Freelancer Overview

I am a highly experienced AI Data Trainer and Linguistic Annotator specializing in the Japanese and English language areas of data labeling, transcription, and evaluation for large AI and LLM training projects. I have extensive experience in the areas of audio transcription, text evaluation, social media evaluation, and multimodal data annotation. I focus on the production of high-quality and accurate datasets that assist in improving model performance, linguistic accuracy, and cultural relevance. My specialties include Japanese mixed-script transcription (kanji, kana, and romaji) audio segmentation, speaker identification, and text normalization. I have worked on a number of projects in AI development including areas of data labeling, content QA, and model evaluation, ensuring both consistency in the standards of annotations, and also ethical considerations in the handling of datasets. In addition to my transcription skills, I also have familiarity with evaluations of promptness, generative AI output, and linguistic quality assessment in LLM fine-tuning. Bridging the gap between human communication and AI understanding as a bilingual with strong attention to detail and a love of language technology is my overarching goal. I am passionate about assisting AI systems in learning to understand authentic and nuanced natural speech and text in Japanese language contexts.
