<1. Vocal conditioning method and vocal training method by approaching the oral cavity>

(1) The method according to the embodiment is a vocal conditioning method by approaching the oral cavity, and includes a first step of relaxing the muscles included in the suprahyoid muscle group from inside the oral cavity, and a second step of relaxing the tongue base from inside the oral cavity. A process may be provided.

The suprahyoid muscle group is a general term for the mylohyoid muscle, digastric muscle, stylohyoid muscle, and geniohyoid muscle. The suprahyoid muscles are among the hyoid muscles that connect to the hyoid bone and are located above the hyoid bone. The suprahyoid muscles form the floor of the mouth. The suprahyoid muscles connect the hyoid bone and the mandible and are responsible for elevating the hyoid bone and the floor of the mouth. Therefore, by relaxing the muscles included in the suprahyoid muscle group, the hyoid bone and the floor of the mouth can be easily raised and lowered, and the smooth raising and lowering of the hyoid bone and the floor of the mouth can be promoted. That is, the vertical range of motion of the hyoid bone and the floor of the oral cavity is expanded. By increasing the range of motion of the hyoid bone and the floor of the mouth, it becomes possible to greatly change the opening of the airway. Relaxing the muscles included in the suprahyoid muscle group can be achieved, for example, by stimulating the floor of the mouth. Furthermore, since the tongue is supported by the floor of the oral cavity, when the floor of the mouth tends to rise and fall, the tongue also tends to rise and fall. Note that in the first step, it is sufficient to relax at least one muscle included in the suprahyoid muscle group.

The base of the tongue is the back side of the tongue. The base of the tongue generally covers the posterior third of the tongue. The base of the tongue is connected to the arch-shaped palatine arch at the back of the throat. By loosening the base of the tongue, the muscles that form the palatoglossal arch also relax, making it easier for the palatoglossal arch to expand, allowing the airway to widen. Loosening the tongue base can be achieved, for example, by approaching the tongue base with an insert inserted between the back of the tongue and the floor of the mouth. The insert loosens the base of the tongue.

When the hyoid bone and floor of the mouth become easier to elevate and descend, it has a positive effect on speech production. In addition, by relaxing the suprahyoid muscle group and the base of the tongue, changes in the opening of the airway are smoothed and the airway opens more easily, resulting in good vocalization. In addition, the elevation and descent of the tongue also affect vocalization, so if the floor of the mouth becomes easier to elevate and descend, and the tongue supported by the floor of the mouth also becomes easier to elevate and descend, good vocalization will be achieved. .

Furthermore, by relaxing the floor of the mouth and the base of the tongue, it can also be expected that the superior pharyngeal constrictor muscles that continue backward from the floor of the mouth and the base of the tongue will be relaxed. Relaxation of the superior pharyngeal constrictor muscles allows the airway to open.

Here, "relax" means relaxing the muscles. Relaxing the muscles promotes smooth muscle movement. For example, by applying external stimulation to a muscle, it is possible to relax the muscle. The stimulation given to the muscles is given by, for example, a pressing body. The pressing body may be an instrument such as an oral cavity pressing tool, or may be a human finger (for example, a finger pad). You can also relax your muscles by intentionally moving them and stretching them.

(2) The method according to the embodiment is a vocal conditioning method by approaching the oral cavity, and may include a first step of approaching the floor of the oral cavity and a second step of approaching the base of the tongue.

In the first step, as an approach to the floor of the oral cavity, by repeatedly pressing the floor of the oral cavity downward in the oral cavity, the muscles included in the suprahyoid muscle group are repeatedly compressed and released (or pressure reduced). may include causing. By pressing downward on the floor of the mouth, the suprahyoid muscle group can be compressed. The downward pressing is performed, for example, by applying the tip of an instrument such as an oral cavity pressing tool inserted into the oral cavity to the floor of the oral cavity and pushing the instrument downward. It is preferable that the pressure is strong enough not to cause pain. By releasing or reducing the downward pressure, the compression is released or reduced. Releasing or reducing the downward pressure is, for example, an upward movement of the instrument. Preferably, the oral cavity pressing tool includes a head provided at the tip and a handle extending rearward from the head. Preferably, the head has a shape that resembles a human finger (for example, a finger pad). In this case, by grasping the handle and pressing the floor of the oral cavity, an approach similar to pressing the floor of the oral cavity with a human finger can be realized.

