Inuit phonology

This article discusses the phonology of the Inuit languages. Unless otherwise noted, statements refer to Inuktitut dialects of Canada.
Most Inuit varieties have fifteen consonants and three vowel qualities. Although Inupiatun and Qawiaraq have retroflex consonants, retroflexes have otherwise disappeared in all the Canadian and Greenlandic dialects.

Vowels

Almost all dialects of Inuktitut have three vowel qualities and make a phonemic distinction between short and long vowels. In Inuujingajut long vowels are written as a double vowel.

IPA	Inuujingajut

	aa
	i
	ii

	uu

In western Alaska, Qawiaraq and to some degree the Malimiutun variant of Inupiatun retains an additional vowel which was present in proto-Inuit and is still present in Yupik, but which has become or sometimes in all other dialects. Thus, the common Inuktitut word for water – imiq – is emeq in Qawiaraq.
Furthermore, many diphthongs in the Alaskan dialects have merged, suggesting the beginnings of a new more complex vowel scheme with more than three distinct vowels. This phenomenon is particularly noticeable in the Kobuk area, where the diphthongs and are now both pronounced. Other diphthongs are also affected.
In contrast to the larger number of vowel contrasts in Alaskan dialects, in the dialect of northwest Greenland, the phoneme has been replaced by in many contexts.
Otherwise, the three-vowel scheme described above holds for all of the Inuktitut dialects.
West Greenlandic vowels have a very wide range of allophones:

Consonants

The Nunavut dialects of Inuktitut have fifteen distinct consonants, though some have more.

Stress

Primary stress is said to fall on the last syllable of each word.

Intonation

In Inuktitut, intonation is important in distinguishing some words – particularly interrogatives – but it is not generally marked in writing. There are some minimal pairs in Inuktitut where only pitch distinguishes between two different words, but they are rare enough that context usually disambiguates them in writing. One common case, however, is suva. A high pitch on the first syllable followed by a falling pitch on the second syllable means "What did you say?" A middle pitch on the first syllable followed by a rising pitch on the second means "What did he do?"
In general, Inuktitut uses intonation to mark questions in much the way English does. When an interrogative pronoun is used, pitch falls at the end of a question. When there is no interrogative pronoun, pitch rises on the last syllable.
Inuktitut speakers tend to lengthen vowels with a rising intonation. So, a rising tone is sometimes indicated indirectly by writing a double vowel:

Phonotactics and sandhi

An Inuktitut syllable contains no more than one segment in the onset or coda. Thus, consonant clusters like or that would arise from morphemes being joined together show assimilation or deletion. Word-finally, only voiceless stops occur unless consonant sandhi has occurred. Although two-consonant sequences occur when morphemes are joined together word-medially, three-segment clusters are consistently simplified.
Word-medially, two-segment sequences may occur, but these show restrictions in their distribution, based on voicing and nasality. The consonants that occur in these sequences belong to three groups:
Consonants in word-medial sequences always belong to the same group so that, e.g.,, and occur, whereas,, and are not found. Where the morphology of Inuktitut places consonants from different groups together, they are either replaced by a geminated consonant – in effect, total assimilation – or as a single consonant that takes its manner of articulation from one segment, and its place of articulation from the other. The process of eliminating three-segment clusters is similar with one of them disappearing. As a general rule, assimilation in Inuktitut is regressive – the first consonant takes its manner of articulation from the second consonant. But this varies amongst different dialects; the West Greenland dialect in particular tends to use progressive assimilation – the second consonant takes the manner of articulation from the first.
This limitation on consonant clusters is not quite universal across Inuit areas. One of the distinguishing features of western Alaskan dialects like Qawiaraq and Malimiutun is that nasal consonants can appear after consonants with other manners of articulation. Some examples include the Malimiut word qipmiq and the Qawiaraq word iqniq.
Otherwise, different dialects have more phonotactic restrictions. In all forms of Inuktitut, is impossible. In Inupiatun, Siglitun, and Inuinnaqtun, all other consonant pairs are possible. Moving further east, the general rule is that more and more double consonants become geminated consonants. Determining which double consonants are assimilated depends on the place of articulation of the first consonant in the pair:
In the Aivilik dialect, North and South Baffin, and all dialects spoken further south and east, all double consonants starting with an alveolar consonant are geminated:

Dialect	word
Sew Inupiatunivlin	ivlin
Inupiatun	ilvich
Siglitun	ilvit
Inuinnaqtun	ilvit
Natsilingmiutut	ilvit
Kivallirmiutut	igvit
Aivilingmiutut	igvit
North Baffin	ivvit
South Baffin/Nunavik	ivvit
Labrador	iffit
Kalaallihut Inuktun	iglit
Kalaallisut	illit
East Kalaattisit	ittit

In the North and South Baffin dialects, as well as the dialects to the south and east of Baffin Island, double consonants starting with a labial consonant are also geminated. E.g. North Baffin takagakku vs. Aivilingmiutut takugapku
In South Baffin, Nunavik, Greenland and Labrador, double consonants starting with a velar consonant are also geminated:

English	Inupiatun	Inuinnaqtun	Aivilingmiutut	North Baffin	South Baffin	Nunatsiavummiutut	Kalaallisut	East Kalaattisit
house	iglu	iglu	iglu	iglu	illu	illuK^[\|1]	illu	ittiq

In addition, some dialects of Inuktitut pronounce in place of the geminated lateral approximant. The phonological status of this distinction is uncertain – some dialects have both and. This feature is generally characteristic of western and central dialects as opposed to eastern ones.

thumb	kuvlu	kublu	kublu	kullu	kullu	[\|kulluK]¹	kulloq¹	tikkit

Note 1 [|qitilliK], kulluK, kulloq: In the Nunatsiavummiutut alphabet, a capital K indicates the same uvular stop as q in the Inupiatun, Inuinnaqtun, Kalaallisut and Nunavut alphabets. Furthermore, o in the Kalaallisut alphabet represents the same phoneme as u in the alphabets used for other varieties of Inuktitut. Contrasts between alphabets are described below.
Double consonants where the second consonant is undergo more complex changes across dialects. In some cases assimilation is progressive, in others regressive, and in still others double consonants are neutralised into a single form.

