The project involved background noise, multiple speakers, dialectal variation, and mandatory segmentation rules.

The problem to solve

The buyer needed language coverage to expand while rolling batches kept moving.

Rare-language transcription pools had to be built without letting the active program stall.

What MoniSa changed

MoniSa created a rare-language workforce path using regional communities, universities, diaspora networks, and pilot batches before scaling.

  • Pilot before scale

    Each rare language moved through a pilot track before joining the live production flow.

  • Localized training

    Training materials were adapted for linguists who needed more context before production.

  • Three review layers

    Transcription, reviewer checks, and QA audit kept the rolling cadence measurable.

Results

Measured outcomes from this engagement.

The program delivered 10,000+ hours across 140+ languages, with quality reviewed under the engagement rules.

What supported the result

Why the fit was real

The work needed rare-language workforce creation and a rolling QA system at the same time.

What decided the result

New languages entered through pilots instead of being dropped directly into live production.

What buyers can reuse

  • Rolling speech data programs need workforce creation before task assignment.
  • Rare-language expansion stayed controlled because every language entered through a pilot path.
  • Quality language is scoped to this engagement, not stated as a company-wide guarantee.

AI data servicesPhased audio collection kept training ingestion moving.

Compressed audio collection

The challenge. An AI data buyer needed multilingual audio fast without waiting for a single final handoff.

What we did. MoniSa split contributors by language, controlled scripts, and delivered phased batches.

The result. The buyer could begin using early datasets while collection continued in parallel.

Device voice data collection

Problem. A voice AI team needed speaker diversity across a broad multilingual collection.

Action. MoniSa recruited by language, accent, and demographic fit, then checked every recording.

Result. The buyer received voice data designed for accent-aware device recognition.

Maithili ASR transcription

Problem. A speech AI buyer needed Maithili conversation captured with training-ready structure.

Action. MoniSa paired native linguists with synchronized transcription and JSON export workflow.

Result. The buyer received structured ASR data instead of a flat transcript cleanup burden.

Where should similar work go next?

Use AI data services for the delivery model, AI data annotation vendor guide for buyer-side evaluation, and the contact page for a scoped brief.

What happens if you cannot staff one of my language pairs?

For the proposed project, ask for pair-by-pair availability or a recruitment window in writing before agreeing a date. Define qualification and pilot approval for any new contributor before live work. A coverage claim should be checkable before the scope is signed.
