tts_voice object
int volume
This determines how loudly the voice will speak. 0 is the original volume, and -100 is completely silent. This is set to -1 on error. Please note that volume is not automatically set to 0 when it loads, but will instead reflect the volume that is set in the control panel.
int rate
This is the speed at which the voice will speak. Values range from -10 (slowest) to 10 (fastest), where 0 is normal. This is set to -1 on error. Please note that rate is not automatically set to 0 when it loads, but will instead reflect the speed that is set in the control panel.
int pitch
This is the pitch at which the voice will speak. Values range from -10 (lowest) to 10 (highest, where 0 is normal. This is set to -1 on error. The pitch is always 0 initially. Please note that some text-to-speech engines do not support pitch, in which case this property has no effect.
bool active
This is set to true if Sapi was initialised successfully, and to false otherwise. This property cannot be modified from the script.
bool speaking
This is set to true when Sapi is speaking, and to false when it is not, or if an error has occurred. This property cannot be modified from the script.
