Labeling Experience

Freelance Data Annotation Projects

RemotasksAudioTranscription

I performed audio annotation involving transcription review, speaker tagging, and timestamping for AI model development. I ensured that provided transcripts were accurate and aligned with established standards. Tasks included flagging unclear audio and providing documentation for complex cases. • Labeled audio datasets using Remotasks and Appen. • Verified and corrected transcriptions and timestamps. • Applied speaker segmentation and noise identification. • Identified and escalated edge cases to project leads.
