Interpretation happens out loud, in real time, while people are talking. Translation happens on the page, after someone has already written something down. On a call, that difference decides whether the other person hears a response in a couple of seconds or has to wait for a document to come back.
A translated document can sit for an hour and lose nothing. A phone call can't. If someone asks a question in Spanish and the answer takes ten seconds too long, the call stalls, the caller repeats themselves, or the agent guesses. Interpretation tools are built around that constraint — they process audio as it arrives and speak back a rendered version within a second or two, not after the sentence has been transcribed, translated, and read aloud by a person.
Over-the-phone interpretation (OPI) has traditionally meant conferencing in a human interpreter, which adds a third party to every call and a per-minute rate on top of agent time. Translatigo runs as a Chrome extension, so it sits inside whatever web-based dialer or softphone a team already uses — Avaya, Five9, Genesys, RingCentral, and similar platforms — without a separate integration. Interpretation happens directly in the call, at $0.07 per minute, with a 20-minute free trial to hear it on an actual call before switching over.
Translation stays the better fit for anything that doesn't need to happen live: contracts, emails, help-center articles, anything someone will read rather than hear. There's no reason to force a written workflow through a voice tool just because both fall under "language technology" — match the tool to whether the content is spoken or written.
