# relativeAudioSourceReference

The relative audio source to select.

## Declaration

```swift
var relativeAudioSourceReference: INRelativeReference { get }
```

## Discussion

Discussion When the user asks for the next or previous audio source, Siri fills this property with an appropriate value. However, if the user asked for a specific audio source, instead of the next or previous one, Siri sets this property to INRelativeReference.unknown.
