An AI voice agent that speaks German.
A German agent writes each reply in German and speaks it in a Cartesia Sonic voice, with GPT Transcribe hearing the caller. It suits a Mittelstand support line, a practice’s booking desk or a talk button on a German-language site.

A greeting as the agent writes it, in Latin script, before the voice speaks it.

Questions.
Can a German caller use English words?
Yes. Every agent listens for English as well as its own language, so a sentence that mixes the two is understood.
Can one agent take calls in German and in other languages?
Yes, in two ways. Save the agent in German and every call starts in it. Or keep the agent as it is and hold one call in German by sending language: "de" when you start it. The agent’s voice must be Cartesia Sonic; any other voice is answered 400 UNSUPPORTED_LANGUAGE.

What does a call in German cost?
The same as in any other language: $0.07 a minute, whichever voice and model, billed by the second.
