Multi-language voice support helps your AI agent serve customers who do not use your primary language. It combines three settings: the primary language, additional languages, and language detection.
The three pieces
Primary language is the agent's default language. It determines the primary voice list and is the language Speako starts from.
Additional languages are the extra languages you allow the agent to understand. These are selected in the Additional languages panel.
Enable Additional Languages turns on language detection so the agent can recognise an enabled language during a call and respond accordingly.
All three live under AI Agent → Voice & Languages → Voice & Languages.
Voice behaviour
Depending on your voice setup, additional languages may work in one of two ways:
- each enabled language can have its own selected voice
- the primary voice is reused across all enabled languages
The Additional languages panel tells you which experience applies. If it asks you to assign a voice for each language, choose one from the dropdown. If it says the primary voice is reused, focus on selecting the languages only.
What customers experience
When a customer calls in an enabled additional language, Speako can detect that language and respond in it. This is designed for customer-facing conversations such as asking questions, getting information, or making bookings.
💡 Tip: Keep your Knowledge Base up to date in the languages your customers need. Voice and language settings control how the agent speaks, but the quality of the answer still depends on the business information you provide.
Common setup mistakes
- Enabling additional languages but not selecting any languages
- Selecting languages but forgetting to save
- Setting the wrong primary language, which changes the voice list
- Assuming all languages have the same voice choices
Saving
Language support changes are staged until you select Save Changes in the bottom banner. If you leave the page or switch location with unsaved changes, Speako warns you so you do not lose work accidentally.
After saving, place a test call or preview relevant voice settings if your workflow supports it. Listen for the basics first: the primary language, the selected voice, and whether the language choices match the customers you expect to serve.
