means for outputting at least a reference pitch sound, voice input means for inputting a trainee's voice, and voice input to the voice input means. A pitch detection means for obtaining a pitch, a pitch for judging pitch match or pitch mismatch by comparing the pitch of the sound output from the reference tone output means with the pitch obtained by the pitch detection means Judgment means, a trainee accepts an input of pitch match or pitch mismatch recognized by comparing the pitch of the sound output from the reference sound output means and the pitch of the voice uttered by himself, A recognition input unit that outputs the pitch match or pitch mismatch input as a recognition signal to the recognition determination unit, and a recognition match or a recognition mismatch by comparing the determination of the pitch determination unit with the recognition signal of the recognition input unit To judge When the determination means and the recognition determination means determine the recognition match or the recognition mismatch, the determination means and an answer output means for outputting a correct answer signal notifying a correct answer or an incorrect answer signal notifying an incorrect answer are functioned. .

  According to the tonal improvement training apparatus and the tonal improvement training program according to the present invention, the trainee speaks according to the pitch of the reference sound, and inputs the recognition of whether the reference sound matches the pitch or the pitch mismatch. Thus, it can be confirmed whether or not the recognitions are matched by the correct signal. Alternatively, the trainee utters at a different pitch with respect to the pitch of the reference sound, inputs the recognition of the pitch mismatch with the reference sound, and confirms whether the recognition matches with the correct signal May be. This internal feedback can effectively improve the sense of sound. Moreover, since one person can train, the trainer can freely train without being restricted by time and without being sung by others.

  In the present invention, the reference pitch sound is preferably composed of the same type of sound as a human voice. The voice input means may be composed of two or more. For example, the voice input means may include two or more microphones that allow two or more trainees to input voices separately at the same time. The answer output means preferably outputs an incorrect answer signal notifying an incorrect answer when the recognition determining means determines that the recognition does not match. The pitch coincidence determined by the pitch judging means may include a high pitch and a low pitch within a predetermined pitch range from the reference pitch, in addition to the case where the pitches completely match. Good. For example, a pitch difference smaller than 2 degrees may be set so as to be determined as pitch matching.

  The recognition input means may adopt a keyboard, a mouse, a touch sensor, a microphone, a remote controller including a three-axis acceleration sensor for detecting a change in tilt or movement, or any other input method. The correct answer signal output by the answer output means may be a sound output from a speaker, an image displayed on a monitor, vibration of a vibrator, or any other output signal. The answer output means may indicate a motion linked to a hand by a remote controller provided with a three-axis acceleration sensor that detects a change in inclination or motion as an image on a monitor.

In the present invention, the reference sound output means may output two or more continuous sounds having the same or different pitches.
In this case, since training to utter in accordance with the pitch of two or more consecutive sounds can be performed, a higher sound improvement effect can be obtained. Two or more sounds having different pitches may have a pitch smaller than a minor second or a larger pitch.

In the present invention, the reference sound output means may simultaneously output two or more sounds having the same or different pitches.
In this case, since the training can be performed in accordance with the pitch of two or more sounds that are output simultaneously, the effect of improving the sensation is higher. Two or more sounds having different pitches may have a pitch smaller than a minor second or a larger pitch.

  When the pitches of two or more simultaneously output sounds are different from each other, the pitch determining means includes the pitches of two or more sounds output from the reference sound output means and the pitch detecting means. When the obtained pitch is compared with the obtained pitch and the pitch obtained by the pitch detecting means coincides with any one of the two or more sounds outputted from the reference sound output means, Even if it is determined, the pitch of two or more sounds obtained by the pitch detection means from the voice input to the voice input means at different times is output from the reference sound output means. Even if it is determined that the pitch matches when all the pitches of two or more sounds match, the pitch obtained by the pitch detection means is equal to or more than two sounds output from the reference tone output means. If the pitch matches the highest or lowest pitch, the pitch matches. It may be.

  In the present invention, the pitch detection means obtains the pitch of the voice input to the voice input means and the duration of the same pitch, and the pitch determination means determines the sound output from the reference sound output means. May be compared with a pitch having a duration of the same pitch obtained by the pitch detection means for a predetermined time or more to determine pitch match or pitch mismatch.

  In this case, if the voice is not uttered so that the duration of the same pitch is equal to or longer than the predetermined time, it will not be judged that the pitch matches, so the voice will be conscious of the pitch naturally, and the correct signal will be output by coincidence. Can be prevented. In this way, since training can be performed with particular attention to the pitch, a higher tone improvement effect can be obtained. The duration of the same pitch is, for example, 3 seconds, but it may be shorter or longer.

