Voiced and Voiceless
What is Voiced?
What is Voiceless?
Voiceless consonants do not use the voice. They are percussive and use hard sounds. Once again, you can test if a consonant is voiceless by putting your finger on your throat. You will feel no vibration in your throat, just a short explosion of air as you pronounce. Pronounce each of these consonant sounds and feel NO vibration in your throat.
Places and manners of articulation.
Vowels
Vowel is a sound in spoken language, such as an English ah! /ɑː/ or oh! /oʊ/, pronounced with an open vocal tract so that there is no build-up of air pressure at any point above the glottis. This contrasts with consonants, such as English sh! [ʃː], which have a constriction or closure at some point along the vocal tract. A vowel is also understood to be syllabic: an equivalent open but non-syllabic sound is called a semivowel.
Diphthongs
Diphthongs contrast with monophthongs, where the tongue or other speech organs do not move significantly and the syllable contains only a single vowel sound. For instance, in English, the word ah is spoken as a monophthong /ɑː/, while the word ow is spoken as a diphthong /aʊ/.
