# SFCustomLanguageModelData.DataInsertableBuilder

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

```
@resultBuilder struct DataInsertableBuilder
```

## 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.

## Topics

### Result builder methods

[`static func buildArray([any DataInsertable]) -> any DataInsertable`](/documentation/Speech/SFCustomLanguageModelData/DataInsertableBuilder/buildArray(_:))

Enables support for `for..in` loops.

[`static func buildBlock(any DataInsertable...) -> any DataInsertable`](/documentation/Speech/SFCustomLanguageModelData/DataInsertableBuilder/buildBlock(_:))

Combines statement blocks into a single product.

[`static func buildEither(first: any DataInsertable) -> any DataInsertable`](/documentation/Speech/SFCustomLanguageModelData/DataInsertableBuilder/buildEither(first:))

Enables support for `if-else` and `switch` constructs.

[`static func buildEither(second: any DataInsertable) -> any DataInsertable`](/documentation/Speech/SFCustomLanguageModelData/DataInsertableBuilder/buildEither(second:))

Enables support for `if-else` and `switch` constructs.

[`static func buildOptional((any DataInsertable)?) -> any DataInsertable`](/documentation/Speech/SFCustomLanguageModelData/DataInsertableBuilder/buildOptional(_:))

Enables support for `if` statements that do not have an `else` clause.
