English expertise for international communication
Personalized coaching, translation and proofreading for professionals and organizations in Switzerland

Hi, I'm David
I love diving into language. Do you?You work hard and your ideas deserve to be heard — clearly, confidently, globally.A long time ago, I became fascinated by the way language connects us with ideas, cultures, and people. My dream was to expand my horizons. But in a classroom, I felt stuck and isolated.Language was more than what I studied. Language was something I experienced.Today, I help professionals and organizations who need precise, natural English to communicate internationally.English with David is more than a language service. It is a reliable working relationship.

Do you use AI and machine translation?
With the incredible boom of AI tools available today, it's no surprise that people are using technology for translation.I use professional language technology like NMT (machine translation), LLM (large language models) and termbases.But this is nothing newTranslators have long been using computers to aid with translation. RBMT (rule-based machine translation) started in the 1950s. As computing capacity increased in the 1990s, SMT (statistical) became possible, which was better.In 2016, NMT became available. The most famous NMT tools now are Google Translate and DeepL.For a computer, NMT is impressively fluent, but it still makes mistakes. The biggest problem is that the text which NMT produces is essentially devoid of meaning. The machine doesn’t understand and therefore, it mistranslates ambiguous terms, misinterprets culturally loaded language, and drops important nuances.LLMs are a major stepLLM stands for large language model. It's what ChatGPT and co. use, and it is very impressive. But LLMs still can't manipulate meaning and can't make decisions the way humans can. LLMs draw on statistical patterns of form and co-occurrence to do translation — just like NMT.While NMTs and LLMs can't translate meaning like humans can, they do offer impressive advantages to translators.A tool is only as good as the hands that hold itThat's why I use them every day to ensure fast and precise translation for my clients. But a tool is only as good as the hands that hold it.I review every text critically and make final decisions based on my understanding of your organization, audience or intention.Technology supports the process. Human judgement determines the result.
