Spanish interpretation for a conference in Phoenix or Scottsdale: simultaneous, consecutive or whispered?

For a conference in Phoenix or Scottsdale, choose simultaneous interpretation when a full room needs Spanish (or English) in real time through receivers, consecutive when a speaker can pause for short remarks or a small meeting, and whispered interpretation when only one or two listeners seated together need it.

Many people search for “simultaneous translation” or ask for “a translator for the event.” The precise word is interpreting. As the American Translators Association (ATA) puts it, “Translators do the writing. Interpreters do the talking.”

In Maricopa County, nearly one in five people age 5 and older speaks Spanish at home (19.6%), according to the Census Bureau’s 2024 American Community Survey.

Separate guides cover what equipment simultaneous interpretation needs and consulate and Mexican organization events. We cover the printed side, from the program to the slides, in what to send your interpreter.

What is simultaneous interpretation, and when does your conference need it?

It runs at the same time as the speaker. ATA’s Guide to Buying Interpreting Services describes the interpreter working “with a slight delay,” often from a booth, “transmitting to listeners wearing headsets,” and gives large industry conferences as an example. It is the mode for the general session, the keynote or a panel when part of the room needs the other language.

As a rule, the interpreter works from a soundproof booth facing the room, and each listener hears it on a receiver and headset. According to Visit Phoenix, the Phoenix Convention Center’s West Building has a 192-seat lecture hall where “assisted-listening devices provide real-time interpretations in up to four languages.”

Scottsdale has more than 70 meetings-friendly properties, according to Experience Scottsdale. Ask your resort about its AV rules before renting anything (see the equipment guide). Spanish speakers often call simultaneous interpreting “traducción simultánea,” a phrase the Real Academia Española’s dictionary lists too.

When is consecutive interpretation enough?

It is enough when the speaker can pause. In consecutive, ATA’s guide explains, “The interpreter interprets after each speaker pauses.” The guide adds: “During long statements, the interpreter takes notes to ensure accuracy.”

It works for welcome remarks, a toast, an awards segment, a short Q&A, a small meeting or a site visit. No booth is needed. At most, the interpreter needs a microphone.

The cost is time: every part is said twice. That is why consecutive suits short remarks and not an hour-long keynote.

What is whispered interpretation, and who is it for?

It is simultaneous interpreting without equipment. In ATA’s words, the interpreter “sits near the individual who needs language services and quietly interprets what is being said to avoid disturbing others in the room.” It suits one or two listeners seated together, such as a guest of honor inside an English-language session.

The professional standards of AIIC, the International Association of Conference Interpreters, as published by AIIC Italia, set their rule for whispered interpretation at “no more than two listeners” and still require “at least two interpreters.” Any other simultaneous interpreting without a booth they accept only in exceptional circumstances, when quality does not suffer.

Maricopa County courtrooms use the same two set-ups. The Superior Court in Maricopa County says the court interpreter “may hand you a set of headphones and a receiver,” or may “stand or sit close to you and whisper the rendition for you to hear without using equipment.”

Which mode fits each part of your event?

Conference interpretation services are rarely one service: each part of a conference calls for its own mode, so the interpreter needs your whole program. AIIC’s guide to tenders for conference interpreting lists what to give interpreters: the place and dates, the subject, the likely timetable, the type of interpretation and the languages.

When part of your program does not fit a row, decide the mode with your interpreter and tell them all you can. “The more information you are able to provide upfront, the more successful your collaboration will be,” ATA’s guide says. For a consulate forum or a binational meeting, read the guide to Mexican organization events.

When do you need two interpreters?

For simultaneous in a booth, as a general rule, always. AIIC’s professional standards, as published by AIIC Italia, say “a team is composed of at least two interpreters per language and per booth,” and that an interpreter should not “work either alone or without the availability of a colleague to relieve them,” because of the fatigue of sustained concentration.

AIIC’s tenders guide adds that “interpreters work in teams of two or more per output language” and are “usually contracted by the day.” In a worked example from AIIC Greece & Cyprus, each pair alternates “in 30-minute shifts.”

NAJIT, the National Association of Judiciary Interpreters & Translators, calls for a team in legal proceedings once continuous simultaneous runs past 30 minutes or consecutive past 60, a position written for legal settings. For conferences there is also an international standard of requirements and recommendations, ISO 23155:2022.

A full-day program in simultaneous is a job for a team. Didi interprets herself, and when a job needs more interpreters, she brings a trained team.

Does Arizona require a license to interpret at a conference?

Arizona’s statutes and court pages describe two interpreter credentials, each for its own field: sign language and the courts. Neither is written for Spanish and English at a private conference, and their pages do not say what applies there; that question is for an attorney.

The first is a license from the Arizona Commission for the Deaf and the Hard of Hearing (ACDHH) (A.R.S. § 36-1946): under § 36-1971, “A person shall not practice as an interpreter for the deaf and the hard of hearing without a license,” and in that chapter interpreting means moving between English and sign language or other specialized vocabularies (§ 36-1941).

The second is the Arizona Judicial Branch’s Court Interpreter Credentialing Program, which “provides for the credentialing of spoken-language interpreters only,” for work in the courts.

If a Deaf attendee is coming, book an ACDHH-licensed sign language interpreter separately (commission FAQ). For Spanish and English, also ask about experience at similar events, references, preparation and teamwork.

What does your interpreter need before the event?

Your program and your materials, early. In its tips for event planners, AIIC Greece & Cyprus asks you to send the interpreters “the conference papers, as well as any background information relating to the event,” as early as possible. ATA’s guide also asks for recordings of earlier events, so the interpreter can become familiar with the speakers.

AIIC Greece & Cyprus recommends one contact person for the interpreters and, depending on the subject, a briefing with the speakers. During the event, it asks you to keep them informed of new documents, because “the more information they have, and the earlier they get it, the better they can perform.” The full checklist is in what to send your interpreter.

What this guide does not answer

Interpreting in court and legal settings (hearings, depositions, attorney meetings) is a different service with its own rules; for Arizona’s courts, the Judicial Branch runs its own credentialing program.

This guide does not review your agreement with the venue or the AV company, and it is not legal advice: for a legal decision about your event, talk to an attorney.
