kSpeechCommandDelimiterProperty
Set the embedded speech command delimiter characters to be used for the speech channel.
Declaration
let kSpeechCommandDelimiterProperty: CFStringDiscussion
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). The value associated with this property is a CFDictionary object that contains the delimiter information. See Command Delimiter Keys for the keys you can use to specify values in this dictionary.
This property works with the SetSpeechProperty(_:_:_:) function.
