Sonorant

In phonetics and phonology, a sonorant is a speech sound that is produced without turbulent airflow in the vocal tract; fricatives and plosives are not sonorants. Vowels are sonorants, as are consonants like and . Other consonants, like or , restrict the airflow enough to cause turbulence, and...

		Bilabial Bilabial consonant In phonetics, a bilabial consonant is a consonant articulated with both lips. The bilabial consonants identified by the International Phonetic Alphabet are:...	Alveolar Alveolar consonant Alveolar consonants are articulated with the tongue against or close to the superior alveolar ridge, which is called that because it contains the alveoli of the superior teeth...		Palatal Palatal consonant Palatal consonants are consonants articulated with the body of the tongue raised against the hard palate...	Velar Velar consonant Velars are consonants articulated with the back part of the tongue against the soft palate, the back part of the roof of the mouth, known also as the velum)....		Labial- velar Labial-velar consonant Labial–velar consonants are doubly articulated at the velum and the lips. They are sometimes called "labiovelar consonants", a term that can also refer to labialized velars, such as and the approximant ....
			central Central consonant A central or medial consonant is a consonant sound that is produced when air flows across the center of the mouth over the tongue. The class contrasts with lateral consonants, in which air flows over the sides of the tongue rather than down its center....	lateral Lateral consonant A lateral is an el-like consonant, in which airstream proceeds along the sides of the tongue, but is blocked by the tongue from going through the middle of the mouth....		plain	lab. Labialisation Labialization is a secondary articulatory feature of sounds in some languages. Labialized sounds involve the lips while the remainder of the oral cavity produces another sound. The term is normally restricted to consonants. When vowels involve the lips, they are called rounded.The most common...
Plosive Stop consonant In phonetics, a plosive, also known as an occlusive or an oral stop, is a stop consonant in which the vocal tract is blocked so that all airflow ceases. The occlusion may be done with the tongue , lips , and &...	voiceless Voiceless In linguistics, voicelessness is the property of sounds being pronounced without the larynx vibrating. Phonologically, this is a type of phonation, which contrasts with other states of the larynx, but some object that the word "phonation" implies voicing, and that voicelessness is the lack of...	p	t			k	kʷ	k͡p
	voiced Voice (phonetics) Voice or voicing is a term used in phonetics and phonology to characterize speech sounds, with sounds described as either voiceless or voiced. The term, however, is used to refer to two separate concepts. Voicing can refer to the articulatory process in which the vocal cords vibrate...	b	d			ɡ	ɡʷ	ɡ͡b
Fricative Fricative consonant Fricatives are consonants produced by forcing air through a narrow channel made by placing two articulators close together. These may be the lower lip against the upper teeth, in the case of ; the back of the tongue against the soft palate, in the case of German , the final consonant of Bach; or...	voiceless		s

Approximant Approximant consonant Approximants are speech sounds that involve the articulators approaching each other but not narrowly enough or with enough articulatory precision to create turbulent airflow. Therefore, approximants fall between fricatives, which do produce a turbulent airstream, and vowels, which produce no...	voiceless			l̥	ȷ̊		w̥

A glottal stop [ʔ] appears before any otherwise vowel-initial stem. The alveolar consonants are apical.

Tẹẹ includes a rather unusual series of voiceless sonorant

Sonorant

In phonetics and phonology, a sonorant is a speech sound that is produced without turbulent airflow in the vocal tract; fricatives and plosives are not sonorants. Vowels are sonorants, as are consonants like and . Other consonants, like or , restrict the airflow enough to cause turbulence, and...

Voiceless palatal fricative

The voiceless palatal fricative is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is . The symbol ç is the letter c with a cedilla, as used to spell French words such as façade...

 [ç], but is not as noisy (that is, there is not much random-frequency noise in its sound spectrum). Similarly, /l̥/ is a voiceless approximant, not a voiceless fricative

Voiceless alveolar lateral fricative

The voiceless alveolar lateral fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents voiceless dental, alveolar, and postalveolar fricatives is , and the equivalent X-SAMPA symbol is K...

 *[ɬ]. The voiceless bilabial nasal, /m̥/, is only known to occur in one word, /àm̥èː/ (an unidentified abdominal organ), and then only for some speakers. All of the voiceless sonorants are actually voiced during the second half of their enunciation. That is, /n̥/ is pronounced [n̥͡n] However, they are considerably shorter than their voiced homologues, and hence cannot be considered /hC

Consonant

In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract. Examples are , pronounced with the lips; , pronounced with the front of the tongue; , pronounced with the back of the tongue; , pronounced in the throat; and ,...
