Fatigue Voice Improvement Method Part II

To Reference FV Part I. Click here.

To dramatically improve voice, one must be familiar and knowledgeable with their own throat and personal attributes.
I name FV stands for Fatigue Voice which is when the extrinsic muscles are  tired and or strained due to overuse of the voice.
If FV is not diagnosed or treated, it will eventually lead to vocal impairments or organic diseases, such as : vocal cord nodules, vocal fold polyps, hyperfunctional dysphonia or a condition know as hypertonic voice disorder.

(Improvement method of FV)
Please try after using voice:
1: Slowly stretch with deep breaths (Truly right efficient breaths)
2: Apply a warm towel to your throat for five minutes in the supine position
3:Get enough rest or sleep
If your condition is still not chronic or diseased, the above 3 are OK.
Please try it and create a better voice!


Fatigue Voice Summary Part I

As I said before, if your body is tired or stressed, your voice quality will also suffer. Physical and mental conditions affect the voice.
Let’s discuss how using your voice too much can result in negative changes to the throat (vocal chord and external laryngeal ).
The biggest most noticeable change, would be that the vocal chord becomes ‘hyperemic’ and each muscle of the larynx would move the vocal chords which in turn could cause a metabolism disorder. the definition of hymeremic is any increase in the quantity of blood flow to a body part. If two vocal folds vibrate, too wide, and too long, capillaries begin to dilate and ultimately increase the blood flow surrounding the vocal cord muscles.
As a result, vocal fold gets more weight, and the voice gets slightly low in pitch. (Your pitch aims to be correct, but your exact pitch is a  fewer hertz lower than the correct notes)
One more important point is that the mucosa does not have anything to do with the cause or effect of the hyperemic process, in this specific example because there is no blood vessel in mucosal tissue.
However, if you keep abusing the vocal folds, it will cause the tissue fluid (blood plasma) to collect in Reinke’s space, and cause the vocal folds to get heavy. So if you still keep using vocal folds, the nonkeratinized stratified squamous epithlium swells and creates a vocal fold polyp. A polyp, sometimes referred to as a nodule, is growth that develops on the vocal cords of people who constantly strain their voices. A vocal fold polyp is usually localized to a specific area of the vocal chord but if overuse continues, the vocal folds will more than likely also show signs of inflammation, swell and become flabby. If you get in this situation, you might have to seek surgery to correct this issue. The way to identify overuse your voice and voice straining would be to listen to if the natural voice sounds like a lower pitch than normal or for falsetto flats.
If you feel a change to your natural voice and or falsetto voice, this could mean that it has been overworked. I recommend seeking a doctor who specializes in the vocal sound field.
–Level of Fatigue Voice–
Level1:” the voice quality is normal ” ”not a lot of change in the falsetto”
Level2:” the voice quality is normal ” ”falsetto is low”
Level3: ”the voice quality gets worse (hoarse voice)” ”hard to control voice pitch”

The muscles of the larynx, use vocalization as a form of exercise. The larynx and vocal chords constantly move, and are similar to the movements of an instrument. The muscles for moving the vocal chords get a work out when constricting of the resonance chamber occurs. It has been proven that practicing routine vocal maneuvers can lead to the development of specific control over individual muscle groups within the vocal mechanism.
Any sport can make muscles fatigued, if you overwork them.
Keep in mind, the neighboring muscle of the larynx is considered to be (1)thin and small (2)compensating controls is complicated (3)ambiguity (4)perceiving tissue is difficult, and vulnerable to overuse.
Even if lactic acid accumulates in a muscle, you would not notice until you felt a change in your voice, because it’s hard to distinguish the sensation of fatigue. The muscle can contract by itself but cannot extend because of its property.
This means that muscle movement does not work properly without exogenous forces, just like a seesaw.
The antagonistic actions are unclear when it comes to the muscles of the larynx …  muscle contractions would in fact definitely be constant when overused. Which sometimes causes hypertonic phonation or LDP (Larynx Deep Position) and makes the quality of phonatory function worse.
Furthermore, it’s hard to control tone pitch. It reduces voice volume and produces hoarseness. For preventing this issue, consider the condition of your throat and use your voice properly.

We will discuss the improvement method in part II.

Note 1:  FV = FatigueVoice, it means that extrinsic muscles have fatigue due to an overused voice.

Note 2 : LDP = Larynx Deep Position is when the secretory fluid decreases in the intralaryngeal muscle due to bad blood flow in the superior laryngeal artery. This causes that the throat to dry out. (There are many different factors to be considered because each persons individual thickness between the thyrohyoid bones varies)

Breath = The driving power of voice

When comparing phonation(singing) to playing the acoustic guitar (stroking),the breath is similar to the hand motion of playing a guitar.(stroke)
If the stroke was weak while play a guitar, it woud not be able to control or create sounds and, or music .
It is the same with breathing, that’s why, breath is very important.
Please see the following figures.
It’s good to understand the mechanics of vocalization to create a singing voice as first step.
Human respiratory system
Note 1: You might not need to know structure or mechanics, if you do not have a  problem grasping phonation. But, if you feel like ”you are not good at hitting high registers”, ”hard to make a  long breath, or hold a long note” or maybe just ”want to sing better”. Research and understanding, and reading these pages about the  the throat will only make you better at achieving those vocal goals.

Note 2 : The body of an acoustic guitar in comparison to a human resonance chamber. Focus on the pharyngeal cavity. This plays a very important role,  because this will ultimately decide the tone and sound of your voice.

