"booth interpreting"
Simultaneous interpreting performed from a soundproofed booth where the interpreter listens via headphones and speaks into a microphone.
"The conference centre provided four booths for booth interpreting in English, French, Spanish, and German."
"relay interpreting"
A technique where the output of one interpreter is used as the input source by another, allowing rare language combinations to be covered indirectly.

Frequently Asked Questions
Why is English important for translation and interpreting professionals?
English is the dominant working language of the global translation industry, international conferences, and major CAT tool documentation. Whether you translate into English or work in multilingual environments, strong professional English helps you communicate with clients, read industry standards, and navigate tools and resources that are largely published in English.
What vocabulary do I need for translation and interpreting in English?
You need terminology across six key areas: translation theory (source text, equivalence, skopos), the translation process (CAT tools, translation memory, revision), interpreting modes (simultaneous, consecutive, relay), localisation (transcreation, pseudo-localisation, MT), specialised fields (legal, medical, certified translation), and quality and ethics (ISO 17100, confidentiality, QA).
What is the difference between translation and interpreting?
Translation involves converting written text from one language into another, typically with time to research, draft, and revise. Interpreting involves rendering spoken communication orally, in real time or with short pauses. The two professions require overlapping but distinct skill sets — interpreters, for example, need exceptional short-term memory and stress tolerance that written translators can develop more gradually.
How do CAT tools help translators?
Computer-Assisted Translation (CAT) tools store previously translated segments in a translation memory, automatically suggesting matches when similar text appears again. This ensures consistency across large documents, speeds up delivery, and reduces costs on repetitive content. Most professional translation agencies and clients require translators to use CAT tools for anything beyond short documents.
Can I learn professional English for translation through videos and authentic content?
Absolutely — and it is one of the most effective approaches. Watching conference recordings, industry webinars, and interviews with professional translators and interpreters exposes you to authentic pronunciation and the vocabulary used in real professional discussions. Comprehensible input at your level builds fluency far more effectively than memorising word lists alone.
The fastest way to absorb professional English is through comprehensible input — real content at your level.
