Translate subtitles
to Bulgarian

How it works for Bulgarian

Upload an English .srt or .vtt file, or a season as a zip. Cues travel to the model in batches of 32 so a sentence that spans two cues is translated as one thought. Every Bulgarian cue then passes thirteen structural checks; whatever fails goes back with the exact complaint attached, and an editor pass sweeps the whole file for register and idiom. You download the subtitles and a quality report, and the upload is deleted.

What the Bulgarian profile checks

• A wordlist of 47 Russian words spelled entirely in Bulgarian letters (медленно, глубоко, сейчас), plus 63 Bulgarian function words the output must contain. A character-set check alone passes Russian as Bulgarian.
• ти and вие are inferred from the surrounding cues and held for each pair of speakers. Measured on a real episode: zero cues mixed forms of address.
• „…“ quotation marks by instruction, and the closing mark counts as sentence-ending so a correctly quoted line is not flagged as unfinished.
• Files in Windows-1251 and frame-based MicroDVD .sub are read correctly; a .sub file's declared frame rate is used rather than guessed.
• Scored 48.94 chrF++ against a professional human translation of four episodes, the mean of three runs.

Sound labels, from the table

Labels for the deaf and hard of hearing are resolved from a fixed Bulgariantable before the model sees the text, so they are never invented. Three entries, exactly as the table renders them:

[LAUGHS]

[СЕ СМЕЕ]

[DOOR CLOSES]

[ВРАТАТА СЕ ЗАТВАРЯ]

[PHONE RINGS]

[ТЕЛЕФОНЪТ ЗВЪНИ]

Is Bulgarian measured?

Bulgarian has a measured baseline: 48.94 chrF++ against a professional human translation, over 1,236 aligned units (mean of 3 runs). That figure is what every change to the pipeline has to beat for Bulgarian. It is not comparable to another language's figure; here is why.

Price and time

One credit translates about 20,000 characters of dialogue, roughly a 25-minute episode; a feature film is about three. Credits are $1.25 each in packs, the first episode is free, and there is no subscription. An episode takes a few minutes; you get an email when it is ready.
