Ukrainian TTS datasets
Everyday Ukrainian speech mixes Ukrainian and Russian in proportions that vary from speaker to speaker, a mix known as Surzhyk. In a synthesis project this becomes a script decision rather than a transcription one: the text is written in the register the voice is meant to speak, and the speaker is chosen for that register rather than for whatever they happen to speak at home.
What TTS work in Ukrainian requires
Speaker consistency across sessions
A voice recorded over several days drifts in pitch and pacing. If the target is one synthetic voice, either record in fewer, longer sessions or plan to re-record segments that fall outside tolerance.
Text the speaker can read fluently
A speaker reading unfamiliar script produces disfluencies that end up baked into the synthetic voice. Script selection matters as much as recording quality.
Phonetic coverage, not just volume
A long recording can still miss phonemes that are rare in running text. Coverage has to be checked against the language's inventory, not against word count.
The mistake that costs the most
The most common mistake is buying many hours from many speakers when the goal needed a few hours from one speaker, recorded properly.
The language-specific factor
Everyday Ukrainian speech is a mix of Ukrainian and Russian (Surzhyk), in proportions that vary from speaker to speaker. On top of that, many people searching this term are language learners. A dataset page has to target the dataset intent only and not drift toward learning demand.
