Generate English subtitles for your Hausa videos

Tone in the Hausa audio

Hausa uses tone to distinguish words that are otherwise identical, so recognition depends on pitch as well as on the sounds themselves. Background music is unusually costly here — it competes with exactly the cue the recogniser needs.

Where tone was misheard, the English translation follows the wrong word rather than producing obvious nonsense, so errors read as plausible. A pass over the transcript before translating is worth more on Hausa than on most languages.

How Hausa audio becomes English subtitles

Audio in Hausa (Hausa) is transcribed first, then translated into English (English). Because the translation runs on the transcript rather than on the audio, the English subtitle file keeps the timings of the original Hausa speech — each line appears at the moment it was actually said.

Why translate Hausa video into English

Hausa is spoken principally in northern Nigeria, Niger and across the Sahel; English in worldwide. A English subtitle track is what lets one recording reach both audiences without re-recording, re-editing or dubbing it.

Because subtitles are a separate file rather than part of the picture, you can attach several language tracks to the same video and let viewers pick.

About the Hausa audio

Hausa is tonal, and its standard Latin orthography uses hooked letters — ɓ, ɗ and ƙ — for sounds English has no equivalent of. Those characters are part of the word, so check that whatever plays your subtitle file renders them rather than substituting plain b, d and k. Hausa is also written in the Arabic-derived Ajami script in some contexts; transcription here produces the Latin form.

About the English subtitles

English has a wider spread of accents than any other language here, and the gap between spelling and pronunciation means recognition leans on context rather than sound alone. Names and technical terms are where errors concentrate, because those are exactly the words context cannot predict.

What to check before publishing

• Names and places, which translation handles less reliably than ordinary prose.
• Idiom — a phrase that is natural in Hausa may need loosening to read well in English.
• Timing on fast exchanges, where two speakers overlap.
