What is NarTest?

	NarTest is a little utility for you to play with narrator.device.
	Includes the new features of the V37 narrator.device, so you need
	DOS2.04 (V37).

How does it work?

	It's all very simple. You use the gadgets, gadgets use the program
	and the program uses narrator.device.

How do I use it?

	First, ensure that narrator.device is in devs: and translator.library
	is in libs:, if you're using normal Workbench-disk, the files should
	be there already.
	    When you have executed the program from Workbench or CLI/Shell
	you see the programs main window. The gadgets are as follows:

	English:	Enter some text here and press <RETURN>, you should
			now see the text in phonetic form in Phonetic-gadget
			and you should hear the computer to speak the
			sentence.
	Phonetic:	You're also able to enter the text in phonetic form
			in here.
	Mode		Click to cycle between the following pitch (F0) modes:
			Natural, Robotic and Manual.
	Sex		Click to cycle between Male and Female.
	Volume		Use to set the volume between 0 and 64.
	A1adj
	A2adj
	A3adj		These three control the amplitudes of formants. Range
			is from -32db to +31db. -32db is a special value and
			shuts off that formant completely. Positive values
			may cause clipping.
	F1adj
	F2adj
	F3adj		These three change the tuning of the formant
			frequencies in ±5% steps. Range is from -20 to 20.
	F0enthus(iasm)	This one controls the scaling of pitch (F0)
			excursions. Most useful in Manual mode.
	F0perturb	The higher the value in here, the more the pitch
			(F0) shakes.
	Pitch		The baseline pitch of the voice. Range is from 65Hz
			to 320Hz.
	Rate		The speaking rate in words/minute. Range is from
			40wpm to 400wpm.
	AVBias, AFBias	These control the relative amplitudes of the voiced
			and unvoiced speech sounds. Range is from -32db to
			+31db. Again, positive values may cause clipping.
	Centphon	The vowel whose targets are used in the interpolation
			specified by Centralize.
	Centralize	This one can be used to create accent effects by
			modifying vowel sounds. Range is from 0% to 100%.
			Used together with Centphon.
	Articulate	Controls the transition time between phonemes.
	Reset Values	Sets the values back to starting values.

	To Quit click on the CloseWindow-gadget.

History

V0.95	(Saturday, 26 June 1993)
	Three days of hard work required to get the program this far. This
	is like V1.00, but the centphon/centralize-system doesn't work yet.
	The code is also quite long in here, but I might be able to optimize
	it a bit.
	Size = 6500 bytes (more or less)

V1.00	(Saturday, 26 June 1993)
	I removed a few bytes from here and a few from there and it's still
	working (though somebody could do the whole trick in some 3000 bytes?)
	Anyway, it's a bit shorter now and I finally got the centphon/
	centralize to work too, I just altered a couple of bytes and 'Goodbye
	Guru!'. Should be working fine now.
	Size = 5108 bytes

V1.01	(Sunday, 27 June 1993)
	A minor update. Now works from WB too!
	Size = 5172 bytes
