Slovene phonology

This article is about the phonology and phonetics of standard Slovene.

Consonants

Slovene has 24 distinctive consonant phonemes; of those, only 21 are more common:

are bilabial, whereas are labiodental.
are dental ; i.e., are laminal denti-alveolar, while are dentalized laminal alveolar, pronounced with the blade of the tongue very close to the upper front teeth, with the tip of the tongue resting behind the lower front teeth.
are alveolar. The first two are laminal denti-alveolar before dental consonants. In addition, is velar before velar consonants, and it merges with to a labiodental before labiodental consonants.
It is debatable whether the Slovene should be transcribed as or. The pronunciation varies between native speakers, but generally they all oppose 'typical' long trill.
is uvular in a number of Upper Carniolan and Carinthian dialects, but such pronunciation is not allowed in Standard Slovene.
is usually pronounced a bit more aspirated and it becomes fully aspirated before close vowels.
is spirantized into in a large portion of the Slovene-speaking area, or even further into or even disappeared altogether.
is usually described as the sequence . Jones found that a vocalic segment similar to occurs before both syllabic and non-syllabic, and that it is shorter than epenthetic, leading to the conclusion that this is not epenthetic, but simply a feature of rhotic consonant production in Slovene.
,, and as a phoneme only appear in loanwords, such as pfenig 'pfennig', sikh 'Sikh', džez 'jazz' and dzeta 'zeta'.

has several allophones depending on context.

Before a vowel, the pronunciation is labiodental,.
Before or after a vowel, the pronunciation is bilabial and forms a diphthong.
At the beginning of a syllable, before a consonant, the pronunciation varies more widely by speaker and area. Some speakers convert into a full vowel in this position. For those speakers that retain a consonantal pronunciation, it pre-labializes the following consonant. Thus, vsi may be pronounced as disyllabic or monosyllabic.
In some dialects turned into instead of // and devoices as a normal obstruent, so vsi would in those dialects be pronounced.

The preposition v is always bound to the following word and it is always pronounced as except when standing alone out of a sentence.
Under certain circumstances, historical at the end of a syllable has become . This change has occurred in the endings of all past participles ending in vowel + l. For many derivatives of words ending in that historically had, both and can be used, sometimes depending on the context it is being used in.
and have different pronunciations before some sonorants:

Before, pronunciation is nasal, and, respectively.
Before and, pronunciation is labiodental, and, respectively.

Similarly, and also change their pronunciations:

Before, the pronunciation is nasal, and, respectively.
Before, they become lateral stops, and, respectively.

Bigger dialectal variations

Slovene has many dialects, which have their own consonant changes. Some of the changes that impact only one consonant are already listed above and more general changes that impact more consonants, as well as two distinctions that are not present in standard language anymore are listed here.

Palatal sonorants

Alpine Slovene, the transitional language between Proto-Slavic and Slovene, had four palatal sonorants: j, ľ, ń, and ŕ. Sonorants, and all turned into sequences, and, respectively if followed by a vowel. Before a consonant, merged with in all dialects, while still retains its palatal pronunciation in Upper Savinja, Inner Carniolan, Karst, Soča, Istrian, Upper Carniolan around Bohinj, South White Carniolan, Kostel and southern part of Gail Valley dialects and retains the pronunciation in Resian, Torre Valley, Natisone Valley, Karst, Inner Carniolan, Istrian, Brda, Soča, Gail Valley, Rosen Valley, Upper Carniolan around Bohinj, Prekmurje, Kostel and South White Carniolan dialects. In other dialects they either merged with their non-palatal counterparts, merged with or turned into sequences and . Therefore, Standard Slovene allows three different pronunciations in this case:

Speakers of dialects which retained original pronunciation usually pronounce them as and, respectively. Elsewhere, this pronunciation is considered archaic.
Speakers of dialects which completely lost the distinction between palatal and non-palatal and pronounce them the same also in the Standard language.
Other speakers can pronounce them either as one of the forms above, or as longer and, respectively.

In the orthography, former, and are always represented by the sequences, and, respectively, except before a consonant is represented by.

tʼ–č distinction

The tʼ–č distinction is one of the two distinctions that was present in Alpine Slovene and is still present in some dialects, but is not present in the standard language anymore. Dialects that still have this distinction mostly do not pronounce the phoneme as anymore, but as, which was also the standard pronunciation during the Reformation. Therefore, this distinction is either dialectal or obsolete. In other dialects, merged with. Examples, where the difference can be observed are sveča 'candle', teči 'to run ' and hočem ' want'.

Shvapanye, elkanye, vekanye and *ł

In Alpine Slavic, *ł was an allophone of *l before consonants, back vowels and, and before a stop. Some dialects still retain the original pronunciation is the pronunciation of and as or before all back vowels, consonants and, which is present in the Carinthian dialects, Upper Carniolan dialect, some northern Lower Carniolan microdialects and the Čabranka dialect. In standard language, shvapanye is only somewhat present, as described above. Elkanye and vekanye is the hypercorrect way of pronouncing words, without shvapanye.

