Diego D.

Hi! 👋 I help teams improve AI and multilingual content through careful evaluation, annotation, and language work. I’m a native Spanish and Catalan speaker with professional proficiency in English, and I’ve been freelancing for more than five years. I enjoy work that calls for a sharp ear, attention to detail, and clear feedback—whether I’m reviewing an AI response, checking a translation, or listening closely to a voice recording. How I can help: AI training and data annotation: Evaluate AI-generated responses, compare outputs, categorize data, and moderate content. I’ve contributed to projects with Data Annotation, TELUS, Welocalize, RWS, Centific, Appen, and OneForma. Speech and dubbing evaluation: Review AI-generated voices and dubbed audio or video for translation accuracy, pronunciation, naturalness, rhythm, voice similarity, audio quality, lip-sync, and speaker attribution. 🎧 Translation and language support: Translate and localize between English, Spanish, and Catalan, as well as proofread and transcribe Spanish and Catalan audio. My translation work has included RunRepeat, VEED, FaceYoga, CasinoRey, and Convertbinary. 🌍 I’ve also worked on social media content moderation, app and product testing, and voice data entry. My academic background includes a Master’s degree in Sustainable Tourism and studies in Translation and Technologies at the Universitat Oberta de Catalunya (UOC). I’m easy to work with, communicate clearly, and take project guidelines and deadlines seriously. If you need a careful multilingual reviewer or evaluator, I’d be glad to hear about your project. ✨
