Vowel sound意思

"Vowel sound" refers to the sound produced by the vocal cords when pronouncing a vowel, which is a letter or symbol that represents a speech sound made with the vocal tract open, allowing air to flow through without restrictions from the tongue, lips, or teeth. Vowels are distinct from consonants, which are sounds that typically involve a closure or narrowing of the vocal tract and are made by briefly stopping or restricting the flow of air.

In the English language, there are five main vowel letters in the alphabet: A, E, I, O, and U. Each of these vowel letters can represent multiple vowel sounds, depending on the context in which they are used. For example, the letter "A" can sound like "ah" as in "father," "ay" as in "day," or "awe" as in "spa."

Vowel sounds are an essential component of spoken language and play a crucial role in the formation of syllables and words. They are also a key factor in distinguishing between words that are spelled the same but have different meanings, known as homographs, as well as words that are pronounced the same but have different meanings, known as homonyms.
