Wari’ has two phonetic oddities: its "skewed" vowel inventory, and the voiceless dental bilabially trilled affricate [t͡ʙ̥], which is only reported from four other languages, and is only phonemic in Wari' and two neighbouring languages.

Sounds

Wari’ syllables range in complexity from CV to CVVC. The only exceptions appear to be final consonant clusters involving a glottal stop (see below).

Consonants

	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:...	Dental	Post- alveolar Postalveolar consonant Postalveolar consonants are consonants articulated with the tongue near or touching the back of the alveolar ridge, further back in the mouth than the alveolar consonants, which are at the ridge itself, but not as far back as 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)....		Glottal Glottal consonant Glottal consonants, also called laryngeal consonants, are consonants articulated with the glottis. Many phoneticians consider them, or at least the so-called fricative, to be transitional states of the glottis without a point of articulation as other consonants have; in fact, some do not consider...

Therefore, approximants fall between fricatives, which do produce a turbulent airstream, and vowels, which produce no...			j		w	h

 preceded by a dental stop, forming a single unit. Only about 24 words contain the sound, some of which are onomatopoeic.

Wari’ has words ending in consonant clusters mʔ and nʔ. These have been analysed as single sounds, but apparently only to avoid complicating the Wari’ syllable structure.

Vowels

Vowels are generally expected to be somewhat evenly distributed in vowel space (that is, spread out rather than bunched up when represented on a vowel chart). Additionally, when a language has few vowels, they will normally be unrounded when front and rounded when back. Usually rounded front vowels and unrounded back vowels are only found in languages with large inventories such as German

. However, while Wari’ has only six vowels, four of these are high/mid front vowels, of which two are rounded (although /ø/ is somewhat rare). These contrast to only a single back vowel. The front vowels are so close that it is sometimes difficult for a non-native speaker to distinguish them. This results in what is probably the most asymmetrical vowel system known.

	Front Front vowel A front vowel is a type of vowel sound used in some spoken languages. The defining characteristic of a front vowel is that the tongue is positioned as far in front as possible in the mouth without creating a constriction that would be classified as a consonant. Front vowels are sometimes also...		Back Back vowel A back vowel is a type of vowel sound used in spoken languages. The defining characteristic of a back vowel is that the tongue is positioned as far back as possible in the mouth without creating a constriction that would be classified as a consonant. Back vowels are sometimes also called dark...
