About Asturian transcription
Asturian (Asturianu) is written in the Latin alphabet and spoken principally in Asturias, in northern Spain. Subtitles generated here come back in that script, as ordinary written Asturian, ready to use in an SRT or VTT file.
Asturian sits close enough to Spanish that automatic detection struggles between them, and most speakers move fluidly between the two within a conversation. Choosing Asturian explicitly is what keeps its own vocabulary and endings in the transcript instead of them being normalised toward Castilian.
