# INSpeakable

Pronunciation hints for strings used in a spoken interface.

```
protocol INSpeakable : NSObjectProtocol
```

## Overview

The [`INSpeakable`](/documentation/Intents/INSpeakable) protocol is adopted by the [`INSpeakableString`](/documentation/Intents/INSpeakableString) class and used to provide pronunciation hints for strings spoken by Siri. You do not need to adopt this protocol in your own classes. Instead, create instances of the [`INSpeakableString`](/documentation/Intents/INSpeakableString) class and use them when resolving parameters in your intent handlers.
