Hand-picked, degree-qualified linguists with 11+ years of professional translation experience. Not crowd workers — domain specialists delivering the precision data that trains the world's most ambitious AI models.
AI is only as good as the data it's trained on. Every AvantLingua team member is a rigorously vetted native Vietnamese speaker with a professional linguistics background — not a crowdsourced gig worker. Your dedicated team learns your terminology and maintains consistency across every deliverable.
BA or MA in Linguistics, Translation Studies, or a related field is the minimum. We don't compromise on academic foundations.
C2-level (Mastery) certification ensures every linguist operates at near-native bilingual fluency.
Over a decade of professional translation across legal, technical, and business domains. Our team understands context, not just words.
Every deliverable passes through multi-tier linguist review. No automated shortcuts. 97%+ quality threshold on every project, verified by the experts who understand the language.
High-quality ranking, preference labeling, and logic-checking for LLM outputs. Our linguists evaluate nuance, cultural context, and factual accuracy that automated pipelines miss.
Precision ASR/TTS data for Vietnamese speech models. Native speakers capture tonal distinctions, regional dialects, and conversational nuance with clinical accuracy.
AvantLingua began as a freelance translation practice in 2015, serving international clients across legal, technical, and business domains. Over 11+ years, we built a reputation for precision that global firms stake their projects on.
Today, we bring that same rigor to AI. Our team doesn't just annotate data — they understand language at the structural level. When your model needs to distinguish between a polite Vietnamese request and a direct command, or when tonal markers change meaning entirely, our linguists catch what algorithms can't.
We're not a staffing agency. We're a curated team of domain-specialist linguists who happen to be exactly what AI companies need. Native-speaking experts, not crowd workers — assigned to your project, learning your terminology, maintaining consistency at scale.
