Yaqui (or Hiaki), locally known as Yoeme or Yoem Noki, is a Native American language of the Uto-Aztecan family. It is spoken by about 20,000 Yaqui people, in the Mexican state of Sonora and across the border in Arizona in the United States. It is partially intelligible with the Mayo language, also spoken in Sonora, and together they are called Cahitan languages. Phonology The remarks below use the orthography used by the Pascua Yaqui Tribe in the United States. There are also several orthographic systems used in Mexico differing slightly, mainly in using Spanish values for several consonants and Spanish spelling rules: "rohikte" would be written "rojicte". There are minor differences in the sounds of Mexican and American dialects, the latter tending to exclude an intervocalic "r" and final "k". Vowels Yaqui vowel sounds are similar to those of Spanish: Vowels may be either short or long in duration. Often, long vowels are shortened when the word they are used in is used constructively: 'maaso' ('deer') is shortened to 'maso' in 'maso bwikam' ('deer songs'). Long vowels are written by doubling the vowel. Long vowels may change tone, but that is not represented in the written language. Yaqui has often been described as being a tonal or "pitch accent" language, but the modern forms of the language do not show any widespread and significant use of tonemes. Consonants The following consonantal sounds are present in Yaqui: b, ch, (d), (f), (g), h, k, l, m, n, p, r, s, t, v, w, y, and one or two glottal stops (IPA ), represented by an apostrophe. Except for the glottal stops, most of them are pronounced nearly the same as they are in English, but "p", "t", and "k" are not aspirated. In the IPA, they are respectively . Many Yaqui-speakers pronounce b and v exactly the same, as . That appears to be intrinsic to Yaqui, rather than from the influence of Spanish, which has a similar feature. Additionally, there are two consonants written as clusters: "bw" (IPA ) and "kt" (IPA ), "bw" being a rounded "b" ('bwikam') and "kt" a simultaneous articulation of "k" and "t" ('rohikte'). The "kt" sound is found in many other Uto-Aztecan languages. Pronunciation of the rounded "b" as "b"+"w" and the "kt" as "k"+"t" is acceptable but non-native. Also, "d", "f", and "g" are present only in English and Spanish loanwords and are
