## Creating a translation processor

```
auto p = sdk->CreateAudioProcessor(
    AudioParams::WithLanguages("en-US", "es-ES", 16000), rc,
    onState, onTranscript);
```

## Language code format

Language codes follow BCP-47 format: `language-REGION`, for example "en-US", "es-ES", "ar-SA". Pass "*" as the source language for automatic source-language detection.

## Supported languages

The exact set available to your account is determined by Portal entitlements. Commonly available languages:

## Auto source-language detection

```
AudioParams::WithLanguages("*", "fr-FR", 16000)
```

## Conversation ID

A conversation ID ties a stream to a named session. The SDK auto-generates a UUID if you leave it empty. When calling `UpdateLanguageConfig` to switch languages on a live processor, use the same conversation ID that was set at creation time — do not generate a new one.

## Changing languages on a live stream

You can switch the language pair on a `kReady` processor without closing the connection.

```cpp
// conversationId = same value used when processor was created
LanguageConfig cfg("en-US", "fr-FR", conversationId);
UpdateLanguageResult r = processor->UpdateLanguageConfig(cfg);
// check: kSuccess / kProcessorNotReady / kInvalidParameters / kFailed
```
