Between the user's face and the mirror facing the user's face so that the user can see the entire mouth and vocalization instrument together through the mirror.

  At this time, the user adjusts one or more of the position of the voice training device, the mirror, or the user's own face while looking at his / her mouth and the horizontal guideline member reflected in the mirror. In the state of the mouth when uttering the vowel “I”, the mouth corners of both sides of the mouth that can be seen through the mirror overlap each other on the horizontal guideline member that forms a straight horizontal reference line in the horizontal direction. Adjust to.

  After this adjustment, the user looks in the mirror and speaks differently, even if the mouth opens in the horizontal direction, the mouth angle on both sides of the mouth is a straight horizontal reference that is created by the horizontal guideline member. By practicing vocalization by moving the muscles around the mouth so that it moves along the line, the muscles around the mouth move consistently even when unconscious, correcting distortion of mouth movements during vocalization it can.

  In addition, the horizontal horizontal reference line created by the horizontal guideline member makes it easier to see the movement of the face when speaking, reducing the movement of the skull (maxilla) side of the face unnaturally when speaking. Or, it can be conscious to suppress, and the stress and fatigue of the muscles around the neck accompanying the up and down movement of the upper jaw can be reduced, and furthermore, the throat can be prevented from being lowered and the sound volume can be reduced.

  Moreover, since the skull's back and forth movement and vertical movement are reduced or suppressed by uttering without moving the upper jaw, it becomes easier to utter while the throat is open, and the voice generated in the vocal cords of the soft palate in the mouth It becomes easy to resonate in a certain place, and it becomes possible to utter with a rich sound.

  In addition, the back and forth movement and vertical movement of the skull during utterance are reduced or suppressed, so the position and orientation of the mouth during utterance is made constant, and the direction of the voice (sound wave) from the mouth toward the microphone and the listener is made constant. And a stable voice volume can be transmitted to the listener.

  The vocal training device of the second invention is the vocal training device of the first invention, and is held by the horizontal guideline member, and in the held state, it is perpendicular to the horizontal guideline member in the vertical direction in a straight line when viewed from the front.

  The pair of support portions 2a, 2a have a vertically long shape, and both have a predetermined lateral width. The connecting portion 2b is integrally connected to the base end portions of the pair of support portions 2a and 2a. The connecting portion 2b has a function of connecting the pair of support portions 2a and 2a to keep a distance between the pair of support portions 2a and 2a in a lateral direction, and is formed in an arc shape having a constant width curved in an arc shape when viewed from the front. Has been. Further, the arc-shaped portion of the connecting portion 2b is formed so that its curvature is substantially constant in order to make it difficult to break due to local stress concentration. Moreover, the upper end part of the attachment part 2c is integrally connected by the lower end part of the circular-arc-shaped part of the connection part 2b.

  The main plate 2d of the mounting portion 2c is formed integrally with the pair of support portions 2a and 2a and the connecting portion 2b using a single plate material. A slit 2d1 having a predetermined length is cut from the lower end of the main plate 2d of the mounting portion 2c on the center line in the vertical direction. The attachment portion 2c has a structure in which a main plate 2d and a sub plate 2e having the same thickness are joined by a cross-phase notch contact. A slit 2e1 having a predetermined length that engages with the slit 2d1 of the main plate 2d is vertically formed from the upper end. The main plate 2d and the sub-plate 2e are cut in the direction so that the slits 2d1 and 2e1 are engaged with each other so as to intersect each other in a plan view (bottom view).

  The attachment part 2 c is held by the user's hand of the utterance practice instrument 1 or attached to and held by a microphone holder 61 attached to the upper end of the microphone stand 60. The attachment portion 2 c has a wide portion 2 c 1 having a width larger than the diameter of the inner peripheral portion of the microphone holder 61. The wide portion 2c1 of the attachment portion 2c is held in an interference fit state on the inner peripheral portion of the microphone holder 61 (see FIGS. 6 to 8).

  The pair of support portions 2a and 2a are provided in parallel to each other with a predetermined interval in the lateral direction. In order to detachably attach the hooking members 5 and 5 in the horizontal guideline member 3 to the pair of support portions 2a and 2a, the upper and lower two circular hooking holes 2f are spaced apart in the vertical direction. 2f is respectively drilled, and the longitudinal direction end portion of the horizontal guideline member 3 is inserted into each hooking hole 2f.

