== getPitch, setPitch ==

Pitch can be manipulated by nvdaController_getPitch() and nvdaController_setPitch() methods.

== getRate, setRate ==

Rate (speed) can be manipulated by nvdaController_getRate() and nvdaController_setRate() methods.

== speakSpelling ==

Text can be announced using character descriptions via nvdaController_speakSpelling() method.

	time.sleep(5)
}}}

== setAppSleepMode ==

The method nvdaController_setAppSleepMode was introduced since 2014.1jp.
It controls whether NVDA should sleep or not when the application is activated.
