I reviewed AI-generated responses and ranked them according to naturalness, truthfulness, and instruction adherence. I evaluated generated images by AI for alignment with user prompts and ranked them for performance. I ensured feedback for model improvement was consistent and detailed. • Provided structured and ranked feedback on text and image outputs. • Supported RLHF (Reinforcement Learning from Human Feedback) workflows. • Applied quality control procedures for data annotation tasks. • Used various annotation platforms, including Outlier and Scale AI.

AppenAudioTranscription
I transcribed multi-speaker audio recordings such as podcasts, interviews, and sports commentaries into clear, time-stamped text. I performed speaker separation, accurate punctuation, and reviewed transcriptions for quality. I also carried out audio labelling and voice identification for segmenting tone, emotion, and speakers. • Annotated audio for proper classification and speaker identification. • Processed complex multi-speaker environments, including sports events. • Tagged audio segments for emotion and event type. • Adhered to detailed annotation rubrics and submission protocols.
