Yes, my MakeVoice.vbs script (available at
http://arnold-j.bei.t-online.de/Rockbox/) is able to use both
SAPI5 and SAPI4 for voice file generation. The method for using
SAPI4 voices could be easy adapted for use in mp3clipgen.vbs
Although it is possible to use SAPI4 from VBScript I do not
recommend it, since the actual conversion is then done in realtime
(i.e. 1 minute conversion for a 1 minute speech), while with
SAPI5 the conversion is done as fast as the PC permits (which
should easily exceed 10x speed with a decent PC).
The "ActiveVoice" ActiveX control used by the script should allow
speed changing according to the docs, but it doesn't. Apparently
this is a bug in the control.
It should be possible to get faster-than-realtime conversion
with SAPI4 if someone writes a "real" program (VB/ VC), since
this would then use DCOM to control SAPI and not the ActiveVoice
control. I think it is not worth the effort, since the SAPI5
voices are more advanced and sound more pleasant than the SAPI4
