The 30 voices
Voices are grouped into seven families. Every voice speaks every supported language, so picking a voice never limits your language choice.
| Family | Suits | Voices |
|---|---|---|
| Authoritative | Business reception, financial services, healthcare, legal | Charon, Rasalgethi, Sadaltager, Kore, Orus, Alnilam |
| Bright/Upbeat | Consumer brands, retail support, sales | Zephyr, Puck, Autonoe, Laomedeia, Sadachbia |
| Energetic | Younger audiences, entertainment, high-volume support | Fenrir, Pulcherrima, Leda |
| Casual | Friendly consumer support, hospitality, food and drink | Aoede, Callirrhoe, Umbriel, Zubenelgenubi, Achird |
| Soft/Warm | Wellbeing, after-hours support, premium service brands | Achernar, Vindemiatrix, Sulafat, Enceladus |
| Clear/Smooth | Technical support, replacing a phone menu, formal corporate | Iapetus, Erinome, Algieba, Despina, Schedar |
| Distinctive | Memorable, character-led brands | Algenib, Gacrux |
Each voice also carries a one-word descriptor next to its name in the picker — Firm, Bright, Breezy, Gravelly and so on — and is marked female or male. The default is Kore, a firm female voice in the Authoritative family, and it is a safe pick if you are undecided.
How to preview a voice
Open the agent from Brand → Voice and go to the Voice & language tab. Filter by name or descriptor if you like, then press play on any card. If you have already written a begin message, the sample speaks your actual greeting in the selected language, so you hear exactly what a caller will hear; if you have not, it speaks a standard sample sentence instead.
One small caveat: each preview generates a short piece of speech, so it counts as a tiny amount of AI usage. Not enough to think about, but not literally free.
Match the voice to your brand, not to the country. A premium watch brand does not want a different personality in German than in English — it wants the same personality speaking German. Pick the family that fits how you sound, and keep it across every language agent you set up.
The 17 languages
| Language | Code |

The language you pick decides the default greeting and the language the agent replies in. It is a per-agent setting, not a per-number one.
If your callers speak more than one language
An agent has one language. If you serve callers in several, the reliable arrangement is one agent per language, each with its own phone number, and callers choose by dialling the right number. That also lets you write a different greeting and a different persona for each audience, which usually reads better than one agent trying to cover everyone.
Transcripts in languages other than English
Non-English calls are written up by a different transcription engine, automatically and with nothing for you to set. It affects the written record only — the spoken conversation is unchanged, and the agent's understanding, its tool use and its replies all work exactly as they do in English.
What to read next
Give the agent something worth saying: What your voice agent knows, and where that knowledge comes from.
