# Frequently Asked Questions

> Answers to common questions about Anam

### How is usage time calculated and billed?

Usage time starts when you call the `stream()` method and ends when that specific stream closes. The time is tracked in seconds and billed per minute.

### What causes latency and how can I optimize it?

Latency can come from several sources:

* Connection setup time (usually 4-5 seconds, but can be up to 10 seconds)
* LLM processing time
* TTS generation
* Face generation
* Network conditions

To optimize latency:

* Consider using our turnkey solution instead of custom-LLM
* Use the streaming API for custom LLM implementations

### How do I handle multilingual conversations?

Anam supports multilingual conversations across 70+ languages. To configure:

1. **Set the transcription language**: Add `languageCode` to your persona config when creating a session token (e.g., `"languageCode": "fr"` for French)
2. **Choose a matching voice**: Select a voice in your target language from the [Anam Lab](https://lab.anam.ai)
3. **Write your system prompt**: Instruct the persona to respond in the target language

For detailed configuration and supported languages, see our [Multilingual Support guide](/concepts/multilingual).

### Can I interrupt the persona while it's speaking?

Yes, you can interrupt the persona in two ways:

1. When using streaming, user speech will automatically interrupt the current stream
2. Use the `interruptPersona()` method to programmatically stop the persona mid-speech. See the [interrupt command](/sdk-reference/interrupt-command) for more information.

### How do I integrate my own LLM?

See our [custom LLM guide](/concepts/custom-llms) for more information.

### What are the browser compatibility requirements?

The SDK should work well with any recent Chromium-based or Firefox browser. It requires:

* Modern browser with WebRTC support
* Microphone permissions for audio input
* Autoplay capabilities for video/audio
* WebAssembly support

Safari/iOS notes:

* Requires explicit user interaction for audio playback
* May have additional security policy requirements
* WebKit engine has specific autoplay restrictions

### How do I monitor current usage?

Usage tracking options:

* Available in Anam Lab
* API endpoint for usage stats coming soon
* Session logs available in the Anam Lab

### How do I handle connection issues?

Common issues and solutions:

* For "403 Forbidden" errors, verify API key/session token
* If video doesn't appear, check element IDs match exactly
* Connection timeouts may require retry logic
* Session tokens expire and need refresh
* Monitor `CONNECTION_CLOSED` events for network issues
