Catalan is a Romance language spoken by about 9 milion people mainly on the Mediterranean coast of the Iberian Peninsula.
It is an official language, along with Spanish or Castilian, in Catalonia, the Balearic Islands and the Valencian Community (where it is also called Valencian), while it is the only official language of the Principality of Andorra. It is also spoken, and has some administrative recognition, without reaching official status, in the eastern part of the autonomous community of Aragon, in the French department Pyrénées-Orientales (Eastern Pyrenees) and in the city of Alghero, on the island of Sardinia (Italy).
The language evolved from Vulgar Latin in the Middle Ages.

Nord-Occidental [ca-nwestern]: Spoken in Andorra, Lleida and the western half of Tarragona in Catalonia, and the eastern part of Aragon

Una mica les dues coses, ajuda a apropar i acostar algunes persones en segons quins contextos i tens una relació establerta la pot amplificar i la pot magnificar perquè tens accés molt més constant, molt més senzill, molt més fàcil a les relacions, sí. Per altra banda, també té una part aïllacionista, fa que les persones s'individualitzin i que quedin més apartades i ja no vagin a buscar aquestes relacions que altrament podrien estar fent créixer.

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
