Choosing the mode before choosing the interpreter

Mode determines cost, staffing and room setup far more than language pair does. Consecutive interpreting, where the speaker pauses and the interpreter renders each segment, roughly doubles the elapsed time but needs no equipment and suits depositions, notarial signings and small negotiations. Simultaneous interpreting runs in real time from a booth or with a portable system and requires two interpreters per language pair rotating every twenty to thirty minutes, because sustained simultaneous work degrades measurably after that.

Whispered interpreting, or chuchotage, serves one or two listeners in a room otherwise proceeding in Thai. Liaison interpreting suits site visits and factory walkthroughs where the participants move. Booking the wrong mode is the most expensive error in this service: a conference booked as consecutive silently doubles its own schedule.

Settings we work in and what each demands

SettingUsual modeSpecific demand
Notarial signing and power of attorneyConsecutiveThe interpreter's identity is recorded in the certification; neutrality is the point
Court and arbitration hearingConsecutive, sometimes whisperedRegister must be preserved; interpreters do not summarise or soften
Amphur marriage registrationConsecutiveRegistrars require the interpreter to confirm the parties understood the declarations
Board meetings and due diligenceSimultaneous or whisperedTerminology sheet agreed in advance; confidentiality undertaking signed
Medical consultationConsecutiveClinical terms rendered literally, with clarification requested rather than guessed
Factory audit and site inspectionLiaisonMobile, safety-briefed, with technical vocabulary prepared from the audit scope

Preparation that decides quality

  1. Brief and materials: Agendas, prior minutes, contracts and slide decks sent ahead let the interpreter build a glossary. Interpreters given nothing in advance render accurately but slowly, and slowness is what participants perceive as poor quality.
  2. Terminology sheet: Party names, product names, statutory references and internal acronyms are fixed in writing before the session, so the same Thai term is not rendered three ways in one meeting.
  3. Room and audio check: For simultaneous work, receivers, booth or portable transmitter and a clean speaker feed are tested before participants arrive; interpreting from a room microphone at the back is the leading cause of complaint.
  4. Roles and turn-taking: The chair is briefed to pause for consecutive segments and to speak to the participants rather than to the interpreter.
  5. Confidentiality: A non-disclosure undertaking is signed before materials are released, which is standard for due diligence and litigation work.

Where interpreting ends and translation begins

An interpreter renders speech; a translator renders documents. Where a signing meeting produces a text that must be filed, the written version is a separate certified translation, and the certification attaches to the translator who prepared it. Asking the interpreter present to sign an on-the-spot rendering of a contract confuses the two roles and produces a document most registrars will not accept.

Common mistakes and how we avoid them

Booking one interpreter for a full day of simultaneous work
Staff two per language pair with rotation; single-interpreter simultaneous degrades within the first hour.
Withholding materials for confidentiality reasons
Release under an NDA; preparation is what makes accurate rendering possible at speed.
Using a bilingual employee for a hearing
Neutrality matters as much as fluency; an employee with an interest in the outcome is challengeable.
No audio plan for a hybrid meeting
Provide a direct platform feed; interpreting remote participants through a room speaker loses intelligibility.

More questions we are asked

How far in advance should I book?
For conference simultaneous work, two to three weeks secures a pair with the right subject background. Consecutive appointments can often be arranged within days.
Do you provide equipment?
Yes, portable systems for small groups and booth setups for conferences, arranged with the venue's technical staff.
Can the interpreter also certify the translation?
Only if separately qualified for that document type; the roles and the certifications are distinct.
Which languages do you cover?
Thai paired with major European and Asian languages; rarer pairs are arranged with lead time and confirmed before booking.
How is time charged?
By half-day and full-day blocks with defined overtime, because interpreter availability is committed in blocks rather than by the minute.
Can interpreting be provided remotely?
Yes, over the client's platform, provided a clean audio feed and a rehearsal are arranged in advance.

Frequently asked questions

When is an interpreter legally required in Thailand?
An interpreter is required whenever a person who does not understand Thai takes part in an official act — district-office marriage registration, police investigations, court hearings, land office transactions and certain immigration interviews. In criminal proceedings the Criminal Procedure Code guarantees interpretation, and courts keep their own interpreter lists.
What is the difference between consecutive and simultaneous interpreting?
Consecutive interpreting alternates between speaker and interpreter and suits meetings, interviews and district-office appointments, while simultaneous interpreting is delivered in real time from a booth or headset and suits conferences and long hearings. Simultaneous work requires two interpreters rotating every 20–30 minutes because sustained concentration beyond that degrades accuracy.
How far ahead should an interpreter be booked?
Book English, Chinese and Japanese interpreters at least two to three working days ahead, and rare languages such as Hebrew, Hungarian, Nepali or Amharic one to two weeks ahead, since only a handful of qualified interpreters operate in Thailand for those pairs. Court and police assignments should be booked as soon as the date is known because the interpreter must be available for the entire session.
Can interpreting be done online?
Yes for business meetings, due-diligence calls and many consultations, and some Thai courts allow remote hearings with an interpreter joining by video. District offices, land offices and police stations generally require the interpreter to be physically present and to sign the record, so remote interpreting is not accepted for those acts.