By repeatedly pressing the floor of the oral cavity downward, the muscles included in the suprahyoid muscle group are repeatedly compressed and released, and the floor of the mouth can be effectively loosened. Repeating the downward pressing means, for example, moving the oral cavity pressing tool up and down a plurality of times. Since the floor of the oral cavity has a certain extent, in order to loosen the entire floor of the oral cavity, it is preferable to press at multiple locations on the floor of the oral cavity. Pressing of the floor of the oral cavity is preferably performed first on the front side of the floor of the mouth out of multiple places on the floor of the mouth, and then on the back side (back side) of the floor of the mouth. . Since the back side of the oral cavity may be sensitive, it is preferable to gradually shift the pressure point from the front side to the rear side. In addition, after pressing the location on the rear side of the floor of the oral cavity, pressing may be performed again on the location on the front side of the floor of the oral cavity, and the pressing location may be repeatedly shifted back and forth. Moreover, it is preferable that the pressure is applied to both the left side and the right side of the floor of the oral cavity.

The downward pressing of the floor of the oral cavity is preferably performed against at least one of the mylohyoid muscle and the geniohyoid muscle, and more preferably against the mylohyoid muscle. The mylohyoid muscle and the geniohyoid muscle are muscles that can be easily approached from within the oral cavity, so they are suitable targets for downward pressing.

The second step includes the 2-1 step of elevating the tongue base with an insert inserted between the back side of the tongue and the floor of the oral cavity as an approach to the tongue base, and the 2-1 step of lifting the tongue base between the back side of the tongue and the floor of the oral cavity. At least one of the steps 2-2, in which the insert is held in place with the insert inserted therebetween, and the tongue is moved forward so that the deep side of the oral floor presses the insert forward; It may include one step.

In step 2-1, the base of the tongue is forcibly raised relative to the floor of the oral cavity by the inserter. Elevation of the tongue base acts as a stimulus or stretch to the tongue base, thereby loosening the tongue base.

The insert can be inserted, for example, from the left side of the tongue, between the back of the tongue and the floor of the oral cavity. In this state, by tilting the insert upward to the right, the base of the tongue is lifted from the left side of the tongue. In this case, the left side of the tongue should be raised higher than the right side.

The insert can also be inserted from the right side of the tongue, between the back of the tongue and the floor of the oral cavity. In this state, by tilting the insert upward to the left, the base of the tongue is lifted from the right side of the tongue. In this case, the right side of the tongue should be raised higher than the left side.

Elevation of the tongue base may be performed only from either the left or right side, but by lifting the tongue base from both the left and right sides, the entire tongue base can be loosened. Note that the insert may be inserted from the front of the tongue.

Note that the insert used for elevating the base of the tongue can be the same as the pressing body used for pressing in the first step.

In step 2-2, the base of the tongue is stretched by moving the tongue forward. In other words, when a person autonomously moves their tongue forward with the tongue being inhibited from moving forward by the insert inserted between the back of the tongue and the floor of the mouth, the base of the tongue moves through the insert. The tongue moves forward while pressing forward. That is, as the tongue moves forward, the insert that remains between the back side of the tongue and the floor of the oral cavity presses the base of the tongue backward. This stretches the tongue base and loosens it. Furthermore, by moving the tongue forward, it also stretches the palato-lingual arch, which is connected to the tongue base, and loosens the palato-lingual arch. Step 2-2 is suitable for loosening the palatoglossal arch.

Preferably, the second step includes both the 2-1 step and the 2-2 step. The order of the 2-1st step and the 2-2nd step is particularly limited.The 2-1st step may be performed first, and the 2-2nd step may be followed, or the 2-2nd step may be performed first. Then, Step 2-1 may be left behind. However, it is more preferable to perform step 2-1 first and step 2-2 later. In step 2-1, by loosening the tongue base and moving the tongue with the tongue base loosened forward, the palato-lingual arch connected to the tongue base can be loosened more effectively.

Note that the order of the first step and the second step is not particularly limited, and the first step may be performed first and the second step later, or the second step may be performed first and the first step later. You may. However, it is more preferable to perform the first step first and the second step later. By performing the first step first without first performing the second step in which the sensitive area near the base of the tongue is approached, the floor of the oral cavity including the vicinity of the base of the tongue can be accustomed to the stimulation. By performing the second step after the area near the base of the tongue becomes stimulated, the second step can be performed smoothly.

<2. Examples of vocal conditioning methods and vocal training methods by approaching the oral cavity>

Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an example of a vocal conditioning procedure according to an embodiment. Vocal conditioning according to the embodiment is performed by approaching the oral cavity. In step S1 of FIG. 1, the suprahyoid muscle group is relaxed from within the mouth of the speaker (see images 101 and 102). Step S1 is the first step of approaching the floor of the oral cavity. Thereafter, in step S2, the base of the tongue is loosened (see image 103). Step S2 is the second step of approaching the base of the tongue.

