Level Up
One Agent, Many Languages: Architecting Multi-Lingual Voice AI
Your customers don't all speak the same language — so how do you build a single voice AI agent that greets a caller in one language, gracefully switches mid-call, and stays coherent throughout?
In this Level Up webinar, we'll build and unpack the architecture behind multi-lingual voice AI on Twilio ConversationRelay. We'll cover language detection strategies, choosing the right STT and TTS provider stack, handling mid-call language switching, and the prompt patterns that keep an LLM-driven agent grounded when the conversation crosses languages.
What you'll learn:
- Detect caller language and switch in real time using Twilio ConversationRelay
- Choose the right STT and TTS provider stack for your target languages
- Structure prompts and context so your agent stays coherent across language switches
- Design fallbacks for unsupported languages and uncertain detection
