Freelancer Overview

I am a studio voice actor with over six years of experience producing high-quality US English recordings for a wide range of projects, including e-learning, audiobooks, and interactive content. My work frequently involves delivering large volumes of structured, script-driven audio with precise adherence to pronunciation guides, pacing, and tonal consistency—skills essential for creating reliable speech datasets for AI training and evaluation. I operate from a professional home studio, where I handle all aspects of audio editing, file formatting, labeling, and quality control to ensure every WAV file meets strict technical and dataset requirements. My attention to detail, ability to follow complex instructions, and commitment to accuracy make me well-suited for roles in data labeling and annotation, especially in natural language processing and speech technology domains.
