Animated promo, 23 seconds, music only, no narration. On screen: built in Ukrainian; AI speaks English; zero construction datasets. Step 1: speech is recorded on site. Step 2: speech and DBN building codes are cut into segments. Step 3: NER annotation in three passes with nine labels, 2,492 segments. Step 4: export as JSONL for AI. Target text corpus: 100M+ tokens. Building Ukrainian construction language for AI. BUDOVA, budov.org, supported by Microsoft AI for Good Lab.

Initiative

LINGUA Open Call

A Microsoft AI for Good Lab initiative under EU Digital Unlock, supporting digital inclusion for low-resource European languages. The open call selected 11 projects covering 16 languages and dialects across 10 countries.

Microsoft

Up to $50,000 Funding

Grant support for language data collection for low-resource European languages.

Azure Compute Resources

Cloud computing credits for up to 2 years for data processing and validation.

Technical Support

Research collaboration with Microsoft AI for Good Lab.

Open Models

Integration with Apertus, EuroLLM, SmolLM3 and other multilingual models.

Challenge

Why This Is Critical

Despite 30–46 million speakers, Ukrainian remains critically underrepresented in AI technologies — especially in specialized domains.

<0.6%
of web content in Ukrainian

Digital Exclusion

No technical language datasets, speech recognition systems for construction sites, or AI tools supporting Ukrainian building codes.

3
dialect groups, 15+ subdialects

Dialect Diversity

Northern, Southwestern (Volhynian, Podolian, Upper Dniester, Upper Sian, Pokuttia–Bukovyna, Hutsul, Boyko, Transcarpathian, Lemko), and Southeastern dialect groups remain undocumented in technical contexts — AI systems risk failure for non-standard speakers.

15–25%
performance gap

Morphological Complexity

Cyrillic script, 7 cases, 3 genders, moveable stress — unique tokenization challenges with a performance gap vs. English.

What We Build

Open Resources for Construction

Our goal: the first comprehensive Ukrainian technical language dataset with dialectal coverage across all major regions of Ukraine.

Speech Dataset

Target: 100+ hours of annotated construction speech with transcriptions, covering Northern, Southwestern, and Southeastern Ukrainian dialects. Read-aloud collection opened in October 2026.

>0.70Expert kappa · target

Text Corpus

Target: 100M+ tokens of raw construction text — building codes, legislation, estimating norms, open-access journals. The NER-annotated subset already holds 2,927 segments from nine building codes (ДБН).

Roadmap

24 Months, 5 Phases

A phased plan with quarterly releases for community feedback. The first public data release is v1.0 (Q4 2026).

01 / 05Phase 1

Infrastructure & Preparation

Months 1–3 · Jan – Mar 2026

Infrastructure setup, GDPR protocols, participant recruitment.

02 / 05Phase 2

Data Collection

Months 4–15 · Apr 2026 – Mar 2027

Plan: 25 h of speech + 25M tokens per quarter toward the 100+ h and 100M+ token targets. Status, October 2026: 9 building codes annotated (2,927 segments); read-aloud speech collection has started.

03 / 05Phase 3

Annotation & Validation

Months 6–18 · Parallel with collection

Two-stage validation: crowdsourced transcription, then expert review. Target: human expert agreement κ > 0.70; text annotation passes have a separate agreement threshold, κ ≥ 0.8.

04 / 05Phase 4

Baseline Model Development

Months 12–21 · Dec 2026 – Sep 2027

Training ASR and NER models on collected data. Target: WER <25% for construction terminology.

05 / 05Phase 5

Release & Transfer

Months 21–24 · Sep – Dec 2027

Final dataset release on Hugging Face and Zenodo with DOIs. Documentation, sustainability transition.
