Freelancer Overview

I am an experienced AI contributor specializing in voice-based data annotation and evaluation tasks. My background includes conducting both structured and unscripted conversations with AI systems, assessing transcription accuracy, and providing detailed feedback to improve speech recognition models. I have a strong command of native-level Newcastle English (Geordie), which enables me to deliver clear, natural speech and evaluate system performance from a linguistic perspective. My skills include data labeling, transcription review, and speech intelligibility assessment, all performed with a high level of attention to detail and confidentiality. I am proficient with web-based AI platforms, audio recording tools, and online communication software, and I excel at working independently in remote environments to meet project deadlines and quality standards. I am eager to contribute to AI training data projects that enhance the accuracy and reliability of language technologies.
