How to handle multilingual calls with an AI voice agent
If your callers speak more than one language, your voice agent should meet them in theirs. A little planning makes that smooth.
Step 1. Find out which languages your callers use
Look at your own call history and ask your team. Start with the languages you hear most, then add others as demand grows.
Step 2. Pick the agent's languages
InfiVoice supports 30+ languages. Choose the ones that match your callers instead of enabling everything at once.
Step 3. Write the greeting for each language
Do not just translate word for word. Write a short, natural greeting the way a person at your business would say it in that language.
Step 4. Prepare your knowledge base in each language
Keep answers about hours, services and policies consistent across languages. If the facts differ between versions, callers will notice.
Step 5. Decide how callers choose a language
You can open in your main language and offer a switch, or let the agent adapt to the language the caller speaks. Pick the option that fits your audience.
Step 6. Plan the handoff
If a caller needs a person, make sure someone who speaks their language can take the call, or collect a callback request in that language.
Step 7. Test with native speakers
Ask people who speak each language to call the agent. They will catch phrasing, names and pronunciations that you might miss.
What it costs
InfiVoice bills in credits, and one credit equals 60 seconds of call time. The Free plan includes 100 credits. Pro costs $79 per month with 250 credits.
Frequently asked questions
Do I need a separate agent per language?
Not necessarily. Many setups use one agent that handles several languages. Test to see what works for your callers.
Which language should I add first?
The second most common language among your callers.
How do I check quality in a language I do not speak?
Ask a native speaker to review transcripts and place a few test calls.
