About Uzbek transcription
Uzbek (Oʻzbekcha) is written in the Latin alphabet and spoken principally in Uzbekistan. Subtitles generated here come back in that script, as ordinary written Uzbek, ready to use in an SRT or VTT file.
Uzbek is transcribed here in the Latin alphabet, now the official script, though Cyrillic remains in everyday use and older material is written in it. Unlike its Turkic neighbours it has largely lost vowel harmony, and Russian is mixed into urban speech routinely.
