Live interpretation has no room for a second take.

Because an interpreting booking buys reserved availability, not elapsed speaking time. The interpreter holds the whole window and cannot take other work in it, which is the cost being covered whether the session runs long or ends early. That is also why a rate for a standby or on-call role does not flex the way a per-word rate does — the commitment is the product.

Depending on the engagement: per hour for scheduled sessions, per minute for on-demand phone and video work, per day for standby shift models, and a single fee for a multi-session assignment. Ask for the rounding rule explicitly — on per-call pricing the difference between a ten-minute and an eleven-minute call is a whole billing increment, and that boundary is where interpreting invoices most often surprise people.

OPI is over-the-phone and connects fastest, suiting short unscheduled exchanges. VRI is video remote, and is warranted whenever visual context carries meaning — a document, an object, a procedure — and for any exchange where facial expression matters. Consecutive means the interpreter speaks in the gaps and roughly doubles elapsed time; simultaneous runs live and needs two interpreters for anything beyond about an hour, because sustained simultaneous work is not something one person can hold quality on. Sign language interpreting sits outside that spoken-language grid rather than being a variant of it: it is booked as its own modality, ASL and international sign are not interchangeable, and a signed session is specified by the sign language required rather than by the spoken language in the room.

Yes, and for legal and medical assignments you should insist on it rather than accept general fluency. Court work routinely requires certification or registration with the relevant state or national body, and healthcare settings commonly ask for a recognised medical interpreter credential alongside privacy training. Tell us the credential the setting requires and evidence is supplied with the interpreter, not after the booking.

To whatever standard the platform demands, which for enterprise programmes is usually stricter than a normal video call: a wired network connection rather than wireless, a wired headset, a stated minimum bandwidth in both directions, a neutral background, and professional presentation on camera. Where a buyer supplies a technical or dress specification, interpreters are briefed to it before the first session rather than corrected after it.

Often, and it works differently from translation. Rare-language interpreting is an availability problem before it is a scheduling one, so feasibility is confirmed first and the timeline is built around when a qualified interpreter can actually be booked. For the rarest pairs a scheduled session with a stated lead time is honest where an on-demand commitment would not be — a handful of qualified interpreters worldwide cannot support an instant-connect promise, and saying so early is worth more than discovering it live.

You are told before a date is agreed, not after. Coverage is reported pair by pair as staffed today or needing a recruitment window, with the window stated — in writing, while the scope is still being agreed. Nobody new goes onto live work until a pilot batch has been reviewed and signed off. A coverage claim you cannot check before signing is not coverage.
