kSpeechNumberModeProperty

Declaration

let kSpeechNumberModeProperty: CFString

Discussion

The value associated with this property is a CFString object that specifies whether the speech channel is currently in normal or literal number-processing mode. The constants kSpeechModeNormal and kSpeechModeLiteral (defined in Speech-Channel Modes for Core Foundation-based Functions) are the possible values of this string.

When the number-processing mode is kSpeechModeNormal, the synthesizer assembles digits into numbers (so that “12” is spoken as “twelve”). When the mode is kSpeechModeLiteral, each digit is spoken literally (so that “12” is spoken as “one, two”).

This property works with the CopySpeechProperty(_:_:_:) and SetSpeechProperty(_:_:_:) functions.
