# Multilingual

> Languages, voices, and cross-locale behavior

MrAssistant AI targets **multilingual** experiences: callers may start in one language and switch to another, or require locale-specific voices and ASR models.

## Language matrix

The API exposes **supported languages** and a **matrix** that helps you pair STT, TTS, and LLM capabilities. Start from the matrix when you design a new agent.

## Voices

List voices per provider, search catalogs when available, and align **voice options** with your brand and accessibility goals.

## Conversation behavior

* Prefer **explicit language confirmation** when ambiguity is costly (for example finance or healthcare).
* Keep **fallback** providers configured where the API supports it, so a single provider outage does not drop the call.
