Subject: Re: Problem with win32ole, sapi5

Hi,

Does anyone have any input on this old post? I'm having the same 
problem, but I can't find any response to the post anywhere. Basically 
it seems that win32ole doesn't discover that SpVoiceInstance.Voice is 
both a gettable and settable property:

irb(main):053:0> Win32::SpVoice.new.ole_get_methods
=> [Status, Voice, AudioOutput, AudioOutputStream, Rate, Volume, 
AllowAudioOutpu
tFormatChangesOnNextSet, EventInterests, Priority, AlertBoundary, 
SynchronousSpe
akTimeout]
irb(main):054:0> Win32::SpVoice.new.ole_put_methods
=> [Rate, Volume, AllowAudioOutputFormatChangesOnNextSet, 
EventInterests, Priori
ty, AlertBoundary, SynchronousSpeakTimeout]
irb(main):055:0>

Is this a bug? The following is valid VB source code:

Set V.Voice = V.GetVoices().Item(List1.ListIndex)

So I'd expect something like this to work:

require 'win32/sapi5'
v = Win32::SpVoice.new
v['Voice'] = v.GetVoices.Item(1)

But it doesn't. I've tried all possible variants I can think of from the 
documentation:

v.Voice = ...
v.voice = ...
v.Voice(...)
v.voice(...)
v['voice'] = ...
v['Voice'] = ...
v.setproperty('voice', ...)
v.setproperty('Voice', ...)

Basically I'd really love to get this to work properly. This weeks Ruby 
Quiz inspired me to give a go at a "personal trainer" for my treadmill 
sessions here at home. For now I've settled for a tiny VB .NET command 
line app that sets the voice I want, and takes text as an argument. I'd 
really love to have an all Ruby solution for this though.
