Document Summary
When you have laryngitis your vocal fold tissues become swollen (edema), causing change in voice quality. The affected individual sounds horse and, if severe enough, may experience a complete loss of voice (aphonia). Speech language pathologists use three descriptors: harsh: voice is associated with excessive muscle tension. The vocal folds are pressed together tightly with a quick release during each cycle of vibration: breathy: voice is produced with partial whisper. The vocal folds are brought together so that they can vibrate, but a space between them remains. The larger the space between the folds, the greater breathier phonation. If the space is wide enough, the only sound produces is a fricative noise whisper: hoarse: a voice that is both harsh and breathy. It results from irregular vocal fold vibration, typically from differences in the mass and shape of the two folds. Laryngitis is one of a number of problems that can affect vocal fold function.
