Vocal Cord Strain and Overuse
Miley Cyrus has a naturally raspy voice partly because of vocal cord strain from years of intense touring and live performances. Repeated use of high-intensity singing can irritate the vocal folds, leading to a hoarse, textured tone.
Lifestyle and Vocal Habits
Factors such as smoking, dehydration, and irregular sleep can worsen vocal raspiness. Cyrus has openly discussed smoking, which dries and irritates the throat, while demanding schedules leave little time for vocal rest or consistent hydration.
Vocal Technique and Style Choices
Cyrus often sings with a pressed, gritty tone that emphasizes breathiness and distortion. This deliberate technique, combined with natural vocal texture, creates a signature raspy sound that fits her genre-blending pop and rock style.
Medical and Genetic Factors
Some raspy voices are linked to natural vocal fold thickness, allergies, or acid reflux, which can cause swelling or irritation. While Cyrus has not disclosed specific diagnoses, these common factors can permanently affect voice quality, as noted by voice specialists on sites like Mayo Clinic.