  Further, the frame member 2 has a configuration in which the distal ends of the pair of support portions 2a and 2a are opened upward, and is in the front-rear direction (see FIG. 1) surrounded by the pair of support portions 2a and 2a and the connection portion 2b. An opening 2g penetrating in the direction perpendicular to the paper surface is formed. The opening 2g of the frame member 2 is a part for arranging the pair of horizontal guideline members 3 and 3 and the pair of vertical guideline members 4 and 4, and the user places the utterance practice device 1 in front of the face. In order to observe the movement of his / her mouth through the mirror, a penetration is formed (see FIGS. 7 and 8).

  The pair of lateral guideline members 3 and 3 are provided between the pair of support portions 2a and 2a in a linear state in the lateral direction, and are provided in parallel with a predetermined interval therebetween in the longitudinal direction. Yes. In addition, the pair of horizontal guideline members 3 and 3 and the connecting portion 2b are separated in a state of being spaced apart at a predetermined interval in the vertical direction, and by this separation, the lower jaw of the user is mirrored from the opening 2g of the frame member 2. It can be visually recognized through (see FIGS. 7 and 8). Each lateral guideline member 3 is stretched between the pair of support portions 2a and 2a in an extended state accompanied by an elastic restoring force.

  The horizontal guideline member 3 is a linear wire, and is formed of a stretchable wire that can be elastically stretched in the linear direction. Further, the lateral guideline member 3 is formed such that its outer diameter can be elastically expanded and reduced. The horizontal guideline member 3 is, for example, an elastic wire that can be elastically expanded and contracted is a rubber string having a circular cross section.

  As described above, the elastically stretchable stretchable wire used for the horizontal guideline member 3 is a rubber cord. Therefore, the elastic wire is stretched between the pair of support portions 2a and 2a in an elongation state less than the maximum elongation of the rubber cord. It is preferable to do. This is because the rubber material woven into the rubber string is easily cut due to deterioration over time by stretching in a stretched state less than the maximum elongation.

  Further, since the horizontal guideline member 3 is stretched between the pair of support portions 2a and 2a in a state where the predetermined amount is extended, the linear guideline 3 is not slackened by the elastic restoring force accompanying the extension. It becomes easy to make a horizontal straight line that becomes a horizontal reference line when the mouth corner is moved by the horizontal guideline member 3 (see FIGS. 7 and 8).

  Further, the horizontal guideline member 3 is provided with hooking members 5 and 5 detachably attached to the pair of support portions 2a and 2a at both ends in the horizontal direction (longitudinal direction). Each hooking member 5 in the horizontal guideline member 3 is formed in a spherical shape, and its outer diameter is larger than the inner diameter of each hooking hole 2f. For this reason, each hooking member 5 can be hooked on the peripheral edge of each hooking hole 2f.

  Each of the vertical guideline members 4 is movable in the horizontal direction along the pair of horizontal guideline members 3 and 3 and is held by the pair of horizontal guideline members 3 and 3. , 3 extends in a straight line when viewed from the front in a vertical posture.

The through-holes 4a are penetrated in a state where the outer diameter of the lateral guideline member 3 is elastically contracted. Due to the elastic restoring force accompanying the elastic contraction of the outer diameter of the horizontal guideline member 3, the horizontal guideline member 3 is brought into pressure contact with the inner peripheral surface of each through-hole 4a. 4 and 4 are fixed to the pair of horizontal guideline members 3 and 3.

  Next, with reference to FIG.6 and FIG.7, the speech practice method using the speech practice instrument 1 of a present Example is demonstrated.

  6 is a side view showing the usage state of the vocalization training device 1, and FIG. 7 is a front view of the vocalization training device 1 and the user's face 50 reflected through the mirror 70 in the usage state of FIG. In particular, FIG. 7 is a diagram illustrating a state in which the user has uttered the vowel “I”, and FIG. 8 is a diagram illustrating a state in which the user has uttered the vowel “U”.

