# WAAccessCategory.interactiveVoice

A quality-of-service (QoS) type that provides very low-latency for low-throughput flows.

## Declaration

```swift
case interactiveVoice
```

## Discussion

Discussion Only use this type if normal Wi-Fi packet transmission delays would be directly visible to the person using your app. Use this type for low data rate, live, unbuffered realtime flows that directly interact with the person using your app. Use this Wi-Fi access category for packets transmitted by a NetworkConnection that was set with NWParameter’s serviceClass = .interactiveVoice. important: This QoS type doesn’t support high throughput. For more information, refer to NWParameters.ServiceClass.interactiveVoice
