Interpreter is one of Microsoft's smaller but most impactful agents — real-time speech-to-speech translation in Teams meetings, up to nine languages. Everyone speaks their own language and hears everyone else's translated to theirs. The agent does the hard part; the skill you bring is speaking in a way the translation can carry cleanly.
Step 1 of 50% complete
The mental model
The agent translates — you make it translatable
Interpreter handles the part that used to need a human translator: each person speaks their native language, everyone hears theirs, captions follow along. What it can't fix is how you talk — and that's where most of the quality comes from.
Predict first
Interpreter is on for a call with a customer in another language. Beyond switching it on, what most improves how well it goes?
Setup
Configure it before the call
Add Interpreter from the Copilot meeting tools when scheduling.
Set your own language — everyone else's speech arrives translated to it. Language preference is per-person.
Note in the invite that translation will be on, so people know what to expect.
Optionally enable voice-matching so the translated audio sounds like the original speaker — it feels far more natural on customer calls.
Interpreter only works on supported languages. Confirm yours is on the current list before you build a critical meeting around it — the list expands often, so check in Teams admin settings.
Do it · de-idiom it
Idioms are translation kryptonite
Interpreter translates what you literally say. Idioms get rendered word-for-word into something baffling — "circle back" becomes an image of going in circles. Here's an opener a rep might use. Tap each highlighted idiom to swap it for a version the translation can carry.
You, on a multilingual customer call
"Let's on the project, get a on the timeline, and next week if anything's still ."
0 of 4 idioms fixed — tap the highlighted ones.
The combo + one check
Pair it with Facilitator for notes in every language
Run Interpreter and Facilitator together: Facilitator writes the summary and action items, Interpreter translates them, and each attendee gets the notes in their own language automatically. "We need translated meeting notes" stops being a follow-up task.
The payoff
Everyone leaves a cross-border meeting with a recap and their action items already in their language — no translator, no delay.
One thing to check first
Your combined setup auto-translates the action items into everyone's language. Before you rely on them, what's the right move?

Language stops being the thing that blocks the meeting
What you can do now
Confirm your language is supported before relying on Interpreter
Speak plainly and a touch slower — strip idioms and slang
Turn on voice-matching for a more natural customer-facing feel
Pair Interpreter with Facilitator for notes in every attendee's language
Spot-check translated action items — small ambiguities get big across languages
Your move: run one multilingual meeting this month
If you have international customers, partners, or teammates whose first language isn't yours, schedule a call with Interpreter on. Speak plainly, watch the idioms, and notice which conversations become possible that weren't before.
