# CXSetTranslatingCallAction

An encapsulation of the act of translating a call.

```
class CXSetTranslatingCallAction
```

## Overview

[`CXSetTranslatingCallAction`](/documentation/CallKit/CXSetTranslatingCallAction) is a concrete subclass of [`CXCallAction`](/documentation/CallKit/CXCallAction). When a caller chooses to translate a conversation, the system
provides translated captions, and a translated transcript of the call and the [`CXProvider`](/documentation/CallKit/CXProvider) sends the
[`provider(_:perform:)`](/documentation/CallKit/CXProviderDelegate/provider(_:perform:)-43atg) to its delegate. The provider’s delegate calls the [`fulfill()`](/documentation/CallKit/CXAction/fulfill()) method
to indicate that the action was successfully performed.

> Important: To avoid interrupting or impeding call translation when a person mutes their audio during a conversation, don’t deactivate the upstream audio. Instead, mute your app’s audio input using ``doc://com.apple.callkit/documentation/CallKit/CXSetMutedCallAction`` and keep the upstream audio active to allow translated audio to flow when a person mutes the hardware microphone.
