Our Annotation Services

Deep, detailed, and scalable data annotation solutions tailored for AI—from audio to imagery.

Transcription

Transcription Project

Our transcription service converts audio and video into meticulously crafted text. We support all major formats (MP3, WAV, MP4), employ advanced noise‑reduction algorithms, and leverage expert linguists for time‑coded transcripts. Each file undergoes a two‑tier review—initial transcription followed by QA—to guarantee accuracy above 99%, even in multi‑speaker, noisy environments.

Translation

Translation

We deliver translation in over 30 languages using a hybrid approach: neural machine translation followed by human post‑editing. Our linguists specialize in domains like finance, medical, legal, and technical, maintaining custom glossaries and style guides. DTP support preserves your original layout in InDesign, PowerPoint, or HTML, delivering ready‑to‑publish materials without extra formatting.

OCR

OCR (Optical Character Recognition)

Our OCR pipeline digitizes scanned documents and images with up to 99% character accuracy. We pre‑process scans for deskewing and contrast enhancement, then apply script‑specific models supporting Latin, Cyrillic, Arabic, and CJK. Layout detection preserves columns, tables, and images, outputting searchable PDFs, Word docs, or raw text for seamless integration.

Data Collection

Data Collection

We manage end‑to‑end data collection campaigns for your ML needs. From recruiting century‑wide voice contributors to capturing real‑world and synthetic imagery, our secure platform tracks progress in real time. All data is anonymized and compliant with GDPR, ensuring both diversity and privacy in the datasets you receive.

Data Annotation

Data Annotation

Our specialists annotate text, image, audio, and video using custom tools. We handle named-entity recognition, sentiment tagging, bounding boxes, semantic segmentation, speaker turns, and more. Each project follows strict guidelines and multi‑level QA—peer review, expert adjudication, and automated checks—to deliver high-consistency, AI-ready datasets.

Phonetics

Phonetics

We provide expert phonetic transcription with IPA or custom alphabets, capturing phoneme‑level detail, stress, intonation, and dialect nuances. Our linguists annotate prosodic elements and regional accents, delivering data in ELAN, Praat TextGrid, or JSON formats. Triple-check reviews ensure absolute phonetic fidelity for ASR and TTS training.

Image Annotation

Image Annotation

Our computer‑vision team annotates objects, keypoints, and regions using bounding boxes, landmarks, and segmentation masks. We support single-frame and video annotation, ensuring consistency across frames. Quality checks include IoU thresholds and edge-accuracy metrics, guaranteeing precision above 98% for autonomous driving, retail, and medical imaging applications.

Polygon Annotation

Polygon Annotation

For tasks requiring exact shape boundaries—medical scans, aerial maps, product contours—our polygon annotation delivers sub-pixel accuracy. Using tailor‑made polygon tools, annotators trace complex outlines, handle overlaps and holes, and export masks compatible with COCO, Cityscapes, or custom schemas. IoU‑based QA validates annotation fidelity above 97%.
