Those with hoarse throats have persistent hoarseness, and any manner of vocalization is manifested as hoarseness. Smoky voice singers speak normally, but sing with a hoarse tone.
Smoky voice is to use part of the vocal folds to vibrate during vocalization, and then amplify this part of the vibration through the resonating cavity, making the otherwise normal middle and high vocal regions of the voice have a metallic cold texture, which is a very high vocal skill.
The hoarseness of the throat can be related to the abnormal vibration frequency of the vocal folds, vocal dysfunction, etc., often due to acute laryngitis, chronic laryngitis, vocal polyps, vocal nodules, vocal white spots and other diseases, resulting in a hoarse vocal quality.
When you need to determine whether you have a hoarse throat or a smoky voice, you can actively consult a doctor for a systematic examination to clarify the diagnosis and cause of the disease.