Through steps S1 and S2, the suprahyoid muscle group and the base of the tongue can be relaxed to improve the vocalization condition. Therefore, good vocalization can be obtained by vocalizing after steps S1 and S2. For example, in voice training, performing step S1 and step S2 before vocalization allows for better vocalization and improves training efficiency. Incidentally, steps S1 and S2 may be performed by the speaker himself/herself performing a maneuver to approach the inside of the mouth, or by a person who supports conditioning performing a maneuver to approach the mouth of the speaker. may be implemented.

A voice speaker is, for example, a person whose job involves using the voice. A person who performs a job that uses voice is, for example, a vocalist, singer, voice actor, announcer, narrator, or presenter. The person who supports conditioning is, for example, a voice trainer.

In addition, in step S1 and step S2, the device described in Patent Document 1 (manufactured by Forest Co., Ltd., product name "Stretch Oral (registered trademark)") can be used as the device for approaching the oral cavity (oral pressing device). . This instrument includes a head provided at a distal end and a handle extending rearward from the head. In step S1, this instrument is used as an oral cavity pressing tool that presses the floor of the oral cavity with its head, and in step S2, it is used as an insert inserted between the back side of the tongue and the floor of the oral cavity. In step S2, the head of the oral cavity pressing tool presses the base of the tongue.

In step S1, the mylohyoid muscle shown in FIG. 2 is pressed by the tip (head) of the oral cavity pressing tool inserted into the oral cavity. The oral cavity pressing tool is inserted into the oral cavity with its handle erected as much as possible against the bone surface of the mandible (the floor of the oral cavity).

3 and 4 show the flow of operation of the oral cavity pressing tool in step S1. First, an oral cavity pressing tool is inserted into the front side of the floor of the oral cavity (near the back side of the lower front teeth), avoiding the tongue (step S301 in FIG. 3), and the front side of the floor of the oral cavity is pressed (step S302). In order to repeatedly apply pressure, the oral cavity presser is moved up and down within the oral cavity while being moved backward along the mylohyoid muscle while the oral cavity presser remains upright (steps S303, S304, S401, S402). This repeatedly presses the mylohyoid muscle from the front side to the back side (back side). As a result, the range from the anterior side to the posterior side of the mylohyoid muscle is stimulated by compression and release (or reduction of pressure) by pressing, and is relaxed.

Also, as shown in the images of steps S303, S304, S401, and S402, while pressing the floor of the oral cavity downward, the lower side of the mandible (lower side of the jaw) is pressed upward with a finger or the like from outside the oral cavity. As a result, stimulation by downward pressure is effectively applied to the floor of the oral cavity. In order to effectively apply stimulation, it is preferable that the point of upward pressure from the lower side of the mandible be near the extended position in the direction of downward pressure, as shown in FIG. It is preferable that the upward pressure from the lower side of the mandible similarly shifts from the front side to the rear side of the floor of the mouth as the downward pressure on the floor of the mouth shifts from the front side to the rear side of the floor of the mouth.

In step S1, the oral cavity pressing tool is moved to the rear side while pressing the floor of the oral cavity (steps S301 to S402), and when the oral cavity pressing tool reaches the innermost part of the floor of the oral cavity, as shown in FIG. The head of the oral cavity pressing tool (insertion body) is inserted between the back side of the tongue and the floor of the oral cavity (step S601).

Note that in FIG. 6, since a model without a tongue is used, the left hand of the operator holding the oral cavity pressing device (insertion body) in the right hand is shown as a "tongue". In FIG. 6, the range corresponding to the "tongue" is indicated by a white dotted line. In FIG. 6, the vicinity of the wrist of the left hand that resembles a "tongue" corresponds to the position of the "base of the tongue," and the palm of the left hand that mimics the "tongue" corresponds to the back side of the tongue. FIG. 6 shows a state in which the oral cavity pressing device is inserted from the left side of the tongue between the back side of the tongue and the floor of the oral cavity.

From the state of step S601, as shown in steps S602 and S603, by tilting the handle of the oral cavity presser upward slightly to the right, the base of the tongue is raised from the left side of the tongue (step S2 in FIG. 1: 2-1 step). By repeating the operation of raising and lowering the handle of the oral cavity pressing tool, the base of the tongue can be raised multiple times. By performing multiple lifts, the base of the tongue can be further loosened.

Note that FIG. 7 shows a state in which the base of the tongue is actually raised. In FIG. 7, the oral cavity pressing tool is inserted from the right side of the tongue between the back side of the tongue and the floor of the oral cavity, and the handle of the oral cavity pressing tool is tilted upward. In FIG. 7, the base of the tongue is raised from the right side of the tongue.

