When it comes to vocal tract anatomy, the velum is probably less familiar to you than the lips, teeth, and tongue. Located at the back of your mouth, the velum allows you to produce both nasal sounds and velar consonants, like velar plosivesand fricatives. These are not the easiest sounds to produce—in the case of velar fronting, children sometimes substitute them with simpler sounds—but they are present and meaningful in most of the world's languages.
When you make sounds like k and g, you can feel the back of your tongue touching the velum.
The velum, also known as the soft palate, is part of the roof of the mouth located behind the hard palate.
Fig. 1 - The velum is located behind the hard palate at the back of the mouth.
The velum is responsible for velarconsonants in spoken languages. Velar consonants are a type of consonant sound produced by obstructing the airflow in the vocal tract with the back of the tongue against the soft part of the roof of the mouth, known as the velum. This is why they are called "velar," as the term comes from the Latin word 'velum' meaning 'veil' or 'covering'. Velar consonants are common in many languages, including English.
One sentence summary: A velar consonant is a sound that involves a constriction between the body of the tongue and the velum.
The velar consonants in English are [k], [g], and [ŋ] (the ng sound at the end of sing). These symbols represent the velar plosives and velar nasal in the International Phonetic Alphabet (IPA).
In English, some examples of velar consonants include:
Voiceless velar stop [k] as in the word "kick" /kɪk/.
Voiced velar stop [g] as in the word "go" /goʊ/.
Voiceless velar fricative [x] as in the Scottish pronunciation of "loch" /lɔx/.
Voiced velar nasal [ŋ] as in the word "sing" /sɪŋ/.
These examples show how the back of the tongue is used to create a blockage in the airflow at the velum, which is released to produce the specific velar consonant sounds.
Velar Plosives
A plosive is also called an oral stop.
A plosive, or oral stop, is a sound produced by completely cutting off and then abruptly releasing airflow through the vocal tract. Examples of plosives are the sounds [p, t, k, b, d, g].
The velar plosives are the voiceless [k] and voiced [g] sounds. These are also known as velar oral stops.

Articulatory Description
Examples in English
k
voiceless velar plosive
crack [kɹæk], cookie [ˈkʊkiː]
g
voiced velar plosive
goat [ɡoʊt], bag [bæɡ]
When you produce a velar plosive, you bring the body of your tongue to your velum and block your nasal cavity with your velum, completely cutting off the airflow from your lungs. Pressure builds up behind this constriction and creates a burst of air when released. If the velar plosive is voiced, the vocal folds are in vibration during the closure.
Fig. 2 - During a velar plosive, the body of the tongue touches the velum, cutting off airflow from the lungs.
Velar Fricatives
Velar fricatives are produced in the same placeas velar plosives but in a different manner.
A fricative is a sound produced by forcing air through a narrow constriction in the vocal tract. Examples of fricatives include the sounds [f, v, s, z, h].
Unlike velar plosives, velar fricatives are not phonemes in English. In other words, a velar fricative can't set one word apart from another in English. That said, the sound of a velar fricative can sneak into some English expressions. A groan of frustration (think "ugh") often ends with a velar fricative.

Examples in English
x
voiceless velar fricative
Ach! [ax]
ɣ
voiced velar fricative
Ugh. [ʊɣ]
Velar fricatives are produced with a constriction between the body of the tongue and the velum, just like velar plosives. In a velar fricative, though, the constriction does not completely cut off airflow from the lungs. Instead, it forces air to move quickly through the constriction, creating turbulent noise. If you produce a [k] sound and release it very slowly, you can hear the sound of a voiceless velar fricative.
Even though they're not phonemes in English, velar fricatives are present as phonemes in several other languages. Arabic, for example, makes use of velar fricatives. The voiceless velar fricative [x] is present in words like khabar ['xabar], meaning news. You can hear the voiced velar fricative in the word balagha [ba'laːɣa], which means rhetoric.
Other Velar Sounds
Plosives and fricatives aren't the only consonants that involve the velum. The structure is necessary for producing other consonants and plays a special role in nasal sounds.
Nasal Sounds
The velum allows you to produce nasal consonants (or nasal stops). Nasal stops are like oral stops; they involve a constriction that keeps air from flowing through the mouth. In a nasal stop, though, the velum lowers to allow air to pass through the nose.
The nasal stops encountered in English are [m], [n], and [ŋ].
IPA Symbol
Articulatory Description
Examples in English
m
bilabial nasal
mime [maɪm], match [mætʃ]
n
alveolar nasal
nose [noʊz], sun [sʌn]
ŋ
velar nasal
sing [sɪŋ], monkey [ˈmʌŋki]
When you produce a velar nasal, your tongue is in the same position as it is for a velar plosive, but your velum itself is lowered. Instead of cutting off the sound, it allows air to continue flowing through your nose.
Have you noticed that when you have a stuffy nose, you can't easily produce sounds like m and n? That's because airflow through the nose is necessary to make these sounds.
Fig. 3 - During nasal stops, the velum lowers to allow air to pass through the nasal cavity.
Other Velar Consonants
The velar plosives, velar fricatives, and velar nasal are some of the most common velar consonants, but there are others that appear in many languages. Here is a more complete list of the velar consonants in the International Phonetic Alphabet.

Velar Fronting
As mentioned earlier, while velar plosives are present in most of the world's languages, they're difficult to produce compared to other plosives. This is because sounds at the back of the mouth require more movement and greater changes in air pressure than sounds at the front of the mouth. Try repeating a [b] sound to yourself as rapidly as possible, and then do the same with a [g] sound. You probably can't produce the [g] sound as quickly or as cleanly as the [b] sound!
Children sometimes have trouble producing velar sounds as they learn to speak and replace them with other sounds closer to the front of the mouth. This pattern is called velar fronting.
Velar fronting is a child speech pattern of replacing velar consonants with more frontal consonants.
A child who uses velar fronting may replace the [g] and [k] sounds with [d] or [t]. They may pronounce grapes as drapes or cup as tup. The pattern of velar fronting usually goes away as the child gets older. If the pattern doesn't seem to go away on its own, a speech-language pathologist can help teach the child to produce velar consonants.
