let's go! can be [maˈji] or [maˈʒi]. [ʔj] can become [ʔd͡ʒ] word initially: I am afraid can be [ˈʔjinʔ ʔiˌna] or [ˈʔd͡ʒinʔ ʔiˌna]. Vowels Wariʼ has one of the world's most asymmetrical vowel systems. Vowels are generally expected to be somewhat evenly distributed in the vowel space, not bunched into a corner. Additionally, vowels are expected to be unrounded when front and rounded when back until "gaps" in the vowel system have been filled. Although Wariʼ has only six vowels, four of these are close/close-mid front vowels, of which two are rounded (although is uncommon). Non-native speakers have marked difficulty in distinguishing these front vowels, that contrast with only a single back vowel . Vowel nasalisation occurs on diphthongs only; the few which are not nasalised all end in /i/. The following diphthongs occur in the Oro Nao dialect: [ẽĩ], [ãĩ], [aɪ], [õĩ], [oɪ], [ỹĩ], [ĩõ], [ẽõ], [ãõ]. Vowel Alternations can become in unstressed syllables if the vowel in the following syllable is : it is rocking can be [pikiˈɾim na] or [pɪkɪˈɾim na]. /e/ becomes before all stops other than [ʔ], and in unstressed syllables in harmony with /e/ becoming in the stressed syllable: day is [t͡ʃɛk] because of the [k], and they went out is [hʷɛɾɛˌhʷɛt maˈmaʔ naˌna] because the [t] in the stressed syllable causes /e/ to become and the preceding ones change in harmony. /e/ becomes before nasals, and in harmony with a /e/ becoming in the stressed syllable: it is numb is [tɪtɪˈɾɪn na]. can become in unstressed syllables when the vowel in the stressed syllable is not : its seed can be [toˈkʷi] or [tʊˈkʷi]. is a rare segment and for some speakers is evolving into in open syllables and in closed ones. Syllables The basic syllable in Wari' is CV(C), but suffixes can be of the form VC, VCVC or V. Only stops and nasals can occur in syllable codas. Consonant clusters are rare: /n/ is the only first segment found, and /t/, /k/ and /t͡ʃ/ are the only second segments found in non-compound words. Wariʼ has words ending in the consonant clusters and . These have been analysed as single sounds, but apparently only to avoid complicating syllable structure. If these are separate phonemes, these clusters only occur word finally. In the Oro Nao dialect, many consonants alternate with [ʔC] at the beginning of monosyllabic words, and always precedes word initial semivowels