I have outlined the following steps to share with you in which you should focus on, about, ‘How to take a breath properly in my ‘Voice Care Salon’
(1 ) Extension of the internal and external intercostal muscles.
(2) Movements associated with the levator scapulae and the subclavian muscle.

Understanding the Movements of the Vocal Cord Mucosa

You can imagine a falsetto or mixed voice easily if you know and understand how to control/move the vocal cord mucosa.
Please see here about vocal fold.
Here are some key points :
The vocal cord mucosa can change its figure & flexibly, but never by itself. It can change only by exogenous forces and the internal capacity changes nothing.
I will explain how by demonstrating with Konjac foods and a hair dryer.
This experiment is using konjac foods as a comparative example of the vocal cord mucosa surrounding the vocal chord. Konjac is a food made from the root of a plant, which is widely known in English by its Japanese name, konnyaku (yam cake), being cooked and consumed primarily in Japan. The two basic types of yam cake are white and black. Pushing the cake through a grid of sharp blades at the end of a wooden box creates noodles, called shirataki, which are also sold in white and black colors.
For this experiment, I sliced the konjac thin, and placed each one parallel to eachother, mimicking the vocal cord mucosa. Being minful of gravity and needing to reenact air and wind as an example of the airflow used to create voice, I chose a hair dryer.
I then proceeded to use the hair dryer, to blow the surface of the konjac precisely, and then recorded this. Reviewing it in slow and paused motion.
I conducted the experiment several times, and came up with the following results.
This is rough sketch drawing displaying the movement of the vocal cord mucosa.
This picture shows the side of the horizontal surface, red is vocal muscle and pink is the vocal cord mucosa. The arrows distinctively show which direction the air flow was originating from.

1:The vocal fold closing.
2:The vocal fold is flipped up by the exalted breath, causing  the apical point to go up.
3:The bottom of mucosa moves forward.
4:The top moves backward and the bottom swells in the middle.
5:The top and bottom are supposed to return to the original position. The exalted breath affects the vocal fold return to the original position more at this time. This is i referred to as “Bernoulli’s Theorem.”

Bernoulli’s Theorem is when an increase in the speed of fluid occurs simultaneously with a decrease in pressure. Bernoulli’s principle can also be derived directly from Newton’s 2nd law. If a small volume of fluid is flowing horizontally from a region of high pressure to a region of low pressure, then there is more pressure behind than in front. This gives a net force on the volume, accelerating it along the streamline. In conclusion,  if fluid is flowing horizontally and along a section of a streamline, where the speed increases it can only be because the fluid on that section has moved from a region of higher pressure to a region of lower pressure; and if its speed decreases, it can only be because it has moved from a region of lower pressure to a region of higher pressure. Consequently, within a fluid flowing horizontally, the highest speed occurs where the pressure is lowest, and the lowest speed occurs where the pressure is highest.

This movement is can be varied considering the muscle size,thickness, and hardness.

If the vocal muscle is soft, it improves the vocal cord mucosa. Causing it to move more freely and making it easier to achieve complex movements, resulting in a rich tone. However, if you cannot control flexibly, it will be a difficult task to achieve and create rich pitches/tones.
If the vocal muscle is hard or rigid, expect these outcomes: Being unsuccessful in creating the pitch of a Passaggio, a Falsetto pitch will be thin/flat, and finally … not being able to combine the two, creating a mixed voice.

Take this knowledge and apply it, to understand and learn the movements of the vocal chords and the tissues that function and surround them.

Examining the Cross Section of the Vocal Cords

When described casually, most people say ”vocal cords.” The proper medical reference term is actually, ”vocal folds.”
Vocal folds are composed of mucosa tissue and muscle tissue.
Also known as, vocal cords mucosa and vocal cord muscles.
The vocal cord mucosa is covered by stratified squamous non-keratinizing epithelium.
Well, let me say a little-know information.
When examined through a microscope, you can see the cross section of vocal chords, the vocal ligaments between the vocal cords mucosa and muscle.
The vocal ligament connects the processus vocalis cartilaginis arytenoidei to the anterior commissure of thyroid cartilage and bear vocal folds.
If the stretching/elasticity rate of the vocal ligaments are different between the right and left, it is sometimes awkward or uncomfortable to move the vocal cords from right to left. This is not common, and most people are oblivious to it.
There is a space between the vocal ligament and the vocal cords mucosa (nonkeratinized stratified squamous epithlium). It is not completely hollow, it’s filled with loose connective tissue. This is referred to as, ”Reinke’s space.”
In rare instances, a vocal cord edema may form. That is when an overflow or pooling of blood and fluid is collected in ”Reinke’s space.” This is caused by, an imbalance of the blood and fluid, resulting in a hoarse voice or rough/scratchy low voice.
If the fluid is lacking in Reinke’s space, the vocal cords mucosa shrinks, and the nonkeratinized stratified squamous epithlium is wrinkled. Which in turn, results in the glottis opening, creating hoarseness and or harsh high notes.
Let summarize below.
The vocal folds are composed of
‘’Nonkeratinized stratified squamous epithlium’’=>’’Reink’s space’’=> ‘’Vocal ligament’’=>’’Vocal cords muscle’’.
The above is a rough sketch, only because it does not go into depth, showing the conus elasticus. But it is very useful in this instance of observing the layering pattern, and location of the facts stated above.

Note1: A ligament exists in a false vocal cord (vestibule), and this is very important to observe for improving phonation.

Note2: It is known that loose connective tissue easily expands due to infection or irritation. That’s why swelling and a hoarse voice occur when you catch a cold or strain/over exhaust the use of your voice.
