# SpeechTranscriber.Preset

Predefined transcriber configurations.

```
struct Preset
```

## Overview

You can configure a transcriber with a preset, or modify the values of a preset’s properties and configure a transcriber with the modified values. You can also create your own presets by extending this type.

It is not necessary to use a preset at all; you can also use the transcriber’s designated initializer to completely customize its configuration.

This example configures a transcriber according to the `timeIndexedTranscriptionWithAlternatives` preset, but adds etiquette filtering and removes alternative transcriptions:

```swift
let preset = SpeechTranscriber.Preset.timeIndexedTranscriptionWithAlternatives
let transcriber = SpeechTranscriber(
    locale: Locale.current,
    transcriptionOptions: preset.transcriptionOptions.union([.etiquetteReplacements])
    reportingOptions: preset.reportingOptions.subtracting([.alternativeTranscriptions])
    attributeOptions: preset.attributeOptions
)
```

This table lists the presets and their configurations:
