NSSpeechSynthesizerMBS.IsSpeaking as boolean

true when the receiver is generating synthesized speech, false otherwise.
(Read only property)

NSSpeechSynthesizerMBS.rate as Double

dim s as NSSpeechSynthesizerMBS
s=new NSSpeechSynthesizerMBS
MsgBox str(s.rate)
// shows e.g. "160"

Mac OS X 10.5 only.
The range of supported rates is not predefined by the Speech Synthesis framework; but the synthesizer may only respond to a limited range of speech rates. Average human speech occurs at a rate of 180 to 220 words per minute.

Some examples using this property:

• /MacCocoa/Speech/NSSpeechSynthesizer

NSSpeechSynthesizerMBS.Voice as string

dim s as new NSSpeechSynthesizerMBS
MsgBox s.voice
// shows e.g. "com.apple.speech.synthesis.voice.Zarvox"

(Read and Write property)

NSSpeechSynthesizerMBS.volume as Double

dim s as new NSSpeechSynthesizerMBS
MsgBox str(s.volume)
// shows e.g. 1

No sound is zero, full sound one.
Mac OS X 10.5 only.

Volumes are expressed in floating-point units ranging from 0.0 through 1.0. A value of 0.0 corresponds to silence, and a value of 1.0 corresponds to the maximum possible volume. Volume units lie on a scale that is linear with amplitude or voltage. A doubling of perceived loudness corresponds to a doubling of the volume.

Setting a value outside this range is undefined.
