"Diphthong" Natural Recordings by Native Speakers
A diphthong is a single vowel sound made by gliding from one vowel quality to another, usually represented by a combination of two vowel letters or symbols, such as "ai" in "buy" or "oy" in "boy". In phonetics, a diphthong is a type of glide, where the tongue's position changes smoothly over time, resulting in a continuous vowel sound. Diphthongs are often distinguished from triphthongs, which involve three vowel sounds in a similar gliding pattern.

Diphtheria is a serious and potentially life-threatening bacterial infection that can occur when a person's throat and tonsils become infected with the bacterium Corynebacterium diphtheriae. The infection causes the formation of a membrane in the throat that can close off the airways, leading to suffocation, and also can cause weakness or paralysis of the face, arms, or legs. Diphtheria is typically spread through direct contact with an infected person's saliva or mucus, and its symptoms can include sore throat, fever, and difficulty swallowing.

Diphtheritis is a severe form of diphtheria, a serious bacterial infection caused by Corynebacterium diphtheriae. Diphtheritis is characterized by the presence of a thick, greyish membrane on the tonsils, throat, or nose, which can block the airways and lead to life-threatening complications such as respiratory failure, heart problems, and neurological damage.
Diphthongation refers to the process of turning a vowel sound into a combination of two vowel sounds, often pronounced smoothly and continuously, like in the words "oy" or "ou." In some languages, such as English, diphthongation occurs when a vowel is followed by a glide or a semivowel, resulting in a modified pronunciation.
To diphthongise means to pronounce a vowel sound as a combination of two vowel sounds, with the sound changing smoothly from one to the other. For example, the "ou" in English words like "noise" or "boat" is a diphthong.
Diphthongising is the act of pronouncing a vowel sound as if it were a combination of two distinct vowel sounds, typically a glide from one vowel to another, often used in linguistics and phonetics to describe the process of changing a single vowel sound into a diphthong.
