Your voice AI agent replies in the caller's language

Omnifox's voice AI agent can greet and hold a conversation in Spanish, English or Portuguese automatically, matching the caller's language — no need to build a separate flow per country.

Requirements

• Crece or Escala plan (voice AI isn't available on Lite/Conecta).
• A connected calling channel with an AI Agent enabled for calls.
• A voice configured for each language you support.

Set up voices per language

1. Go to AI Agents → open your agent → the Voice tab.
2. Under "Voices by language", assign an ElevenLabs voice for Spanish, English and Portuguese.
3. Set a "default voice" as a fallback for any language you haven't configured yet.
4. Use the Test button to preview a sample before saving.

How the call decides the language

• If your IVR includes the "Detect language" node, it reads the caller's phone country code (Brazil/Portugal → Portuguese, US/Canada/UK/Australia/New Zealand → English, everything else → Spanish) and stores it.
• If you'd rather ask, build a menu ("Press 1 for español, 2 for English…") with a Wait for digit block and store the choice.
• On the "Route to AI agent" node, leave Language set to "auto" so it picks up the detected value, or fix it to es/en/pt if that IVR always serves a single language.

Example

A caller dials in from +55 11 9xxx (Brazil). The Detect language node stores "pt". The Route to AI agent node has Language = auto, so the agent greets and answers in Portuguese, using the voice you configured for that language.

Tips

• Always set a default voice, even if you fill in all three languages.
• Test every language with a real call before publishing.

Troubleshooting

• Agent always answers in Spanish: check that Detect language sits upstream of Route to AI agent in the flow, and that node's Language field is set to "auto".
• No Voice tab on the agent: your plan doesn't include voice AI — upgrade to Crece or Escala.
