Latvian phonology


This article is about the phonology of Latvian. It deals with synchronic phonology as well as phonetics.

Consonants

Table adopted from
  • are denti-alveolar, while are alveolar.
  • The consonant sounds are only found in loanwords.
  • is only an allophone of nasals before velars and.
  • Latvian plosives are not aspirated.
  • Voiced and voiceless consonants assimilate to the subsequent consonant, e.g. apgabals or labs.
  • Voiced consonants are not devoiced word-finally: dzied, dedz.
  • Consonants can be short or long; long consonants are represented with double letters in the orthography: mamma.
  • Plosives and fricatives that occur between two short vowels are lengthened, as in upe, and words spelt with ⟨zs⟩, pronounced as, or ⟨šs⟩ or ⟨žs⟩, both pronounced as .
  • A palatalized dental trill is still used in some dialects but quite rarely, and hence the letter was removed from the alphabet.

Vowels

Latvian has six vowels, with length as distinctive feature:
, and the diphthongs involving it other than, are confined to loanwords.
The vowel length ratio is about 1:2.5. Vowel length is phonemic and plays an important role in the language. For example, koka means 'made of wood', kokā means 'on the tree'; pile means 'a drop', and pīle means 'a duck'.
Latvian also has 10 diphthongs, although some diphthongs are mostly limited to proper names and interjections.

Pitch accent

Standard Latvian and, with a few minor exceptions, all of the Latvian dialects, have fixed initial stress. Long vowels and diphthongs have a tone, regardless of their position in the word. This includes the so-called "mixed diphthongs", composed of a short vowel followed by a sonorant. There are three types of tones:
; level tone
; falling tone
; broken tone
Besides the three-tone system of the standard variety, there are also Latvian dialects with only two tones: in western parts of Latvia, the falling tone has merged with the broken tone, while in eastern parts of Latvia the level tone has merged with the falling tone. Hence, the Central Latvian traũks, dràugs, raûgs correspond to Western Latvian traũks, draûgs, raûgs, and to Eastern Latvian tràuks, dràugs, raûgs.
This system is phonetically more or less similar to the ones found in Lithuanian, Swedish, Norwegian and Serbo-Croatian. The broken tone has some similarity to the Danish stød.

Alternations

Latvian roots may alternate between and depending on whether the following segment is a vowel or a consonant. For example, the root Daugav- in the nominative case is, but is pronounced in the city name Daugavpils. In this example, the vocalic alternant is realized as the off-glide of the diphthong. However, when following a vowel that does not form an attested Latvian diphthong, is pronounced as a monophthong, as in .
