Voiceless and Voiced Consonants:
One way that we categorize consonants is by determining whether they are "voiceless" or "voiced." It's important to know the difference between these types because the length of a vowel that precedes a consonant is determined by whether the consonant that follows it is voiceless or voiced. Also, knowing whether a sound is voiceless or voiced will help to correctly pronounce letters such as -ed and -s at the ends of words.

First, let's learn how to distinguish between a voiced and a voiceless consonant. Place your fingers in the front, middle part of your neck. Now say /z/ as in the word "zoo." Now, let's make it longer: zzzzzzzzzzz. You should feel a vibration in your vocal cords. This is how you know that the /z/ sound is voiced. Now let's try this with the /s/ sound as int he word "sat." Say /s/. Now let's prolong it: sssssssssss. This time there was no vibration in your vocal cords, so this consonant is considered unvoiced. That's all there is to it. The tongue and lip positions of the /z/ and /s/ are identical. The only difference between them is vibration or no vibration. Look at the other consonant pairs that are produced exactly the same way, except for the vibration in the vocal cords.

Voiceless Consonants
(vocal cords do not vibrate)
Voiced Consoants
(vocal cords vibrate)
How to Produce the Sound

/p/ pet, rope
/b/ bet, robe
Lips start fully together, then part quickly to produce a small release of air.

/t/ ten, seat
/d/ den, seed
Tip of the tongue is slightly tense as it firmly touches and then releases the gum ridge.

/k/ class, back
/g/ glass, bag
Back of tongue presses up against soft palate (back of mouth) and releases.

/f/ fault, leaf
/v/ vault, leave
Lower lips lightly touch upper teeth; vibration occurs on the lips from the flow of air created.

/th/ thank, breath
/th/ this, breathe
Tip of the tongue touches back of front teeth or edges of front teeth. Air flows out between tongue and teeth.

/s/ sink, price
/z/ zinc, prize
Sides of tongue touch middle and back upper teeth. Tip of tongue is lowered a bit. Air flow out of middle part of the tongue.

/sh/ pressure, wish
/zh/ pleasure, massage
Tip of tongue is down, sides of tongue are against upper teeth on sides of mouth. Air flows out through middle of tongue.

/ch/ choke, rich
/j/ joke, ridge
Tip of tongue is down, sides of tongue are against upper teeth on the side of mouth. Tip of tongue quickly touches gum ridge and then releases.


More Voiced Consonants
Now let's go through the rest of the consonant sounds of English. These consonants are all voiced, but they have no cliceless pair. Make sure that you feel the vibration in your vocal cords as you say them.

/m/ mom, from, lemon
Lips together. Air flows out of the nose.

/n/ non, fun, any
Tip of tongue touches gume ridge, and the sides of the tongue touch upper teeth; air any flows out of the nose.

/ng/ going, spring, king
Back of the tongue touches the soft palate; air flows out of the nose.

/l/ love, will, yellow
Tip of tongue touches upper gum ridge. Tongue is tense. Air comes out on the sides of the tongue, at the corners of the mouth.

/r/ red, four, card
There are two ways to produce this sound:
1: Tip of tongue curls a bit and then is pulled back slightly.
2: Tip of tongue is down; center of the tongue touches hard palate.

/w/ win, lower, quiet
Rounded lips as for the vowel /oo-/ in moon. Air flows out through the lips. Tongue is in position for the vowel sound that follows the /w/.

/y/ yes, mayor, young
Tip of tongue touches lower front teeth. Front of tongue is raised near the hard palate.


The Consonant /h/
This final consonant sound is voiceless and does not have a "voiced pair" that it corresponds to.

/h/ happy, behave, who
Vocal cords are tense and restricted, back of tongue is pushed against the throat to create friction as the air flows out from the back of the mouth.
