What we do
The hard languages, done at production scale
Translia is an ISO 17100 and ISO 18587 certified language data and localization company based in Beijing and Hong Kong, specializing in Asian-language speech data and code-switching audio for AI training. We build training and evaluation data with sourced, vetted native speakers under managed production — the model that matters most for exactly the languages and scenarios general data vendors struggle to source.
Services
Four data lines for model builders

Speech Data Collection

Scripted and spontaneous speech, dual-speaker conversational, and dialectal recordings. Managed speaker sourcing with strict technical specifications — sample rate, channel configuration, recording environment, and speaker demographics — validated per batch.

Code-Switching Audio

Cantonese-English, Mandarin-English, and other mixed-language scenarios — the current frontier of speech AI, where most vendors cannot source natural, native code-switching at scale.

Transcription & Validation

Multi-language transcription and validation QA at production scale, with per-batch turnaround and client-defined guidelines — the quality gate between raw audio and usable training data.

MT & LLM Evaluation

Adequacy, fluency, ranking, and LQA by native evaluators — human judgment on model output, applied consistently and at volume across languages.

Why Translia
Managed production, not crowd labor

One accountable partner

Managed production with a single point of accountability — not anonymous crowdsourcing. Sourced and vetted contributors, strict spec compliance, and per-batch quality confirmation.

Asian variants others can't source

Hong Kong Cantonese, Taiwan Mandarin, Simplified Mandarin, and regional variants — plus Korean, Japanese, Filipino, Turkish and a growing set. The variants that general vendors treat as edge cases are our core.

Active multi-language line

A live production line running across many languages and growing, with a self-serve contributor platform that handles automated dispatch, delivery, and QA tracking.

Consent & provenance

Documented consent per contributor and tracked provenance per batch — auditable data origin and licensing, not open-web scraping.

Certified & controlled

ISO 17100 and ISO 18587 certified, with structured review built into delivery rather than bolted on after complaints.

Company-to-company

We support leading AI platform providers and larger data companies as a subcontracted production partner — a company-to-company engagement model, not a marketplace.

In production
What the line looks like in practice

Code-switching, pilot to scale in weeks

Scaled a Cantonese-English code-switching recording program from pilot to hundreds of scripts within three weeks for a major global AI program — batches accepted with quality confirmed.

Rolling transcription validation

Operating a rolling multi-language transcription validation line across dozens of language variants, delivering weekly batches into a leading AI platform provider's data supply chain.

Client programs are confidential. These describe the shape of the work — managed production, strict specs, quality confirmed per batch — not the parties involved.

Common questions
AI language data,
answered

What languages do you cover for AI data?

Asian languages and their regional variants — Hong Kong Cantonese, Taiwan Mandarin, Simplified Mandarin, and other Chinese variants — alongside Korean, Japanese, Filipino, Turkish, and a growing set. We also handle code-switching such as Cantonese-English and Mandarin-English.

How do you ensure data provenance and consent?

Every contributor works under documented consent, with provenance tracked per contributor and per batch. As an ISO 17100 and ISO 18587 certified company running managed production, data origin, licensing, and processing are auditable — not sourced anonymously from open crowdsourcing.

Can you handle strict technical specifications?

Yes. Speech collection follows strict specs — sample rate, channel configuration, recording environment, speaker demographics, and script design — validated per batch before delivery. Transcription and evaluation follow client-defined guidelines with QA at production scale.

Do you work as a subcontractor to larger data companies?

Yes — we support leading AI platform providers and larger data companies as a company-to-company engagement, delivering managed production capacity in Asian languages and code-switching audio that general vendors cannot easily source.

How is this different from crowdsourced data platforms?

We run managed production with one accountable partner, not anonymous crowd labor — vetted native speakers, strict spec compliance, documented consent and provenance, and per-batch quality confirmation. That matters most for the hard cases: code-switching and low-resource Asian variants.
