Data Annotator
I annotated and labeled large-scale datasets for text-based AI projects according to specific linguistic and contextual guidelines. My responsibilities included transcribing audio in English, Hindi, and Bengali with a focus on accuracy, and performing multilingual data validation to optimize NLP model outcomes. Additionally, I reviewed and corrected transcription outputs to maintain quality standards and addressed edge-case language scenarios. • Processed over 1,500 data points weekly, ensuring productivity targets were consistently met. • Ensured precise grammar, punctuation, timestamps, and formatting in all transcripts. • Handled mixed-language (code-switching) audio and validated data for NLP accuracy improvements. • Maintained high-quality benchmarks and reduced error rates in labeled datasets.
