Voice, language & Spanish detection

Pick the voice your callers hear, and decide whether your agent should switch to Spanish when a caller speaks it. Both are on the same tab, and both are available on every plan.

Choosing a voice

AI Agent → Voice & Language — the Voice Selection card. Eight voices, five female and three male:

Caroline, Jacqueline, Cathy, Jessica, Skylar
Daniel, Ronald, Austin

Every voice card has a Play button that previews a real sample — listen before you decide, because a voice that reads well as a description can land differently in your ear.

Selecting a different voice reveals Save/Cancel in the card header. The change isn't live until you save it, and it takes effect on the next call.

All eight are available on every plan. There's no per-voice upgrade and no premium tier of voices — whatever descriptor sits under a card, every voice is selectable by everyone.

Automatic Spanish detection

Same tab, the Automatic Spanish Detection card. Available on Starter, Growth and Scale alike, and off by default. The toggle saves immediately — there's no Save button on this one.

With it on, your agent listens to how the caller starts speaking, settles on English or Spanish, and then responds in that language for the rest of the call.

It commits once, early — and doesn't switch back

This is deliberate, and worth knowing before you turn it on. The language is decided from the caller's first few words and then locked for the remainder of that call. A caller who opens in Spanish and drops in an English word halfway through won't flip the agent mid-sentence; nor will one who opens in English and switches later.

Predictable beats clever here: an agent that changes language mid-conversation, including changing voice mid-answer, is a worse experience than one that picks a lane and stays in it. The next call starts the decision fresh.

Spanish uses one fixed voice

Your chosen voice above applies to English calls. Spanish calls use a single Spanish voice — there's no separate Spanish voice picker.

What gets translated, and how

Your business description, tone and advanced instructions stay written in English. On a Spanish call they're translated live rather than read from a separate Spanish version you'd have to maintain. That means turning it on costs you no extra writing — but the Spanish your callers hear is a real-time translation of your English, so it's strong rather than perfect, and it's worth testing with a Spanish speaker before relying on it heavily.

Your knowledge base is handled differently, because searching English text for a Spanish question works badly. When you switch the toggle on, everything already in your knowledge base is translated into Spanish and stored alongside the English — not instead of it. While the toggle stays on, anything you add afterwards gets both versions automatically. A Spanish call searches the Spanish text; an English call searches the English.

Before you turn it on

Make a browser test call in Spanish and listen to how your business description comes out.
Check the specifics in your knowledge base — names, part numbers and prices are where a translation is most likely to read oddly.
Remember your greeting is still spoken in whatever language you wrote it, since it happens before the caller has said anything to detect from.
