The LDP of a hoarse voice and chorditis vocalis.

I will explain what are the differences between LDP of a hoarse voice and chorditis vocalis.
In the case of a hoarse voice, the glottis is opened by the pressured arytenoid cartilago corniculata, which causesLDP.
In the case of chorditis vocalis, the glottis is opened by a swollen vocal fold, because the vocal fold is inflamed.
These differences in how the glottis is opening are what produces different voice quality between the two conditions.
A brief description regarding the differences in sound and quality: A hoarse voice is when the glottis is forcibly opened, and a normal voice is mixed with leaking air. Conversely, the chorditis vocalis is when the vocal fold gets heavy and makes a low voice which is usually mixed with leaking air.

Note1:A hoarse voice can refer to a husky or even cracked voice. If the vocal fold does not close when exhaling, then it (the vocal fold) cannot vibrate properly, and the air cannot be converted to the voice effectively to make it sound normal and clear.
However, a moderate hoarse voice can become an attractive husky or cracked voice, if the amount of air leaked is minimal or at a low degree.

Note2:Hypertonic vocalization closely relates to LDP (Larynx Deep Position). Most of people have hypertonic vocalization with LDP, but LDP mentions the position of the larynx and commonly combined with displaying habitual straining of the throat muscles.
When we talk or sing with tension or nervousness, it is possible that only muscles are strained around the larynx, not a changed position of the larynx, which is why it is concluded to be to hypertonic vocalization.