In the present invention, the answer output means increases the volume of the sound output from the reference sound output means when the determination of the pitch determination means matches the recognition signal output from the recognition input means. May be output as a correct answer signal.
In this case, it is possible to know the correct answer of the pitch by increasing the volume of the sound output from the reference sound output means, so that the correct answer can be recognized, and a higher sound improvement effect can be obtained. it can.

In the present invention, the reference sound output unit may output a sound having a pitch obtained by the pitch detection unit when the recognition determination unit determines that the recognition does not match.
In this case, since the sound of the pitch of the trainee's voice input to the voice input means is output from the reference sound output means, it is possible to be aware of the pitch that he / she uttered, and to obtain a higher sound improvement effect be able to. It is preferable that the type of sound output from the reference sound output means can be arbitrarily set such as a human voice or a piano sound.

In the present invention, the reference sound output means outputs a sound having a pitch different from the pitch of the reference sound and the pitch obtained by the pitch detection means when the recognition determination means determines that the recognition does not match. It may be output.
In this case, the pitch of the reference sound and the pitch of the pitch that is different from the pitch of the trainee himself can be strongly conscious of the pitch of the utterance, and a higher tone improvement effect can be obtained. .

In the present invention, the reference sound output means may be able to output a sound having a pitch obtained by the pitch detection means.
In this case, first, the trainee can input a voice having an arbitrary pitch to the voice input means, and the reference sound output means can output a pitch sound such as the voice of the trainee.

  According to the present invention, a trainer can freely train without being restricted by time and without listening to a singing voice by another person. A program can be provided.

It is a block diagram which shows the structure of the sound improvement training apparatus of embodiment of this invention. It is a flowchart which shows the process sequence of the sound improvement training apparatus shown in FIG.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a tonal improvement training apparatus according to an embodiment of the present invention. In addition, the sound improvement training apparatus according to the embodiment of the present invention can be executed by a computer using a computer-readable recording medium such as a hard disk, a CD-ROM, a memory stick, or a flexible disk in which the sound improvement training program is recorded.

As illustrated in FIG. 1, the computer includes a main control unit 10, an input unit 20, a calculation determination unit 30, an output unit 40, and a storage unit 50.
The main control unit 10 is composed of a CPU and the like, and performs control of each unit, data transfer, various calculations, and the like.

  The input unit 20 includes a voice input unit 21 and a recognition input unit 22. The voice input means 21 has a microphone and inputs a trainee's voice. The recognition input means 22 has a keyboard, inputs a pitch match or pitch mismatch recognition, and outputs a pitch match or pitch mismatch recognition signal. For example, the input for recognizing the pitch match can be performed by operating the keypad “1”, and the input for recognizing the pitch disagreement can be performed by operating the keypad “0”. The input of recognition of pitch mismatch may indicate whether the pitch of the trainee's voice is higher or lower than the reference pitch.

  The output unit 40 includes reference sound output means 41 and answer output means 42. The reference sound output means 41 has a speaker and outputs a selected type of sound, for example, a sound having a reference pitch with a human voice. The reference sound output means 41 can also output two or more continuous sounds having the same or different pitches. The reference sound output means 41 can simultaneously output two or more sounds having the same or different pitches.

  The calculation determination unit 30 is composed of a CPU or the like, and includes a pitch detection means 31, a pitch determination means 32, a recognition determination means 33, and a time measurement means 34. The pitch detection means 31 has a frequency measuring device, and obtains the pitch of the voice input to the voice input means 21. The pitch determination unit 32 compares the pitch of the sound output from the reference tone output unit 41 with the pitch obtained by the pitch detection unit 31 to determine whether the pitch matches or does not match, and determines the determination result as an electric signal. Is output.

  If the recognition input means 22 can input whether the pitch of the trainee's voice is higher or lower than the reference pitch as recognition of pitch mismatch, the pitch determination means 32 By comparing the pitch of the sound output from the reference sound output means 41 with the pitch obtained by the pitch detection means 31, the pitch obtained by the pitch detection means 31 is output from the reference sound output means 41. If the pitch matches the pitch of the output sound, it is determined that the pitch matches.If the pitch is higher than the pitch of the output sound, it is determined that the pitch is high, and if the pitch is lower than the pitch of the output sound, It may be determined that the pitch is low and pitch mismatch. The pitch determined to be pitch mismatch with respect to the reference pitch can be set as appropriate, and exactly one degree does not have to be the pitch match.

