Freelancer Overview

I am an experienced AI Data Annotator specializing in speech, audio, image, website data, with a focus on refining AI-generated transcriptions for Indonesian conversational speech. My work involves audio segmentation, speaker labeling, and ensuring transcription quality through detailed error analysis and quality assurance. I have successfully contributed to projects that improve speech recognition training data by evaluating segmentation, identifying recurring error patterns, and providing actionable recommendations. I am skilled in using tools such as Audacity for waveform analysis, Google Speech-to-Text for baseline transcriptions, Excel for error tracking, and Notion for documentation and quality analysis. My background in legal administration and data entry further strengthens my attention to detail and organizational skills, while my experience with digital tools supports efficient and accurate annotation workflows.
