Spanish Linguist & Fluency and Pronunciation Coach | Localization & QA

Need Spanish that sounds natural, clear, and appropriate for real people? I’m a native Chilean Spanish linguist, pronunciation coach, and Speech-Language Pathologist specializing in linguistic QA, localization, AI language evaluation, and professional Spanish communication. I help companies improve Spanish content for AI systems, digital products, and Latin American audiences. I also coach international professionals who need to communicate more clearly and confidently in Spanish. ### Linguistic services • Spanish proofreading, editing, and content review • Linguistic QA and translation review • Localization for LATAM, neutral, and Chilean Spanish • English-to-Spanish translation and cultural adaptation • Machine translation post-editing (MTPE) • AI and LLM output evaluation • Data annotation and validation • Language-learning content review I evaluate more than grammatical accuracy. I identify language that may be technically correct but still sounds unnatural, unclear, inconsistent, or inappropriate for its intended audience. ### Spanish pronunciation and communication coaching I help international professionals improve their Spanish for real workplace and everyday situations, including • Meetings and professional conversations • Pronunciation, clarity, and intelligibility • Presentations and interviews • Organizing ideas while speaking • Reducing hesitation in spontaneous conversations • Communicating with colleagues and clients in Latin America My coaching is practical and personalized. Instead of relying on generic grammar lessons, I identify the specific issue- pronunciation, fluency, word retrieval, sentence organization, or interaction- and design focused practice around it. ### Relevant experience • Reviewed and processed 2,000+ language segments • Achieved a 100% QA score after project calibration • Worked with LATAM and Chilean Spanish localization requirements • Applied detailed style guides, terminology, and quality criteria • Native Chilean Spanish speaker with fluent English My background in Speech-Language Pathology gives me an additional perspective on how language is processed, produced, and understood. This is especially valuable for conversational AI, voice products, pronunciation content, language-learning applications, and professional communication. You can hire me for linguistic QA, localization, AI language evaluation, content review, or personalized Spanish pronunciation and communication coaching. .