Other systematic dialectical variations

Consonant weakening in Qawiaraq

Many phonemes in the Qawiaraq dialect have undergone a process of consonant weakening, although to what degree varies somewhat between villages. This process is motivated in part by prosody and parallels the consonant weakening processes at work in Yupik. As a result, many stops have become fricatives and many fricatives have become glides or completely disappeared. For example, the word meat – niqi in most dialects – is rendered as nigi in Qawiaraq – the stop has become the fricative.
Consonant weakening is most noticeable in the area adjacent to the Bering Strait in the westernmost part of Alaska.

Palatalization in Inupiatun

The historical fourth vowel of Inuktitut – the schwa – affected the pronunciation of alveolar consonants following it. Where an was present in proto-Inuktitut, the following consonant is palatalized in modern Inupiatun. Thus, for example, becomes, spelled ch alone and tch when geminated, after some i but not others. For example, the second person singular pronoun ilvit – you – in more easterly dialects of Inuktitut becomes ilvich in Inupiatun. In contrast, iqit, which was pronounced in proto-Inuktitut, retains its stop.
Similar processes affect other alveolar consonants:

Alveolar consonant	Palatal consonant	Inupiatun spelling	Example
		ch	ilvit → ilvich
		ñ	inuk → iñuk
		ḷ	silami → siḷami

In the Malimiut variant of Inupiatun, this process is extended to some velar consonants, like and.

Assibilation

In a number of dialects, preceded by an derived from an * in Proto-Inuktitut rather than an * may become an when followed by another vowel:

English	Inupiatun	Siglitun	Natsilingmiutut	Kivallirmiutut	North Baffin	Kalaallisut
he/she comes in	isiqtuq	itiqtuaq	ihiqtuq	itiqtuq	isiqtuq	iserpoq

This feature varies from dialect to dialect and does not follow a consistent east/west pattern, as assibilation is present in some words in both Alaskan Inupiatun and Greenlandic Kalaallisut. The exact conditions in which Proto-Inuktitut consonants have been assibilated vary from dialect to dialect, often determined by the following vowel and other factors.

Fricative substitution in western Nunavut

Many of the western and central dialects of Nunavut – including Inuinnaqtun, Kivallirmiutut and Natsilingmiutut – realize the phoneme as. Inuinnaqtun also pronounces as. This leads to an additional constraint on double consonants in Inuinnaqtun: a stop followed by the fricative becomes a fricative at the same point of articulation. This feature does not extend west of Inuinnaqtun and is not present in Siglitun or Inupiatun.

English	Inuinnaqtun	Kivallirmiutut	North Baffin
egg	ikhi	ikhi	iksi
blubber	uqhuq	uqhuq	uqsuq
walking	pihukhuni	pihukhuni	pisukɬuni

Retroflex consonants in western dialects

Natsilingmiutut retains as a phoneme the stop, and often retroflex, palatal consonant. This consonant has merged with in all other Nunavut and eastern dialects of Inuktitut. In Inupiatun, the of Natsilingmiutut and the in some central Inuktitut words has become .

English	Inupiatun	Natsilingmiutut	North Baffin	Itivimiutut	Kalaallisut
eye	iri	iri	iji	iri	isi
kayak	qayaq	qajaq	qajaq	qaraq	qajaq
big	angiruq	angiruq	angijuq	angiruq	angivoq

In addition to the voiced retroflex fricative, Inupiatun also has a voiceless retroflex fricative represented as. This additional manner of articulation is largely distinctive to Inupiatun – it is absent from the more easterly dialects, except for the of Natsilingmiutut.

English	Qawiaraq	Inupiatun	Siglitun	Natsilingmiutut	North Baffin	Kalaallisut
spider	aachivak	aasrivak	aasivak	aahivak	aasivaq	aasiak
penis	uchuk	usruk	usuk	uhuk	usuk	usuk

The Qawiaraq dialect of Inupiatun, furthermore, has a third retroflex consonant in addition to the two present in other varieties of Inupiatun: the retroflex approximant.

Double consonant clusters in Nunavimmiutut

Nunavik Inuktitut, in contrast to other dialects, does not allow two double consonants to appear with only one syllable between them. Wherever this occurs, the first consonant in the second consonant pair is deleted.

English	North Baffin	Nunavimmiutut
calendar	ulluqsiut	ullusiut
he is coughing	quiqtuqtuq	quiqtutuq

Glottal stops

In a number of dialects, uvular consonants and ordinary stops are replaced with glottal stops in some contexts. Which uvular consonants and which contexts varies to some degree across dialects. Most frequently, a or in some cases a before another consonant is transformed into a glottal stop. Thus, the Inuktitut name of the hamlet of Baker Lake is pronounced Qamaniqtuaq or Qamanittuaq by most Inuktitut speakers, but is rendered Qamani'tuaq in Baker Lake itself. This phenomenon occurs in a number of dialects, but is particularly noticeable in Nunavimmiutut and in central Nunavut dialects like Kivallirmiutut.
In Natsilingmiutut, the velar nasal consonant sometimes becomes a glottal stop when followed by another consonant, but not in all cases.
