Machine Translation Post-Editing (MTPE) – English to Spanish
While machine translation has come a long way, “raw” AI output often results in a robotic tone or technical errors that simply don’t work for SEO or conversion. As a freelance translator and proofreader since 1998, I specialise in bridging the gap between technology and language. I ensure your machine-generated content is not only accurate, but also culturally relevant and technically sound. I offer the ideal balance: the speed and cost advantage of AI-driven translation combined with the precision and nuance of over 20 years of human expertise.
I am Roger Garcia, a professional translator and post-editor with over 20 years of experience in the technology industry. I transform machine-generated drafts into high-quality, professional Spanish content that resonates with your target audience.
I’ve collaborated with many IT companies to fine-tune and perform QA on their AI-translated content. From high-traffic websites to marketing collaterals, I specialize in ensuring that complex technical assets sound natural and persuasive for the Spanish market. In these cases, simply correcting grammar is never enough; I apply localization techniques to adapt the technical essence of the copy, providing a high-impact result comparable to professional transcreation but at a much lower cost than traditional translation.

Frequently asked questions (FAQs)
What is the difference between traditional translation and MTPE?
Traditional translation starts from a blank page, with the linguist crafting every sentence from the source. MTPE (Machine Translation Post-Editing) uses an AI-generated draft as a base, which a professional linguist then corrects and refines. MTPE is significantly faster and more cost-effective, making it ideal for high-volume technical content where maintaining a professional finish is essential.
Will Google penalize my site for using AI-translated content?
No. Search engines like Google do not penalize content simply because it was generated by AI or machine translation. What they do penalize is low-quality, unhelpful content. My post-editing process ensures that the result is high-quality, satisfies the user’s search intent, and meets all SEO requirements. Furthermore, I optimize the text for LLMs (Large Language Models), ensuring your content is clear and well-structured for AI-driven search and discovery.
Will the final quality be the same as a traditional translation?
By definition, MTPE is designed for efficiency. While it is logically not possible to offer the same level of deep creativity as a traditional translation due to time and budget constraints, the result is perfectly suited for the vast majority of business and technical needs. I ensure the output is accurate, fluent, and technically sound, providing a high-quality professional result that meets industry standards.
How much can I save by choosing MTPE over traditional translation?
MTPE is highly cost-effective. By leveraging AI speed and my specialized human review, I can offer rates that are usually 40% to 50% lower than traditional translation. It is the perfect solution for balancing tight budgets with the need for professional, market-ready Spanish content.
Is MTPE suitable for creative marketing content?
MTPE is ideal for technical documentation, websites, and informative content. For high-impact branding or very creative copy, Transcreation is still the gold standard. However, for most marketing collaterals, my «fine-tuning» approach provides a natural, persuasive flow that works effectively for the Spanish market at a fraction of the cost.
Which CAT tools and MT engines do you work with?
I am proficient in all major industry tools, including Phrase (Memsource), memoQ, Trados, XTM, and Lokalise. I can work with output from any engine (DeepL, Google Cloud, or custom-trained models) and integrate directly into your existing localization pipeline.
What is your typical turnaround time for MTPE?
Efficiency is one of the main advantages of this service. I can comfortably process up to 2,000 words per day with full post-editing. For urgent requests or large-scale product launches, I can also offer weekend availability to meet your strict deadlines.
