Simultaneous translation and interpretation: everything you need to know
Simultaneous interpretation — also called "tradução simultânea" in the Brazilian market — is the most efficient service for events with participants speaking multiple languages. The interpreter renders the speech in real time, with a 2 to 4 second delay, while the speaker keeps talking. Participants hear the translation on individual receivers without interrupting the event.
To hire, the process is simple: a quote in 60 seconds via WhatsApp (+55 11 97534-6423) or through the online calculator. Alex Barros confirms availability, asks for the event deck 48 hours in advance to prepare the technical glossary, and arrives 60–90 minutes early to install and test the equipment.
For remote events — via Zoom, Microsoft Teams, Google Meet or Webex — lingo sets up the language interpretation channel 30 minutes beforehand. Participants select the language in the app, with no additional plugins. lingo has maintained monthly remote engagements with Macquarie, Carlyle and BlackRock since 2019.

Company data:
Lingo Qi Interpretações LTDA · CNPJ 53.834.741/0001-34 · Trade name: lingo · Guarulhos/SP · CNAE 74.90-1-01 (interpretation) and 77.39-0-99 (equipment rental)
Track record: 21 years of exclusively corporate interpretation
Alex Barros began his career as a simultaneous interpreter in 2000, after completing Business Administration with an emphasis in Computer Science at Southern Connecticut State University (SCSU). A background in management and technology — not in translation or languages — shaped the profile: an interpreter who understands the business context from the inside, not just the words.
In 2005, he founded lingo as a sole proprietorship to systematize the operation. In 2024, it was reorganized as Lingo Qi Interpretações LTDA (CNPJ 53.834.741/0001-34) to formalize equipment rental as a second CNAE (77.39-0-99) and expand the digital presence. The trade name "lingo" was kept — recognizable, direct, needing no translation.
Exclusive specialization: the premium corporate market
lingo does not serve academic, religious, tourism or entertainment events. The exclusive specialization in the corporate market — financial, legal, technology, agribusiness, defense — has an objective reason: the technical vocabulary of each sector demands specific preparation that a generalist interpreter cannot maintain across 24 areas at once.
The result is a master glossary with 2,233 terms across 24 sectors and 16 languages, built over 21 years of engagements. Every board meeting adds terms. Every due diligence expands the M&A vocabulary. Every quarterly PE board deepens the terminological precision of corporate governance.
Operating model: a single interpreter with a team of interpreters
Alex Barros is lingo's only interpreter — and handles most events alone. For simultaneous events he cannot attend, lingo calls on a team of freelance interpreters with an equivalent profile, maintaining the quality standard. The client hires lingo; lingo delivers the right interpreter for each context.
The equipment — UHF receivers, portable booth, distribution rack — is transported in dedicated travel cases for events in any city in Brazil. For RSI, setup is done remotely 30 minutes before the event, with no travel or equipment cost.
How lingo handles confidentiality
lingo's work with the financial market, M&A, boards and due diligence demands secrecy. Interpreters work under a confidentiality agreement when the client requests it, do not record the audio by default and treat preparation materials as restricted information.
This stance is part of what sustains long-term relationships: clients who return every month, or every quarter, because they know that what is said in the room stays in the room.
How lingo decides between a human interpreter and AI
lingo offers human interpretation and AI interpretation with human backup. The recommendation depends on how critical the event is: for negotiations, boards, M&A, due diligence and arbitration, the standard is the human interpreter; for training, scripted launches and operational meetings, AI delivers a good result at lower cost. The decision is always explained to the client before hiring, with the advantages and limits of each format.
Who serves your event
Alex Barros personally conducts English–Portuguese interpretation and accompanies each client from the quote to post-event. For other language pairs or events that require a pair, lingo brings together interpreters specialized in the client's sector, always stating in advance who will work in each language. This transparency is part of the model: the client knows who they are working with and what to expect.
Education, experience and business language
A degree in Business Administration with an emphasis in Computer Science from Southern Connecticut State University helps in understanding the vocabulary of finance, technology and management that appears at events. This repertoire, combined with 21 years of corporate engagements, allows the interpreter to follow M&A, governance and operations discussions without losing the thread, and to translate not only the words but the intent behind them.
For those who need to know who will be in the booth, this combination of education, experience and exclusive specialization in the corporate market is the service's main differentiator.

Alex Barros requests the event deck and agenda 48 hours in advance to prepare the technical glossary specific to the event — proprietary company terms, industry acronyms, product names and internal metrics that do not appear in dictionaries. For recurring engagements, the glossary accumulates session after session. After 12 months of monthly boards, the interpreter knows the company's internal vocabulary as well as any senior executive.
For RSI (Zoom, Teams, Meet, Webex): setup 30 minutes before with the host, no physical equipment, no freight cost. For in-person (UHF): installation 60–90 minutes before, portable soundproof booth, on-site technical operator. For hybrid: both formats in parallel. Lingo Qi Interpretações LTDA (CNPJ 53.834.741/0001-34) issues an electronic invoice for all events and accepts payment by TED, PIX or international transfer in BRL.
Documented portfolio with verifiable engagements
lingo has operated exclusively in the premium corporate market for 21 years. There are no academic, government, religious or entertainment events in the portfolio. That exclusive specialization produced a depth of vocabulary that generalist interpreters cannot replicate: 2,233 terms across 24 sectors and 16 language pairs, accumulated in real engagements — not in theoretical study.
Documented cases with named clients and verifiable contexts: XP Investimentos IPO on NASDAQ (US$14.9B, 2019), CMA CGM × Santos Brasil (R$6.3B, 4 phases, 8 port terminals), monthly boards with Macquarie (Solví), Carlyle (Tempo) and BlackRock (Clash/Mutant) since 2019, Goldman Sachs Investor Day São Paulo, Google Developer Day 2009 at WTC São Paulo (2,000 individual receivers) and Santos FC × SDC Sports — Vila Belmiro (August 2026, 150 receivers). No PE fund with fiduciary obligations to its LPs would rehire an interpreter who delivers below expectations. Recurring engagements are the only reliable credential in this profession.