Slekanye

Slekanye is a phenomenon mostly limited to slovenized Germans, which live in around Rut and is the merge of alveolar and post-alveolar fricatives and affricates into one phoneme, which is pronounced somewhere in between. Apart from that area, it is also known for a part of the Torre Valley dialect.

tl/dl–t/d distinction

Proto-Slavic consonant clusters *tl and *dl simplified quite soon in central, southern and eastern areas while it disappeared later from western and northern dialects. Today, the only dialect that still retains this distinction is the Gail Valley dialect. The clusters tl and dl that are nowadays present in the standard language became such after the omission of *ь/*ъ between the consonants. The distinction can be seen in the word vile .

Consonant changes

The pronunciation of a consonant can be influenced by its surroundings, which is not necessarily reflected in the orthography.

First Slavic palatalization

The first Slavic palatalization in nowadays Slovene exists only for,,, and, which turn into,,, and, respectively:

Depalatalized	Palatalized

Second Slavic palatalization

The second Slavic palatalization in today's Slovene exists only for and, which turn into and, respectively:

Depalatalized	Palatalized

Iotation

Iotation is the change of a consonant when follows and they merge in one or more sounds:

Change	Non-iotated	Iotated
→	biti	bič
→	mladiti	mlaj
→	visok	višavje
→	nizek	nižavje
→	jajce	jajčast
→	polniti	polnjen
→	voliti	volja
→	govoriti	govorjen
→	kapati	kaplja
→	pozabiti	pozabljen
→	lomiti	lomljen
→	daviti	davljen
→	frfetati	frflja

Dissimilation

When a stop or affricate is followed by another stop or affricate, it dissimilates into a fricative, e. g. bedak 'idiot' + -ski → bedaš'ki 'idiotic' and k' 'to' + grobu 'grave' → h grobu 'to the grave'.

Assimilation

There are two types of assimilation in Slovene; a consonant can either match the following consonant by voice or by the place of articulation.
All voiced obstruents are devoiced at the end of prosodic words unless immediately followed by a word beginning with a vowel or a voiced consonant. In consonant clusters, voicing distinction is neutralized and all consonants assimilate the voicing of the rightmost segment. The consonant pairs are given in this table:

Devoiced

Voiced

In this context, and may occur as voiced allophones of and, respectively, while and would be hardly ever used allophones of and, respectively. Consonant clusters in non-assimilated words can be excluded from this rule, for example podcast 'podcast'.
When a dental/alevolar fricative or affricate are followed by a postalveolar fricative, affricate or //, they usually become postalveolar; e.g., stric Žan 'uncle, whose name is Žan' or or.
Nasal, also match the place of articulation with the following consonant: Istanbul 'Istanbul', informacija 'information', banka 'bank' .

Gemination of consonants

Several consonant clusters also get simplified into geminated consonants. In fast speech, however, they change into usual, non-geminated consonants.

When two or more of the same consonants are pronounced one after another, they become geminated, taking the allophone of the first one; e.g., brezzob 'toothless'. Stops and affricates can be geminated or pronounced separately; e.g., oddati 'to hand in' or. Labialized consonants can also lose labialization after ; e.g., siv vzorec 'gray pattern' or .
When a dental/alveolar stop is followed by a dental/alveolar affricate, then they can be pronounced separately or combine into a geminated affricate; e.g., od čebele 'from a bee' or.
When a dental/alveolar stop or affricate is followed by a dental/alveolar fricative, they combine into a geminated affricate or are pronounced separately; e.g., podse 'under itself' or.

Vowels

Slovene was long thought to have an eight-vowel system, however newer research suggests that the number of vowels is different between tonal and non-tonal varieties of Slovene which have nine and eleven vowels, respectively.

Stressed front vowels are in most words pronounced as lax when follows, so that, e.g., mira 'myrrh' is pronounced and večer 'evening' is pronounced, but loanwords are exceptions, such as virus and vera.
If a vowel appears at the beginning of a word, a glottal stop is inserted before: ura 'clock, watch', rt 'cape, headland'.
Vowels,, and are pronounced with retracted tongue root while others with advanced tongue root.

