## Declaration

```swift

```

## Discussion

Discussion Set the embedded speech command delimiter characters to be used for the speech channel. By default the opening delimiter is “[[” and the closing delimiter is “]]”. Your application might need to change these delimiters temporarily if those character sequences occur naturally in a text buffer that is to be spoken. Your application can also disable embedded command processing by passing empty delimiters (using two NUL ASCII characters).The speechInfo parameter is a pointer to a delimiter information structure, described in DelimiterInfo. This selector works with the SetSpeechInfo function.