  First, as shown in FIGS. 6 and 7, the utterance practice device 1 of the present embodiment has a pair of support portions 2a, 2a on the upper side and a mounting portion 2c on the lower side, a pair of support portions 2a, 2a, the connection part 2b, and the attachment part 2c are attached to the microphone holder 61 attached to the upper end of the microphone stand 60 in such a posture that the front part Y is Y-shaped. Note that the microphone holder 61 has a posture in which the inner peripheral portion penetrates in the vertical direction.

  Specifically, when the wide portion 2c1 of the attachment portion 2c is inserted into the inner peripheral portion of the microphone holder 61 of the microphone stand 60, the attachment portion 2c is held in an interference fit state in the microphone holder 61, and the voice training device 1 is firmly fixed to the microphone holder 61. The height of the microphone stand 60 is adjusted so that the utterance practice device 1 is disposed between the user's face 50 and the mirror 70.

  As shown in FIG. 6, the utterance practice device 1 attached to the microphone holder 61 is placed in front of the user's face 50, and a mirror 70 is provided so as to face the user's face 50 farther than the utterance practice device 1. So that the user can see the entire mouth and the utterance practice device 1 through the mirror 70 together. The utterance practice device 1 may be held by the user's hand without being attached to the microphone holder 61 of the microphone stand 60.

  At this time, the user stretches his back, pulls the lower jaw 52 and takes a relaxed posture with no extra force on the neck, and the user puts his entire mouth and the vocalization training device 1 together through the mirror 70. The user adjusts one or more of the positions of the user's face 50, utterance practice instrument 1, or mirror 70.

  The position adjustment of one or more of the user's face 50, the utterance practice instrument 1, or the mirror 70 will be described more specifically. First, as shown in FIG. ”So that the horizontal guideline member 3 on the upper side, which is linear in the lateral direction, overlaps the lower end of the nose 54 that is visible through the mirror 70 or the periphery thereof. In addition, the horizontal guideline member 3 on the lower side where the mouth corners 53 and 53 on both sides of the mouth that can be seen through the mirror 70 are linearly formed in the lateral direction is adjusted so as to overlap.

  Furthermore, in addition to adjusting the position of the pair of lateral guideline members 3 and 3 in this way, adjusting the position of one or more of the user's face 50, utterance practice instrument 1, or mirror 70. Thus, while maintaining the shape of the mouth when the user himself utters the vowel “I”, the mouth corners 53 and 53 on both sides of the mouth that can be seen through the mirror 70 are linear in the vertical direction. The pair of vertical guideline members 4 and 4 are also adjusted so as to overlap each other.

  Here, when the distance in the horizontal direction between the pair of vertical guideline members 4, 4 that can be seen through the mirror 70 is wider than the width of the mouth corners 53, 53 on both sides of the user's own mouth, the pair of vertical guideline members 4, 4. 4 may be moved in the horizontal direction along the pair of horizontal guideline members 3 and 3 to reduce the distance between the pair of vertical guideline members 4 and 4.

  On the other hand, when the horizontal distance between the pair of vertical guideline members 4, 4 that can be seen through the mirror 70 is narrower than the width of the mouth corners 53, 53 on both sides of the user's own mouth, the pair of vertical guideline members 4. , 4 may be moved laterally along the pair of horizontal guideline members 3, 3 to widen the distance between the pair of vertical guideline members 4, 4.

  In this way, by moving the pair of vertical guideline members 4, 4 in the horizontal direction and adjusting the distance in the horizontal direction, the corner angles 53, 53 on both sides of the mouth are formed on the pair of vertical guideline members 4, 4 viewed through the mirror 70. In the case of matching, it is possible to eliminate the troublesome fine adjustment such as slightly moving the position of the user, the utterance practice instrument 1 or the mirror 70 back and forth.

  Next, after adjusting the positions of the user and the vocalization training instrument 1 as described above, the user speaks so as to move the lower jaw 52 without moving the upper jaw 51 while looking at the mirror 70. For example, during voicing practice, vowels are uttered in the order of “U” (see FIG. 8), vowel “o”, vowel “a” (see FIG. 7), vowel “e”, and vowel “a”. .