After the base of the tongue is raised in steps S601 to S603, the oral cavity pressing tool is returned to the state in step S601. That is, the base of the tongue is not elevated, and the oral cavity pressing device returns to the state where it is inserted between the back side of the tongue and the floor of the oral cavity.

Step S801 in FIG. 8 shows the state returned to step S601 in FIG. In addition, in FIG. 8 as well, the left hand of the operator holding the oral cavity pressing device (insertion body) in the right hand is shown as a "tongue".

In step S801 of FIG. 8, the oral cavity pressing tool (insert body) is in a state where the insert body is inserted between the back side of the tongue and the floor of the oral cavity. In this state, the oral cavity pressing tool is kept in place without being moved, and the person to be conditioned autonomously moves the tongue forward (step S802).

As shown in FIG. 8, when the tongue is moved forward in the oral cavity with its movement inhibited by the oral cavity pressing tool, the base of the tongue presses the insert member forward. As a result, the base of the tongue is stretched and loosened, and the palato-lingual arch (see Figure 9), which is connected to the tongue base, is stretched and the palato-lingual arch is firmly loosened (Step S2 in Figure 1: Step 2-2). . By repeating the back and forth movement of the tongue multiple times, the base of the tongue and the palatoglossal arch can be more effectively stretched.

In addition, if you move the tongue forward with the oral cavity presser (insert body) inserted from the left side and the right side of the tongue, the entire tongue base and palato-lingual arch can be stretched more effectively. be exposed.

<3. Experiment＞

Figures 10 and 11 show the results of conditioning experiments. In the experiment, the first group (hereinafter referred to as "Group A") and the second group (hereinafter referred to as "Group B") were given oral conditioning to the subjects before and after each group. The vocalizations were recorded, and the recorded sounds were analyzed.

There were 8 subjects in Group A: A1, A2, A3, A4, A5, A6, A7, and A8, and 8 subjects in Group B were B1, B2, B3, B4, B5, B6, B7, and B8. And so. Each subject in Group A and Group B was a student of the music department.

Oral conditioning for Group A and Group B was both performed using the device described in Patent Document 1 (manufactured by Forest Co., Ltd., trade name: Stretch Oral (registered trademark)).

The oral conditioning method for each subject in Group A was the "tongue approach." The method of "approaching the tongue" is described in "Revival from the Inside of the Mouth!" by Moriaki, Nihonbashi Publishing, 2021, which introduces the care method using "Stretch Oral (registered trademark)". Followed the Stretching Method. In the ``tongue approach,'' the tongue is stimulated and stretched using ``Stretch Oral (registered trademark).'' Although this book discloses oral cavity conditioning that approaches the tongue, it does not disclose a vocal conditioning method.

The oral cavity conditioning method for each subject in Group B was "approach to the floor of the mouth and the base of the tongue." The method of "approaching the floor of the mouth and the base of the tongue" was the same as the method shown in FIGS. 1 to 8. That is, the conditioning method for group B includes a first step of approaching the floor of the mouth and a second step of approaching the base of the tongue. The first step includes repeatedly pressing down on the floor of the oral cavity in the oral cavity to repeatedly press and release the muscles included in the suprahyoid muscle group. The second step includes a 2-1 step in which the base of the tongue is raised relative to the floor of the oral cavity by an insert inserted between the back side of the tongue and the floor of the oral cavity, and a step 2-1 in which the back side of the tongue and the floor of the oral cavity are raised. and a step 2-2 of moving the tongue forward so that the base of the tongue presses the insert forward with the insert inserted therebetween.

Before administering oral conditioning, each subject was made to pronounce the vowel "ye-a-ou (i, e, a, o, u)" three times at BMP60, and the sound of each was recorded. The pitch of the vocalizations was free, and each vowel was pronounced continuously without separation.

Thereafter, each subject underwent the oral conditioning described above.

After completing the oral conditioning, each subject was asked to pronounce the words and recorded. The pronunciation was the same as the pronunciation method before oral conditioning. Pronunciation was performed within 10 minutes after the completion of oral conditioning.

Then, we performed acoustic analysis of the recorded voices. Acoustic analysis was performed by formant analysis. As formant analysis, the amplitude [dB] at each formant frequency was determined, and the values of the amplitude [dB] of each formant before and after conditioning were compared. Note that the formants are called a first formant F1, a second formant F2, a third formant F3, and a fourth formant F4 in descending order of frequency.

