Sigma Meaning
Teach your AI to speak human
Language is more than words. It’s intent, nuance, culture, and emotion. Sigma Meaning ensures your generative AI doesn’t just translate or transcribe — it understands. Our human annotators embed context, dialect, and cultural relevance to help your model resonate with users across regions, languages, and lived experiences.
WHAT WE DELIVER
AI that understands what people actually mean
Sigma’s experts bring deep linguistic, cultural, and contextual knowledge to every annotation task — equipping your AI to interpret and generate communication that feels real, respectful, and insightful.
Core workflows include:
- Multilingual & dialect annotation: Support for 700+ languages and regional dialects, reflecting real-world usage.
- Short & long-form transcription: Capture spoken content with 99%+ accuracy, including accents, disfluencies, and slang.
- Translation & localization: Go beyond literal meaning to culturally appropriate phrasing and tone.
- Contextual enrichment: Add annotations for intent, tone, and speaker context to help AI generate meaning-rich outputs.
- Cultural calibration: Prevent offensive, tone-deaf, or irrelevant outputs by embedding cultural norms.
Example workflow
+ The artifact
An AI‑generated audio clip pronounces the Mandarin phrase māma mà mǎ (妈妈骂马) with identical tone contours for each syllable.
+ The task
Annotators review the waveform and phonetic transcription, then mark the correct tone for each syllable (high level, rising, falling‑rising, or falling) so the meaning is accurately conveyed:
- māma (high level) = mother
- mà (falling) = scold
- mǎ (falling‑rising) = horse
Annotators also flag if the model over‑emphasizes or flattens a tone.
+ The impact
In tonal languages like Chinese, pitch contours directly affect meaning. Without proper annotation of tone and emphasis, the AI risks producing speech that sounds fluent but conveys the wrong message — e.g., “mother scolds horse” might be misheard as unrelated nonsense.
HOW WE DO IT
Real humans, real context, real accuracy
Meaning is where machines still fall short — and where Sigma excels. Our annotators:
- Transcribe and translate with deep fluency and regional familiarity
- Understand evolving slang, idioms, humor, and subtext
- Annotate speech and text with emotional and situational context
- Help models navigate multilingual environments with clarity and sensitivity
Whether your use case is healthcare, customer service, or global search, Sigma provides the human insight required for nuanced AI interaction.
WHY IT MATTERS
Because misunderstanding is expensive
Misinterpreted intent, clumsy tone, or cultural insensitivity can cost you users — or worse, trigger reputational harm.
With Sigma Meaning, you ensure:
- Culturally competent and emotionally intelligent AI
- Superior performance in multilingual and multi-market deployments
- Greater clarity, empathy, and engagement in user interactions
- Fewer misunderstandings — and better outcomes
