Labeling Experience

AI Data Specialist (Freelance)

LabelboxAudio

As an AI Data Specialist, I annotated, reviewed, and validated large-scale audio datasets for training AI models. I performed transcription, segmentation, labeling, and comprehensive quality checks with high accuracy. My work included evaluating outputs for correctness and flagging edge cases to enhance dataset usability. • High acceptance rates and consistent performance across repetitive annotation tasks. • Independent execution of tasks using strict platform deadlines. • Focused on guideline compliance and detailed evaluation for ASR and TTS systems. • Contributed to continuous improvement in dataset quality and model training.