  The pitch determination means 32 outputs two or more sounds from the reference sound output means 41 at the same time. If the pitches of the sounds are different from each other, the pitch determination means 32 outputs two or more sounds output from the reference sound output means 41. Is compared with the pitch obtained by the pitch detection means 31, and the pitch obtained by the pitch detection means 31 is any one of two or more sounds output from the reference sound output means 41. It is determined that the pitch matches when the pitch matches. Alternatively, the pitches of two or more sounds obtained by the pitch detecting means 31 from the voices input to the voice input means 21 at different times are all the two or more sounds output from the reference sound output means 41. It can also be set to determine that the pitch matches when the pitch matches. Further, when the pitch obtained by the pitch detection means 31 matches the highest pitch or the lowest pitch among the two or more sounds output from the reference pitch output means 41, it is determined that the pitch matches. Can also be set.

The recognition determination unit 33 compares the determination of the pitch determination unit 32 with the recognition signal of the recognition input unit 22 to determine recognition match or recognition mismatch, and outputs the determination result as an electric signal.
When the recognition input unit 22 can input whether the pitch of the trainee's voice is higher or lower than the reference pitch as recognition of pitch mismatch, the recognition determination unit 33 The determination of the pitch determination means 32 and the recognition signal of the recognition input means 22 are collated. When the pitch determination means 32 is a pitch match determination and the recognition input means 22 is a pitch match input, the pitch is When the judgment means 32 is a judgment of pitch mismatch with a high pitch, the recognition input means 22 is a pitch mismatch input higher than the pitch, and the pitch judgment means 32 is a judgment of pitch mismatch with a low pitch, When the recognition input means 22 inputs a pitch mismatch that is lower than the pitch, it is determined as a recognition match. Otherwise, it is determined as a recognition mismatch and the determination result is output as an electrical signal.
The time measuring means 34 calculates the duration of the same pitch or the duration of the same pitch above a predetermined volume.

  The reference sound output means 41 can also be set to output the sound of the pitch obtained by the pitch detection means 31 when the recognition determination means 33 determines that the recognition does not match. The reference sound output means 41 outputs a sound having a pitch different from the pitch of the reference sound and the pitch obtained by the pitch detection means 31 when the recognition determination means 33 determines that the recognition does not match. It can also be set.

  The answer output means 42 has a speaker and a monitor, and outputs a correct answer signal informing the correct answer when the recognition judging means 33 judges that the recognition coincides. When the judgment by the pitch judgment means 32 and the recognition signal output from the recognition input means 22 match, the answer output means 42 increases the volume of the sound output from the reference sound output means 41 to obtain a correct answer signal. It can also be output.

  The storage unit 50 includes a hard disk memory, and includes a reference sound storage unit 51 and a voice storage unit 52. The reference sound storage means 51 is a training that is input from the sound of the reference pitch, which is a little different pitch or a different kind of sound, for example, female voice, male voice, voice input means 21. A lot of people's voices, dog calls, piano sounds, etc. The reference sound storage means 51 stores the types of voices such as female voices and male voices and various pitches, and the voices selected from the stored voice types and the various pitches stored. The selected pitch may be synthesized and output from the reference sound output means 41.

  The voice storage unit 52 stores the trainee's voice input to the voice input unit 21 in association with the sound output from the reference sound output unit 41. The trainee's voice stored in the voice storage unit 52 can be output from the reference sound output unit 41 together with the sound output from the reference sound output unit 41 and reconfirmed.

  Next, referring to the flowchart of FIG. 2, a processing procedure of the phonetic improvement training apparatus will be described.

  When the process is started by the computer (step 61), the reference sound output means 41 selects a sound (for example, a reference pitch) stored in the reference sound storage means 51 based on a preset condition (for example, , "Do" sound) is output as a human voice (step 62). The trainee utters at a pitch that matches the pitch of the “do” of the sound output from the reference sound output means 41 and inputs it to the voice input means 21 (step 63). The pitch detection means 31 obtains the pitch of the voice input to the voice input means 21 (step 64).

  The pitch determination unit 32 compares the pitch of the sound output from the reference tone output unit 41 with the pitch obtained by the pitch detection unit 31 to determine whether the pitch matches or does not match, and determines the determination result as an electric signal. (Step 65). The trainee compares the pitch of the sound output from the reference sound output means 41 with the pitch of the voice he / she uttered, and inputs recognition of pitch match or pitch mismatch using the keyboard (step 66). ).

  The recognition determination unit 33 receives the electrical signal of the determination result from the pitch determination unit 32, and compares the determination of the pitch determination unit 32 with the recognition signal of the recognition input unit 22 to determine recognition match or recognition mismatch, The determination result is output as an electric signal (step 67). For example, if the pitch of the reference sound matches the pitch of the trainee's voice, and if the trainee also inputs a pitch match recognition, it is determined that the match is a recognition match. In addition, when the pitch of the reference sound and the pitch of the trainee's voice do not match, when the trainee also inputs the recognition of the pitch mismatch, it is determined that the recognition matches. If it is determined that the recognition matches, the answer output means 42 outputs a correct answer signal (step 68) and the process ends (step 69).

