Spanish (Spain) Voice | AI Data QA | Localization & Proofreading

I’m a native Spanish speaker from Spain with paid experience in **European Spanish voice recording, AI data collection and validation, localization review, proofreading, and linguistic QA**. I help clients make Spanish content sound natural, accurate, and genuinely written for audiences in Spain, whether the project involves voice, AI-generated content, translated text, datasets, or digital products. ### What I can help you with • **Spanish (Spain) voice recording** for AI datasets, conversational projects, narration, TTS, characters, and voice samples • **Localization and naturalness review** for translated or AI-generated Spanish • **Proofreading and linguistic QA**, including grammar, tone, consistency, terminology, and Spain-specific usage • **AI data collection, validation, annotation, and quality review** • **TTS and audio evaluation**, including pronunciation, naturalness, rhythm, and recording quality • **Website, app, UI, and digital content review** for Spanish-speaking users in Spain • **Administrative and document research in Spain** using official sources and structured workflows I have completed paid projects involving Spanish validation, conversational audio, voice recording, audio review, machine-translated text editing, cultural review, data collection, and AI training data. For voice projects, I record from my home setup using a **PreSonus M7 XLR microphone, PreSonus AudioBox iTwo interface, and Audacity**, with clean WAV delivery available. I’m detail-oriented, comfortable following complex guidelines, and careful not to “correct” text unnecessarily when the original wording already works. If your project needs **natural European Spanish, reliable quality control, and clear communication**, I’d be happy to help.
