When every word has to land
Conference interpreter based in Rio de Janeiro, providing simultaneous interpretation for events in Brazil and abroad.

About
Good interpreting goes beyond words
In 1945, at the Nuremberg trials, four languages shared the same courtroom. Every testimony had to be understood almost the moment it was spoken, and a single error could change a human being's fate. Decades later, in very different settings, the challenge remains.
An interpreter's work is to understand not only what is said but what is meant: reading between the lines, the tone and the intent of the speaker, and preserving them for the listener.

Frequently asked questions
Questions about simultaneous interpreting, interpreters and equipment
Does the proposal include interpreting equipment?
It depends on your event’s needs. The proposal can cover interpreters only or the complete interpreting setup: booths, electronic equipment, audience receivers, technicians and staff to distribute and collect the receivers.
The event’s sound system — including microphones, speakers and a mixing console — is usually provided by the venue. These arrangements are confirmed during planning, so it is clear what is included and what needs to be arranged separately.
Are simultaneous translation, simultaneous interpretation and live translation the same service?
In the context of events, these expressions usually describe speech being interpreted into another language in near real time, without interrupting the event. Within the profession, simultaneous interpretation is the more precise term. “Live translation” is also used informally.
Does an event require one interpreter or a team?
This mainly depends on the event’s duration, format, subject matter and languages.
What information is needed for a proposal?
Date, duration, location or online platform, languages, subject, expected audience and any equipment requirements. These details make it possible to define the right setup without adding unnecessary services.
