As a call reviewer at Humanatic, I was responsible for listening to audio recordings and classifying them according to predetermined categories. My main task involved analyzing conversations in English and answering questions about the context and content of each call. I contributed to a quality control process that supports AI systems in understanding and categorizing audio data. • Evaluated and labeled call recordings based on category guidelines. • Ensured consistency and accuracy in labeling for improved machine learning processes. • Used Humanatic's internal labeling software to process assignments. • Collaborated with team members to resolve ambiguous cases.
