nn-NO)This datasheet is for version 23.0 of the the Mozilla Common Voice Scripted Speech dataset
for Norwegian Nynorsk (nn-NO). The dataset contains 1.7 hours of recorded
speech (1.5 hours validated) from 40 speakers.
Norwegian Nynorsk is a written standard of Norwegian. The standard is the preferred written standard of around 10-15% of the Norwegian population and is largely based on the Norwegian dialects of the West of Norway.
The language code is nn and the locale is nn-NO (Nynorsk as written in Norway). Note that this
locale includes the region code for historical reasons relating to the localisation platform. The dataset
contains Norwegian as spoken anywhere and as written in the Nynorsk standard.

Korpus med bokomtalar frå Bokelskere.no (Public domain)
Stortingskorpuset 1.1 (Public domain)
Individual sentences submitted by users through the Mozilla Common Voice interface (Public domain)
The corpus was initially seeded with sentences from
Book reviews and book discussions (from the web community bokelskere.no)
Transcribed and manually checked discussions from the Norwegian Parliament (Stortinget), from 2017 to 2018
Later, several individual users have contributed sentences in various domains through Mozilla's web interface.
Both sources include sentences in both Norwegian Nynorsk and Norwegian Bokmål.
Norwegian Nynorsk candidate sentences were extracted by both excluding Bokmål-only words and including Nynorsk-only words:
| Only | Words |
|---|---|
| Bokmål | ikke, jeg, en, et, fra, hun, noen, være, mer, ble, mye, bare, boken, kommer, flere, dem |
| Nynorsk | eg, ikkje, ein, me, vere, meir, fleire, berre, ho, eit, blei, vart |
These candidate sentences were then checked by two writers of Nynorsk to ensure that they were indeed written in Nynorsk before inclusion into the corpus.
