👉 Semivocal, also known as a voiceless vowel, is a type of vocalization in which the consonant sound is not produced by the lips or tongue but rather by the soft palate. This type of vocalization can be found in many languages and has been observed in various species of animals. In English, for example, the word "cat" is semivocal because it contains a vowel (a) that cannot be produced by the lips or tongue, but rather by the soft palate
