Set the embedded speech command delimiter characters to be used for the synthesizer. An NSDictionary object that contains the delimiter information. See “Command Delimiter Keys” for the keys you can use to specify values in this dictionary.

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 (as empty strings). See “Speech Command Delimiter” for the keys you can use to specify values in this dictionary.

This property works with setObject:forProperty:error:.