Jurgec proposes the existence of a ninth vowel in tonemic variety that in traditional pronunciation would rather be analyzed as a short. However, since more recent studies indicate that native speakers do not actually phonemically distinguish long and short vowels and yet the distinction between and is quite consistently perceived by tonal speakers, and moreover there is a noticeable distinction in quality and a lesser distinction in quantity between these two vowels, there is reason to treat these two sounds as two different phonemes.
The near-open can only appear in the word-final stressed syllable before the syllable coda, as in čas 'time'. Due to the restrictions stated above, the open usually appears in its place in other declinational forms of the same word: časa, not, 'time '. The analysis as two different phonemes is also reinforced by the fact that in some words the phoneme appears in the very same position that would permit, leading to a phonemic contrast: pas, not, 'belt'.
Jurgec also states that in the tonemic varieties of the language, the near-open vowel can carry only the high tone, which is "parallel to the pattern for the ." He also notes that similarly to, the schwa likewise only appears in closed syllables; i.e., as the nucleus before the syllable coda. On the basis of these observations he concludes that the near-open vowel "behaves in a systematic way within the vowel system of Slovenian."
According to, is inserted epenthetically, and its distribution is fully predictable. He also says that "escriptions of schwa distribution are offer in lexical rather than grammatical terms. These were also based on historical data and did not consider actual speech of educated speakers in Ljubljana, nowadays considered standard."
Slovene has been traditionally described as distinguishing vowel length, which correlates with stress and is therefore discussed in the prosody section, below. The distinction between and, and between and is only made when they are stressed and long. When short or unstressed, they are not distinguished: short stressed variants are realized as open-mid, while the unstressed variants are, broadly speaking, true-mid vowels. In fact, however, the unstressed mid vowels have two realizations:

Lowered close-mid before a stressed syllable.
Raised open-mid after a stressed syllable.

The unstressed mid vowels are never as close as the stressed close-mid vowels and never as open as the stressed open-mid vowels. However, report true-mid allophones of the close-mid vowels occurring in the sequences and, but only if a vowel does not follow within the same word. One could therefore argue that the unstressed mid vowels are simply allophones of the close-mid vowels, whereas the open-mid vowels do not occur in unstressed positions. Another argument for transcribing the unstressed mid vowels as is that these symbols are easier to write than. These allophones have neither advanced nor retracted tongue root.
In most cases, unstressed vowels are nowadays written as before the stress and as after the stress; however, an older way of writing them as everywhere is still very common.
In some loanwords, sonorant clusters may be present that are required to form a new syllable in Slovene. Tonal speakers insert, the same way as happens with sonorant + non-sonorant clusters, but non-tonal speakers form a syllabic consonant, except if the second sonorant is ; then is inserted in both varieties: film 'film, movie'.
When unstressed are followed by, they can be pronounced together as.
In non-assimilated loanwords, German,,, are also allowed. When the word becomes assimilated or any affixes are added, they become vernacularized. The pronunciation, however, varies widely between speakers depending on their knowledge of German. Here, the phonemes are given for a really educated person and the first change to go in pronunciation of qualitatively different that.
In the colloquial spoken language, unstressed and most short stressed vowels tend to be reduced or elided. For example, kȕp >, právimo >.

Syllable breaks

Standard Slovene does not really have diphthongs. The closest to a diphthong are combinations of vowel + or. In all other cases, two following vowels form two different syllables, e. g. poenostaviti 'simplify'. Often, these clusters simplify into one vowel or insert or. When two vowels are pronounced one after another, they are usually pronounced as would be expected. Exceptions are unstressed and, which are pronounced as usual or turn into and, respectively if preceded by a vowel, e.g., bo imela ' will have' or.

Dialectal variation

Number of vowels varies drastically between dialects. For example, Tolmin dialect has 3 long vowels, while some Carinthian microdialects can have 15 or even more long vowels. Alpine Slavic had three distinct long e-like vowels and two distinct long o-like vowels and to in the north and east.
While long vowels tend to be diphthongized, short vowels tend to be reduced because of modern vowel reduction, which is also common in colloquial spoken language. Apart from centralization, is commonly pronounced as or as and is commonly pronounced as or .
The most common pronunciation difference between speakers is vs. and vs. as the dialectal distribution is inconsistent with the distribution in Standard Slovene. This influences the way speakers of such dialects speak Standard Slovene.
A new change that is currently happening most notably around Ljubljana is the pronunciation of as or, eliminating another distinction between vowels.

vs.

Historically, is the pronunciation of sem in the meaning 'here' and for sem in the meaning ' am', but due to modern vowel reduction, which is the most prominent in monosyllabic words, and the recent development of →, the roles are nowadays mostly switched, i. e. ' am' is now pronounced and 'here' is now pronounced.

Prosody

Slovene has free stress: stress can occur on any syllable and is not predictable. The same word can be stressed quite differently in different dialects. Most words have a single syllable that carries stress. Some compounds, but not all, have multiple stressed syllables, inherited from the parts that make up the compound. There are also a few small words and clitics, including prepositions, that have no inherent stress at all and attach prosodically to another word.

Vowel length

Slovene is traditionally analysed as having a distinction between long and short vowels. Stress and vowel length are closely intertwined:

A non-final syllable that bears stress will automatically have a long vowel. Conversely, at most one vowel in a Slovene word is long, and it automatically bears the stress.
If a word has no long vowels, the stress usually falls on the final syllable. However, a limited number of words have non-final stress on short syllables.
Schwa can also be stressed non-finally, but has no length distinctions.

Vowel length carries a low functional load: it is distinctive only in stressed final syllables, which can be either long or short. In other syllables, however, whether vowel length or stress, or both, are phonemic depends on the underlying phonological analysis. Generally speaking, stress and length co-occur in all but the final syllable, so one feature or the other is phonetically redundant in those words.
Recently, scholars have found that vowel length in standard Slovene is no longer distinctive, and that the only differences in vowel length are that the stressed vowels are longer than the unstressed ones, and that stressed open syllables are longer than stressed closed syllables. Stressed syllables are characterized by amplitude and pitch prominence.

Accent shifts

Standard Slovene has undergone two accent shifts since Alpine Slovene. The first one, which happened in the 15th century, is from open short final syllables to the mid-close syllable before in words with two syllables, e. g. žena 'wife' →. The original accentuation is retained in a part of Rosen Valley, Resian, Natisone Valley, Torre Valley and southern part of Soča dialects and is considered obsolete in Standard Slovene.
The second accent shift was from short final syllable to the mid vowel in the syllable before, e. g. megla 'fog' → . This change did not happen in all the aforementioned dialects, as well as Upper and Lower Carniolan dialects. Standard language allows both accents, but the unshifted one is considered archaic or high literary, as with the pronunciation of as or, the shift occurs also in Upper and Lower Carniolan dialects.
Other two common accent shifts, that are not present in Standard Slovene are from all short final and from all long circumflex final. The first one happened in Tolmin, Cerkno, Črni Vrh, Horjul, Karst, Inner Carniolan, Istrian, Kostel, Čabranka, South White Carniolan and North White Carniolan dialects, as well as all Styrian dialects, except Lower Sava Valley dialect and the second one happened in Gail Valley dialect without the subdialect, Resian, Torre Valley, Črni Vrh, Poljane, eastern part of Rosen Valley, Jaun, Mežica, North Pohorje–Remšnik, Upper Savinja, Central Savinja, South Pohorje, Kostel, Čabranka, North White Carniolan and South White Carniolan dialects.

Tone

The standard language has two varieties, tonemic and non-tonemic. Tonemic varieties distinguish between two tones or pitch contours on stressed syllables, while non-tonemic varieties do not make this distinction. The tonemic varieties are found in a north–south band in the center of the country. Dialects in the eastern and south-western part of Slovenia are non-tonemic. However, because the Slovenian capital city Ljubljana is located within the central tonemic dialect area, phonemic tone was included in the standard language, and in fact the tonemic variety is more prestigious and is universally used in formal TV and radio broadcasts.
The two tones are:

A low-pitch contour, also known as "acute". It is indicated with an acute diacritic on long syllables, a grave on short syllables.
A high-pitch contour, also known as "circumflex". It is indicated with an inverted breve diacritic on long syllables, a double grave on short syllables.

The exact distribution and phonetic realization of tonemes varies locally. In Standard Slovene, some words may have either an acute or circumflex tone, with the chosen tone differing by speaker. Unless otherwise noted, this article discusses the tonemes as they are realized in Standard Slovene spoken in Ljubljana.
Tone is differentiated only on the stressed and on the last syllables, where it is the opposite of the tone that stressed syllable has. If last syllable is stressed, then they merge and form rising or falling tone; e.g., pot / 'path'. Other vowels have neutral tone. Vowels are mid tone in none-tonemic varieties.
Not all types of syllables have a distinction between the two tones:

All long vowels distinguish the two tones.
Tautosyllabic stressed can also distinguish the two tones. It is considered "long" for this purpose, for example pȓstnica with high/falling tone vs. pŕstanəc with low/rising tone.
For the schwa, the two tones are mostly in complementary distribution: it is circumflex in final syllables and acute elsewhere. This is the only case where a stressed short acute vowel can occur.
All other stressed short vowels are always realised with a circumflex tone. They are mostly restricted to final syllables.

This leads to the following possible combinations of tone, length and vowel quality :

The non-tonemic system is identical to the tonemic system above in terms of vowel length and stress, but lacks any phonemic tone. This means that, for those dialects, the first four rows merge, as do the next three. Similarly, for speakers who do not distinguish short and long vowels, the first and third rows merge, as do the second and fourth. An exception to this is the traditional, which does not merge with. Instead, the former is realized as.

Secondary stress

Longer words, particularly loanwords, also have secondary stress. It always appears in words and word clusters when words do not have primary stress. Secondary stressed is usually every second syllable before and after the syllable with primary stress; e.g., aerofotogrametrija 'aerophotogrammetry'. Secondarily stressed open-mid vowels also become close-mid.
