This dataset is intended to be used for training and evaluating automatic speech recognition (ASR) models. It may also be used for applications relating to computer-aided language learning (CALL) and language or heritage revitalisation.
lv)This datasheet is for sps-corpus-4.0-2026-06-12 of the Mozilla Common Voice Spontaneous Speech dataset for Latvian [Latviešu - lv]. The dataset contains 62 clips representing 0.58 hours of recorded speech (0.08 hours validated) from 9 speakers.
Latvian is an Baltic language belonging to the Indo-European language family. It is spoken in the Baltic region, and is the official language of Latvia as well as one of the official languages of the European Union. There are about 1.5 million native Latvian speakers in Latvia and 100,000 abroad. It uses the Latin alphabet with additional diacritical marks to represent specific sounds.
There are slight stylistic speach variations among different regions of Latvia, but they do not affect mutual
intelligibility. Latgale region has more significant differences with main Latvian language. It is sometimes
considered a dialect, but Latgalian (ltg) speech is collected as a separate language in Common Voice.
The dataset clips are categorised by transcription status and training-set assignment. The following tables summarise the distribution.

Latvian alphabet is based on the Latin script and consists of 33 letters, including special characters with diacritical marks such as ā, č, ē, ģ, ī, ķ, ļ, ņ, š, ū, and ž.
Historic texts also used letter /ŗ/, but use of it has been officially discontinued since 1946. This letter is equivalent to letter /r/ in modern Latvian orthography.
Letter /o/ can represent three different sounds [ua̯], [ɔ], [ɔː].
Letter /e/ can represent two different sounds [e], [æ].

Visvairāk es lepojos ar to, ka man ir ģimene, kura mani mīl, ka man ir draugi, ar kuriem es varu pastāvīgi sarunāties - jebkad, par ko. Ir daudzas lietas, par kurām es savā dzīvē lepojos. Es arī lepojos arī par to, ka esmu izaudzis ar pietiekami lielu pacietību, lai, lai sasniegtu savus mērķus.
Es tā baigi nelietoju kaut kādas dziedniecības metodes, bet, protams, kaut kādas zāļu tējas sanāk tur dzert - kumelīšu, liepziedu. Nu jā, kaut kādas tādas.
Tāds konkrēts datums varbūt pat nav noteikts. Man ļoti patīk mana dzimšanas diena, kas ir sešpadsmitajā aprīlī. Tie ir svētki. Tas ir tik daudz pozitīva vienā dienā. Redzēt savus mīļos cilvēkus, ēst, svinēt, nu tas ir, man liekas, ļoti, ļoti forši. Uzņemt ciemiņus arī, jā, man ļoti patīk.
Ļoti skaista vieta Latvijā ir Ogrē, Zilie kalni. Tur ir skatu tornis un fantastiskas takas. Tās var izbraukt ar elektroriteni vai arī vienkārši, ar kājām pastaigājoties. Var arī iet pa mazajām taciņām, kas nav populārās, un tad ir neticami skaisti skati. Pa ceļam var salasīt meža zemenes šobrīd, kas ir jūlijā, mellenes, gailenes. Noteikti jāiet ir ar maisiņu! Bet, jā. Skaisti smaržo mežs, nav pārāk blīvs ar cilvēkiem. Jā, perfekta, perfekta pastaigu taka, kur iekšā arī ir kariers, kurā var nopeldēties, ar dzidru, skaistu ūdeni. Tā kā to rekomendēju noteikti Latvijā apmeklēt.
Klasiskajā brīvdienā notiek mājas uzkopšana, piemēram, mazgājot veļu. Kā arī es studēju un tāpēc brīvdienas bieži vien aiziet studiju darbu pildīšanā.
Each row of a tsv file represents a single audio clip, and contains the following information:
client_id - hashed UUID of a given user
audio_id - numeric id for audio file
audio_file - audio file name
duration_ms - duration of audio in milliseconds
prompt_id - numeric id for prompt
prompt - question for user
transcription - transcription of the audio response
votes - number of people that who approved a given transcript
age - age of the speaker1
gender - gender of the speaker1
language - language name
split - for data modelling, which subset of the data does this clip pertain to
char_per_sec - how many characters of transcription per second of audio
quality_tags - some automated assessment of the transcription--audio pair, separated by |
transcription-length - character per second under 3 characters per second
speech-rate - characters per second over 30 characters per second
short-audio - audio length under 2 seconds
long-audio - audio length over 5 minutes
non-allowed-script - transcription contains characters from a writing system not associated with the language
mixed-script-words - a single word contains characters from multiple writing systems
mixed-script-transcription - transcription spans multiple writing systems, but each word consistently uses only one
