How the Annotation Process Works
The same four-stage pipeline applies to every Greensboro client — with dedicated project management and full QA transparency at every step.
Scope &
specification
Share your use case, data modality, label taxonomy, language targets, and quality requirements. We produce a detailed specification — annotation schema, edge-case decision rules, and QA rubrics — within one business day.
Match domain-expert annotators
We assign annotators matched to your domain — not just your data type. Legal text goes to legal professionals; medical data to clinicians; technical audio to domain engineers. Annotators are calibrated on your task before production begins.
Annotate with multi-stage QA
Every batch passes automated consistency validation, inter-annotator agreement (IAA) measurement on calibration samples, and senior reviewer sign-off. Batches below QA threshold are re-annotated before delivery.
Deliver with full QA report
Receive your dataset in your preferred format — COCO JSON, CoNLL, TextGrid, MOT CSV, or custom schema — alongside a full QA report with per-class accuracy, IAA scores, rejection rates, and revision log. Free revisions within scope.

Audio & speech annotation — speech transcription (verbatim and normalized), speaker diarization, sound event detection, phoneme and word alignment, emotion tagging, voice activity detection, and audio quality assessment.
How quickly can Synnth start and deliver a project for a Greensboro AI team?
After an initial scoping discussion, we can begin a pilot batch within 24–48 hours. Pilot batches are delivered within 48–72 hours at full production QA standards. There is no location-based delay for Greensboro clients. For qualifying projects, Synnth offers a free pilot batch so teams can validate annotation quality before committing to full-scale production volumes.
How does Synnth ensure annotation quality?
Synnth applies a multi-stage QA pipeline to every annotation project: (1) Automated validation — geometry checks for image and video tasks, format validation for text, acoustic quality screening for audio; (2) Inter-annotator agreement (IAA) — measured on calibration samples using Cohen’s kappa (two annotators) or Fleiss’ kappa (three or more), targeting above 0.80 on standard tasks; (3) Senior reviewer sign-off — every batch reviewed and approved by a senior annotator before delivery. Synnth maintains a 98.5% average QA accuracy across delivered projects, and every delivery includes a full QA report with per-class accuracy, IAA scores, and revision logs.
Can Synnth handle HIPAA-compliant annotation for Greensboro healthcare AI?
Yes. Healthcare annotation projects — medical image labeling, clinical note NLP, EHR classification — are handled under HIPAA-ready protocols: access-controlled annotation environments, Business Associate Agreements (BAAs) where required, annotators with relevant clinical training, full audit trails, and strict NDA coverage. This is available to Greensboro hospital systems, healthtech startups, pharma companies, and clinical research institutions.

Synnth supports annotation in 40+ languages with native-speaker annotators for each — covering all major world languages as well as regional and low-resource languages. For Greensboro-focused AI products, this includes Spanish, Mandarin, Cantonese, Hindi, Bengali, Arabic, Russian, Korean, Polish, Haitian Creole, Tagalog, and many more. All annotation is performed by native speakers — not translators — to ensure linguistic accuracy and cultural nuance.
