Expert Machine Translation for Any Data Type
We offer high-quality machine translation across every modality—audio, image, video, text, and multimodal—ensuring diversity, compliance, and scalability for your AI training needs.

Audio
Enable high‑quality speech translation and spoken content experiences:
- Speech Translation (ASR → MT → TTS): Chain ASR with translation and optional TTS for multilingual audio experiences. (Evaluation and post‑editing steps mirror our MTPE and QA methods).
- Subtitle & Transcript Localization: Translate time‑aligned transcripts while preserving speaker intent, tone, and style.
- Audio QA & Review: In‑context checks for terminology, timing, and listener comprehension, with multi‑checkpoint sign‑off.
Image
Localize text embedded in visual assets and UI flows:
- OCR + Translation: Extract, translate, and review text from screenshots, documents, and product imagery using human QA.
- UI/UX String Localization: Validate tone, truncation, and context within screenshots or design mocks; prevent duplicates via reference translation.
- Visual Context Evaluation: In‑context assessment to ensure translations match imagery, use case, and audience.
Video
Scale multilingual video with accuracy, fluency, and timing fidelity:
- Caption & Subtitle Translation: Translate and normalize subtitles; reviewers verify timing, reading speed, and cultural fit.
- Side‑by‑Side Quality Review: Compare candidate translations for accuracy and fluency on representative clips.
- In‑Context Evaluation: Judge perceived quality within scene context and narrative flow for realistic user impact.
Text
Core services for training, fine‑tuning, and validating MT systems:
- Human Translation (100+ language pairs): Native‑target linguists deliver faithful translations with style and register preserved; layered quality checkpoints included.
- Machine Translation Post‑Editing (MTPE): Professional editors correct machine output for accuracy, fluency, and terminology; Neevo demo available.
- Paraphrasing / Reference Translation: Produce paraphrases to diversify datasets; prevent duplicates through reference translation; Neevo demo available.
- Translation Evaluation: Side‑by‑side comparisons, accuracy/fluency scoring, and in‑context quality evaluation with reporting dashboards and examples.
Multimodal
Support products that mix text, audio, and visuals:
- Image‑Text & Audio‑Text Alignment: Verify that translations align with visual or spoken context for clarity and intent preservation.
- Cross‑Channel Consistency: Ensure terminology and style are consistent across UI strings, help with content, subtitles, and voiceover scripts.
- Scenario‑Based Evaluation: Run in‑context reviews that reflect real user journeys (e.g., onboarding flows, support walkthroughs).
