According to Chinese medicine, the human body’s speaking voice is emitted from the larynx, which is powered by qi. The kidneys are responsible for the absorption of qi and the lungs are responsible for the emission of qi. The qi of the lungs and kidneys is emitted from the larynx, which in turn produces the voice.
If the kidneys are deficient, the qi of the kidneys cannot help the lungs to absorb the clear qi, and the qi cannot be taken in by the kidneys, so it is difficult to keep the breath deep enough, and the symptoms such as more breathing, less breathing, and shallow breathing will be manifested.
If the breath is not able to continue, the sound will not come out smoothly, which will lead to a decrease in volume. If kidney yin deficiency fails to nourish the fluid, fluid deficiency and inflammation of the fire, resulting in unfavorable throat, hoarseness will also occur.
Thus, Kidney deficiency may lead to a change in speaking voice. If there is a change in voice, you should consult a professional doctor for a clear diagnosis, so as to avoid delaying your condition by self-judgment.
