# SFCustomLanguageModelData.DataInsertableBuilder

A custom parameter attribute that constructs custom language model data from closures.

## Declaration

```swift
@resultBuilder struct DataInsertableBuilder
```

## Overview

Overview The SFCustomLanguageModelData class provides two methods for accumulating data: manually constructing PhraseCount and CustomPronunciation objects and providing them using the insert methods defined below, or by using the result builder DSL upon initialization. This type supports the latter.
