# PhonemeDescriptor

Defines a phoneme descriptor structure.

## Declaration

```swift
struct PhonemeDescriptor
```

## Overview

Overview By calling the GetSpeechInfo function with the soPhonemeSymbols selector, you can obtain a phoneme descriptor structure, which describes all phonemes defined for the current synthesizer. A common use for a phoneme descriptor structure is to provide a graphical display to the user of all available phonemes. Such a list is used only for a user entering phonemic data directly rather than just entering text.
