Best German Voice Model

Hi everyone 👋
I’m currently building an AI phone assistant for HR / candidate screening interviews and wanted to ask for your experience and recommendations.

What do you think is the best voice model for a phone-based interview assistant in German?
Key requirements for this use case are:
• natural and professional tone
• neutral but empathetic delivery
• good German pronunciation
• low latency for live conversations
• stability over ~10–15 minute calls

If you’ve tested different voice models (e.g. ElevenLabs, Cartesia, Azure, Rime, Vapi voices), I’d love to hear:
• which model you chose
• why you chose it
• any trade-offs you noticed (latency vs. naturalness, etc.)

Thanks a lot in advance! 🙏