Figure 10 shows the results before and after conditioning for each vowel “i,e,a,o,u” pronounced by each subject in group A (A1, A2, A3, A4, A5, A6, A7, A8). It shows the difference [dB] between the numerical values of the amplitude [dB] of each formant. For example, when subject A1 pronounces the vowel "i", the differences in formants F1, F2, F3, and F4 before and after conditioning are "3.78," "-2.39," and "0," respectively. .70” and “-7.06”. "3.78" indicates that the value [dB] after conditioning is 3.78 [dB] larger than the value [dB] before conditioning. "-2.39" indicates that the value [dB] after conditioning is smaller than the value [dB] before conditioning by 2.39 [dB]. "0.70" indicates that the value [dB] after conditioning is larger than the value [dB] before conditioning by 0.70 [dB]. "-7.06" indicates that the value [dB] after conditioning is 7.06 [dB] smaller than the value [dB] before conditioning.

In the table of FIG. 10, the columns where the value [dB] after conditioning is smaller than the value [dB] before conditioning are shown in white. Columns in which the value [dB] after conditioning is larger than the value [dB] before conditioning are shown in gray. In addition, numerical values in columns in which the value [dB] after conditioning is greater than the value [dB] before conditioning by 5.0 [dB] or more are in bold. Note that an increase of 6 [dB] doubles the loudness of the sound, so if it is greater than 5.0 [dB], it can be said that the loudness of the sound is approximately twice as loud.

Figure 11 shows the results before and after conditioning for each vowel "i,e,a,o,u" pronounced by each subject in group B (B1, B2, B3, B4, B5, B6, B7, B8). It shows the difference [dB] between the numerical values of the amplitude [dB] of each formant. The table in FIG. 11 is created in the same way as the table in FIG.

Referring to FIG. 10, in Group A, there are several "gray" columns that indicate that the sound has become louder after conditioning, but there are also "white" columns that indicate that the sound has become quieter after conditioning. There are about the same number of columns as "gray" columns. In FIG. 10, there are not many formants whose sound became louder than 5.0 [dB] after conditioning.

Also, in FIG. 10, when looking at the average value [dB] of the numerical difference before and after conditioning for each formant, the average value is small overall and distributed in a small value range centered on 0. There were no cases where the sound became louder than 5.0 [dB] after conditioning, and there were many cases where the sound became quieter after conditioning.

Therefore, in group A, even if the sound becomes louder after conditioning, there are also cases where the sound becomes quieter after conditioning, so the increase or decrease in sound before and after conditioning is simply a change in pronunciation before and after conditioning. It is understood that this was caused by variations. Therefore, in group A, there is little or no improvement in vocalization due to conditioning. Therefore, the oral cavity conditioning performed on group A has little or no effect as vocal conditioning.

On the other hand, referring to FIG. 11, in group B, the number in the "gray" column indicating that the sound became louder after conditioning was increased, and the number in the "white" column indicating that the sound became quieter after conditioning. sufficiently greater than the number of Furthermore, the number of formants whose sound became louder than 5.0 [dB] after conditioning is also larger than in FIG. 10.

In addition, in Figure 11, when looking at the average value [dB] of the numerical difference before and after conditioning for each formant, the average value is large overall, and the sound becomes louder by more than 5.0 [dB] after conditioning. However, none of them have become quieter after conditioning. Therefore, in group B, improvement in vocalization due to conditioning was observed. Therefore, it can be seen that the oral cavity conditioning performed on group B is effective as vocal conditioning.

In group B, the increase in voice volume due to conditioning was relatively large for the vowels "i, o, u (i, o, u)", and especially large for the vowels "o, u (o, u)". On the other hand, the vowel "e" has a slightly smaller increase in voice volume, and the vowel "a" has the least increase. The reason that the improvement in pronunciation after conditioning differs for each vowel is considered to be related to the conditioning method applied to group B.

That is, as shown in FIG. 12, the vowel "o, u" is pronounced by raising the "back side" of the tongue. The vowel "i" is pronounced by raising the "front" of the tongue. The vowel "e" raises the "front" of the tongue, but it may be lower than the vowel "i", and the vowel "a" does not require as much lifting of the tongue. do not.

For group B, loosening the floor of the mouth and the base of the tongue makes it easier for the tongue to lift, and the airway is widened. It is thought that the loudness of the voice for "o, u (i, o, u)" has greatly improved. In addition, because the back of the tongue (the base of the tongue) is relaxed, the loudness of the voice especially during the vowel "o, u", which requires the back of the tongue to be raised high, has improved significantly. considered to be a thing. In this way, by loosening the floor of the mouth and the base of the tongue, the pronunciation of the vowels "i, o, u (i, o, u)" is greatly improved, and the pronunciation of the vowels "o, u (o, u)" is greatly improved. The improvement effect is particularly large.
