# init(mlModel:)

Creates a request that uses a custom sound classification model.

```
init(mlModel: MLModel) throws
```

## Parameters

`mlModel`

A Core ML sound classification model.

## Discussion

The model you provide must accept audio data as input and produce a classification dictionary output that contains the probability of each category. For example, you can generate a sound classifier model by creating an <doc://com.apple.documentation/documentation/CreateML/MLSoundClassifier> and training it with your own audio files.
