Hello Hamish

Sorry, I forgot to explain that you have to place the two lines within the
subroutine MakeVoiceFile.
As to the possible values assigned to tate and volume refer to the SAPI5
documentation (sapi.chm).

TTS Engine Characteristics

Microsoft Speech SDK
SAPI 5.1
TTS Engine Characteristics
Engines use the three characteristics of Volume, Pitch, and Rate to 
partially define speech traits. At the application level, setting these 
values is simple;
you need only set them to a given number. However, implementation of these 
traits is more complex for the engine.
Volume
At the application level, volume is a number from zero to 100 where 100 is 
the maximum value for a voice. It is a linear progression and a value of 50 
represents
half of the loudest permitted. The increments should be the range divided by 
100.
Pitch adjustment
The value can range from -10 to +10. A value of zero sets a voice to speak 
at its default pitch. A value of -10 sets a voice to speak at three-fourths 
of
its default pitch. A value of +10 sets a voice to speak at four-thirds of 
its default pitch. Each increment between -10 and +10 is logarithmically 
distributed
such that incrementing or decrementing by 1 is multiplying or dividing the 
pitch by the 24th root of 2 (about 1.03). Values outside of the -10 and +10
range will be passed to an engine. However, SAPI 5-compliant engines may not 
support such extremes and may clip the pitch to the maximum or minimum the
engine supports. Values of -24 and +24 must lower and raise pitch by 1 
octave respectively. All incrementing or decrementing by 1 must multiply or 
divide
the pitch by the 24th root of 2.
Rate adjustment
The value can range from -10 to +10. A value of zero sets a voice to speak 
at its default rate. A value of -10 sets a voice to speak at one-third of 
its
default rate. A value of +10 sets a voice to speak at three times its 
default rate. Each increment between -10 and +10 is logarithmically 
distributed such
that incrementing or decrementing by 1 is multiplying or dividing the rate 
by the 10th root of 3 (about 1.1). Values more extreme than -10 and +10 will
be passed to an engine. However, SAPI 5-compliant engines may not support 
such extremes and may clip the rate to the maximum or minimum rate the 
engine
supports.

If you are interested, I can mail you my own makevoices.vbs.