  At this time, as shown in FIG. 7 and FIG. 8, even if the spoken words are different and the opening (shape) of the mouth is large or small in the horizontal direction, the horizontal guideline with the mouth corners 53, 53 on the lower side of the mouth on the lower side. The mouth corners on both sides of the mouth can be moved along the horizontal horizontal reference line created by the member 3 and the mouth can be opened and closed in different directions (shape). Voices are generated by moving the muscles around the mouth so that 53 and 53 move in the vertical direction along the vertical vertical reference line that is formed by the pair of vertical guideline members 4 and 4 in the vertical direction.

  In addition, the user speaks to move the lower jaw 52 while keeping the upper jaw 51 from moving by preventing the lower end of the nose 54 or its peripheral portion from being displaced from the upper side guideline member 3. To do.

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. It can be guessed.

  For example, in the present embodiment, the attachment portion 2c has a structure in which the main plate 2d and the sub plate 2e are joined together by a cruciform notch contact, but the structure of the attachment portion 2c is not necessarily limited to this. For example, it may be a columnar body or a cylindrical body, as long as it can be gripped by or can be inserted into the microphone holder 61.

  In this embodiment, the pair of vertical guideline members 4 and 4 are provided. However, the number of the vertical guideline members 4 is not necessarily limited to this, and may be one, for example. In such a case, it is preferable to move one vertical guideline member 4 up and down so as to coincide with the center of the mouth.

  Further, in this embodiment, the pair of horizontal guideline members 3 and 3 are provided in parallel in the vertical direction (up and down direction), but the number of the horizontal guideline members 3 is not necessarily two. It may be provided with only one horizontal guideline member 3 for matching with the mouth corners 53 on both sides.

  Further, in this embodiment, when the user adjusts the position of the vocal training device 1, the user uses his / her mouth as the mouth when the vowel “I” is spoken. It is not limited to the vowel “I”, and may be a mouth shape at the time of utterance of vowels “D”, “A”, etc., as long as it has a mouth shape that widens the mouth corners 53, 53.

  In the present embodiment, the pair of vertical guideline members 4 and 4 can move in the horizontal direction with respect to the horizontal guideline member 3, but the pair of vertical guideline members 4 and 4 are spaced apart from each other by a predetermined distance. You may make it fix with respect to the horizontal guideline member 3 so that a movement is impossible.

  Further, in the present embodiment, the hooking members 5 provided at both ends in the longitudinal direction of the horizontal guideline member 3 may be hooked so as to be detachable from the hooking holes 2f in the support portions 2a. good. Then, when the horizontal guideline member 3 is cut or loosened, the horizontal guideline member 3 is exchanged by removing the hooking members on the horizontal guideline member 3 from the pair of support portions 2a and 2a, respectively. It can be stretched linearly between the support portions 2a, 2a.

  Moreover, although the utterance practice instrument 1 of the present embodiment has the horizontal guideline member 3 and the vertical guideline member 4 provided in the opening 2g of the frame member 2, the form of the utterance practice instrument 1 is not necessarily limited to this. For example, the frame member is formed of a transparent plate material having transparency in the front-rear direction, and a horizontal reference line extending in the horizontal direction corresponding to the horizontal guideline member is used instead of the horizontal guideline member. Instead, a vertical reference line extending in the vertical direction corresponding to the vertical guideline member may be provided by printing or engraving.

  Further, in this embodiment, the frame member 2 is formed in a Y shape when viewed from the front by connecting the connecting portion 2b and the mounting portion 2c to the pair of support portions 2a, 2a, but the shape of the frame member 2 is not necessarily limited thereto. It is not limited, For example, the front view "U" shape which eliminated the attaching part 2c may be sufficient. In addition, the form made from a pair of support parts and a connection part, a circular or elliptical ring shape in which the ends of the pair of support parts are connected to each other in an arc shape, a front view “concave” character shape in which the connection part is linear, Alternatively, the connecting portion may be linear in the lateral direction, and may have a “B” shape in front view in which the ends of a pair of linear supporting portions in the vertical direction are connected to both ends of a linear member parallel to the connecting portion.

  In this embodiment, the frame member 2, the pair of horizontal guideline members 3 and 3, and the pair of vertical guideline members 4 and 4 are formed separately, but they may be formed integrally. . In particular, the pair of lateral guideline members may be integrally formed using the same material as the frame member.
