Glottalization of vowels and other sonorants is most often realized as creaky voice (partial closure). Glottalization of obstruent consonants usually involves complete closure of the glottis; another way to describe this phenomenon is to say that a glottal stop is made simultaneously with another consonant. In certain cases, the glottal stop can even wholly replace the voiceless consonant. The term 'glottalized' is also used for ejective and implosive consonants; see glottalic consonant for examples.

Vocal cord dysfunction Vocal cord dysfunction Vocal cord dysfunction (VCD), also known as Paradoxical Vocal Fold Motion (PVFM) or Paradoxical Vocal Cord Movement (PVCM), is a pathology affecting the vocal folds (commonly referred to as the vocal cords). VCD is characterized by full or partial vocal fold closure, causing difficulty and distress during respiration, especially during inhalation. Symptoms of VCD are not always present. Rather, they often occur episodically, often defined as "attacks," where the sufferer will be symptomatic for a short period of time. Due to the similarity in symptoms, VCD attack are often mistaken for asthma attacks or laryngospasms. Although several
