Valentina A.

I’m deeply passionate about language — its sound, its nuance, and its impact — across both human voice and AI-powered speech systems. I specialize in AI Voice & Speech Quality Assurance, localization, and transcreation for global brands and technology-driven teams. With years of experience in linguistic quality, voice performance, and project management, I bring a rare combination of technical precision and creative sensitivity. I understand how language must function — not only creatively, but structurally and acoustically — whether delivered by a human voice or generated by AI. My work is driven by responsibility, consistency, and an exceptional attention to detail. I don’t just review language — I refine it until it sounds natural, culturally accurate, and production-ready. 🔹 AI Voice & Speech QA Text-to-Speech (TTS) evaluation & quality scoring Naturalness, pronunciation & prosody assessment AI voice dataset review & annotation Prompt evaluation & linguistic validation Speech model testing & structured feedback AI training data quality control I help AI voice systems sound more human, more accurate, and more trustworthy. 🔹 Localization & Transcreation Marketing & brand transcreation (ES/EN) Cultural adaptation for global audiences Creative content localization Linguistic QA (LQA) Terminology management & consistency control I ensure your message doesn’t just translate — it resonates. 🔹 Voice Over & Audio Professional Spanish voice over Script adaptation for natural speech flow Audio QA & pronunciation review Tone, clarity & delivery refinement I collaborate with startups, agencies, and global teams who value precision, accountability, and high-quality linguistic execution.
