Common Voice Spontaneous Speech 3.0 - Galician

Galego — Galician (gl)

This datasheet is for sps-corpus-3.0-2026-03-09 of the Mozilla Common Voice Spontaneous Speech dataset for Galician [Galego - gl]. The dataset contains 2180 clips representing 5.14 hours of recorded speech (0.32 hours validated) from 109 speakers.

Language

Galician is the language of Galicia (Spain). In addition to being a language of use in this territory, it is spoken in other bordering areas, although without official status (Asturias, León, Zamora). It belongs to the Indo-European language family, specifically the Romance languages, along with Spanish, Portuguese and Catalan. It also has a close relationship with Portuguese since they share historical origins, but today they constitute two separate languages with each one having its own respective standard. The state of vitality of the language is “Institutional” according to Ethnologue https://www.ethnologue.com/language/glg/, that is, the language is developed, has a standard variety, is taught at all stages of the Galician educational system and has institutional support. However, from the point of view of sociolinguistics, both the autonomous community of Galicia and the other territories that speak the Galician language present typical features of a situation of linguistic conflict (diglossia), resulting from a historical process of replacement of Galician (a minority language) by Spanish.

The Galician language is a rich and diverse reality, and its linguistic variation is manifested in spontaneous speech. Thus, aspects such as age, geography, sociocultural level or communicative context also influence linguistic uses. At the dialectal level, Galician presents differentiating features between the eastern and western areas, as well as between the north and the south: phonetic changes (such as the use of gheada or seseo), lexical variations (different words to designate the same object) or even small morpho-syntactic differences.

Data splits for modelling

Writing system

The writing system of Galician is based on the Latin alphabet, like other Romance languages (Spanish, Portuguese or French). Its orthography is regulated by the corresponding regional institutions that establish the official rules of use (NOMIG).

Galician uses the 23 letters of the basic Latin alphabet: 5 vowels (a, e, i, o, u) and 18 consonants. The vowel system of Galician is composed of seven oral vowels (/a/, /e/, /ɛ/, /i/, /o/, /ɔ/ and /u/), as the mid vowels ("e" and "o") have two possible pronunciations: open (/ɛ/, /ɔ/) and closed (/e/, /o/). At the consonant level, the letters Ç, J, K, W and Y are supported in foreign words, proper names, abbreviations and international acronyms. The Galician alphabet also has numerous digraphs: combinations of two letters that represent a single sound: "ch", "gu", "ll", "nh", "qu", "rr". In addition, the presence of the phoneme /ʃ/ represented by the letter “x”, the fricative sound /ʒ/, the distinction between /s/ and /θ/ which depends on the dialect areas, the gheada, etc., should be highlighted in the Galician consonant system.

Accentuation in Galician is quite regular and follows clear rules. A graphic "diacritical accent" is also used to distinguish pairs of words with the same spelling but different meanings, e.g., bóla (sphere, ball), bola (round type of bread).