  If the pitch of the reference sound and the pitch of the trainee's voice do not match, and if the trainee inputs the pitch match recognition, it is determined that the recognition does not match. In addition, when the pitch of the reference sound matches the pitch of the trainee's voice, if the trainee inputs the recognition of the pitch mismatch, it is determined that there is a recognition mismatch. If it is determined that the recognition does not match, the reference sound output means 41 outputs a new pitch and repeats the process.

  In this way, according to the senile improvement training device, the trainee utters in accordance with the pitch of the reference sound, inputs the recognition of the pitch match or pitch mismatch with the reference sound, and based on the correct answer signal It is possible to confirm whether or not the recognitions match. This internal feedback can effectively improve the sense of sound. Moreover, since one person can train, the trainer can freely train without being restricted by time and without being sung by others.

  When the recognition determining unit 33 determines that the recognition does not match (step 67), when the reference tone output unit 41 outputs the sound of the pitch obtained by the pitch detection unit 31, the voice input unit 21 Since the sound of the pitch of the trainee's voice input to is output from the reference sound output means 41, the pitch uttered by himself / herself can be recognized, and a higher sound improvement effect can be obtained.

  When the recognition determining unit 33 determines that the recognition does not match (step 67), the reference tone output unit 41 generates a tone having a pitch that is different from the pitch of the reference sound and the pitch obtained by the pitch detecting unit 31. When output, the pitch of the sound that is different from the pitch of the reference sound and the pitch that the trainee himself uttered can be strongly conscious of the pitch that was uttered, and higher sound improvement An effect can be obtained.

  When the reference tone output means 41 outputs two or more consecutive sounds with the same or different pitches (for example, a “do” sound and a “le” sound) in the sound improvement training device. (Step 62) Since training can be performed in accordance with the pitch of two or more consecutive sounds, a higher sound improvement effect can be obtained. As the two or more continuous sounds, a combination of a pitch of 2 degrees or more, a pitch of 2 degrees, and a perfect 1 degree (same pitch) is preferable.

  When two or more sounds having the same or different pitches are simultaneously output to the reference sound output means 41 (step 62), training to speak in accordance with the pitches of two or more simultaneously output sounds Can improve the sense of sound. As a sound output two or more sounds at the same time, a combination of a pitch of 2 degrees or longer, a pitch of 2 degrees, and a perfect 1 degree (same pitch) is preferable.

  Further, when the answer output means 42 matches the judgment of the pitch judgment means 32 and the recognition signal output from the recognition input means 22, the volume of the sound output from the reference sound output means 41 is increased and the correct answer signal is output. (Step 68), it is possible to know the correct answer of the pitch by increasing the volume of the sound output from the reference sound output means 41, so that the correct pitch can be recognized, A higher sound improvement effect can be obtained.

  In the tonal improvement training device, the pitch detection means 31 may be set so as to obtain the pitch of the voice input to the voice input means 21 and the duration of the same pitch based on the measurement value of the time measurement means 34. Good (step 64). In this case, the pitch determination means 32 is equal to or longer than a predetermined time (for example, 3 seconds or more) for the duration of the same pitch obtained by the pitch detection means 31 and the pitch of the sound output from the reference sound output means 41. Are compared with each other to determine whether the pitch matches or does not match (step 65).

  In such a configuration, if the utterance is not uttered so that the duration of the same pitch is equal to or longer than the predetermined time, it is not determined to match the pitch, so the utterance is naturally conscious of the pitch, and by chance, the pitch matches and the correct answer A signal can be prevented from being output. In this way, since training can be performed with particular attention to the pitch, a higher tone improvement effect can be obtained.

  In the tonal improvement training device, the pitch detection means 31 calculates the pitch of the voice input to the voice input means 21 based on the measurement value of the time measurement means 34, the volume, and the duration of the same pitch above a predetermined volume. It may be set as required (step 64). In this case, the recognition input means 22 is a sound that the trainee's voice is output from the reference sound output means 41 when the duration of the same pitch above the predetermined volume obtained by the pitch detection means 31 is longer than a predetermined time. It is also possible to output a pitch coincidence recognition signal indicating that the pitch coincides with (step 66).

  In this case, if the voice is not uttered so that the duration of the same pitch equal to or higher than the predetermined volume is equal to or longer than the predetermined time, it is not determined that the pitch matches, so the voice is naturally conscious of the pitch and volume. It is possible to prevent the correct answer signals from being output in agreement. In this way, since training with particular attention to pitch and voice volume can be performed, a higher sound improvement effect can be obtained.

  The sound improvement training device may be used by being incorporated in a computer game machine, a karaoke device, a multi-function mobile phone, a car stereo device, a personal computer, or the like.
