​
How It Works

When you select a language, a specialized prompt prefix is automatically prepended to your system prompt on save.
1

You write your prompt

You are a customer support agent for Acme Corp.
Help customers with their orders.
2

Language wrapper is prepended

You are a Yoruba realtime voice assistant.

Rules:
- Prefer Yoruba in your replies.
- If the transcription is noisy, mixed, or incomplete,
  infer the user's intent from context before answering.
- If the user switches language, follow them.
- Keep replies short, natural, and speech-friendly.

Caller: “Hello, e se, what is my balance?” Assistant: “Se o n bere nipa balance re ni?”

​
What Each Wrapper Does

Every language wrapper instructs the AI to:
  • Prefer the target language in responses
  • Handle noisy transcription — infer intent from context instead of refusing
  • Follow language switches — if the caller switches to English, follow them
  • Keep replies speech-friendly — short, natural, not robotic
  • Ask clarifying questions — when meaning is unclear, ask instead of guessing

​
Auto-Detect Mode

The Auto-Detect wrapper is multilingual. It:
  • Listens to the caller’s utterance and infers the language
  • Supports all listed languages + English
  • Doesn’t lock onto a language too aggressively
  • Follows the caller if they switch mid-conversation
Use Auto-Detect when your callers might speak different languages. Use a specific language when you know your audience.

​
Disabling

Select None from the language dropdown to remove the wrapper entirely. Your system prompt will be used as-is.

​
Best Practices

If you select Yoruba as your language wrapper, ensure your transcriber is also set to a provider that supports Yoruba (e.g., Spitch).
The wrapper already handles language behavior. Your prompt should focus on the task, not language instructions.
