The term "glottal" refers to sounds produced in the glottis, which is the space between the vocal cords in the larynx. Glottal sounds are important in various languages and can include glottal stops, where airflow is momentarily halted, as seen in the pronunciation of the word "uh-oh." In phonetics, glottalization can affect the quality of consonants and vowels. For example, in some dialects of English, the glottal stop may replace the "t" sound in words like "butter." Understanding glottal sounds is essential for studying linguistics and the mechanics of speech.
