# WAAccessCategory.interactiveVoice

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

```
case interactiveVoice
```

## 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.
