Voiced vs. Voiceless Consonants
Voiced vs. Voiceless Consonants Phoneticists (who study the sound of the human voice) divide consonants into two types: voiced and voiceless. Voiced consonants require the use of the vocal cords to produce their signature sounds; voiceless consonants do not. Both types use the breath, lips, teeth, and upper palate to further modify speech. This guide presents the differences between voiced and voiceless consonants and gives you some tips for using them. ThoughtCo / Jaime Knoth Voiced Consonants Your vocal cords, which are actually mucous membranes, stretch across the larynx at the back of the throat. By tightening and relaxing as you speak, the vocal cords modulate the flow of breath expelled from the lungs. An easy way to determine whether a consonant is voiced or not is to place a finger on your throat. As you pronounce a letter, feel the vibration of your vocal cords. If you feel a vibration the consonant is a voiced one. These are the voiced consonants: B, D, G, J, L, M, N, Ng, R, Sz, ThÃ (as in the word then), V, W, Y, and Z. But if consonants are only single letters, what are Ng, Sz, and Th? Theyre common sounds that are produced by blending the two consonants phonetically. Here are some examples of words that include voiced consonants: traveledglovesshellsstartedchangedwheelsliveddreamsexchangedglobesphoneslistenedorganized Voiceless Consonants Voiceless consonants do not use the vocal cords to produce their hard, percussive sounds. Instead, theyre slack, allowing air to flow freely from the lungs to the mouth, where the tongue, teeth, and lips engage to modulate the sound. These are the voiceless consonants: Ch, F, K, P, S, Sh, T, and ThÃ (as in thing). Common words using them include: washedcoatswatchedbooksseatsdroppedcarts Vowels Vowel sounds (A, E, I, O, U) and diphthongsÃ (combinations of two vowel sounds) are all voiced. That also includes the letter Y when pronounced like a long E. Examples: city, pity, gritty. Changing Voice When consonants are put in groups, they can change the vocal quality of the consonant that follows. A great example is the past simple form of regular verbs. You can recognize these verbs because they end in ed. However, the consonant sound of this ending can change from voiced to voiceless, depending on the consonant or vowel that precedes it. In almost all cases, the E is silent. Here are the rules: If the ed is preceded by a voiceless consonant such as K, it should be pronounced as a voiceless T. Examples: parked, barked, markedIf the ed is preceded by a voiced consonant sound such as B or V, it should be pronounced as a voiced D. Examples: robbed, thrived, shovedIf the ed is preceded by a vowel sound, it should be pronounced as a voiced DÃ because vowels are always voiced. Examples: freed, fried, liedException: If the ed is preceded by T, it should be pronounced a voiced id sound. In this case, the e is pronounced. Examples: dotted, rotted, plotted This pattern can also be found with plural forms. If the consonant preceding the S is voiced, the S will be pronounced phonetically as a Z. Examples: chairs, machines, bags If the consonant preceding the S is voiceless, then the S also will be pronounced as a voiceless consonant. Examples: bats, parks, pipes. Connected Speech When speaking in sentences, the ending consonant sounds can change based on the following words. This is often referred to as connected speech. Here is an example of a change from a voiced B in the word club to a voiceless P because of the voiced T in to of the following word: We went to the club to meet some friends. Here is an example of a change from a voiced D past simple verb changed to voiceless T: We played tennis yesterday afternoon.
