To have more than one SAPI 5 voice speak at once you have to use the Set
Priorety flag. It is also possible to change the pitch for a SAPI 5 voice, it
is just that most SAPI5 voices use concatnative sound samples to produce the
words, and changing the pitch of the sound samples becomes artifacty. I
realize it is an extremely hard thing to read through but the SAPI 5.1 SDK help
documentation does explain many of these things. Eloquence is a SAPI voice
only because it uses the SAPI interface to create the speech bridge. But in
that case, it is possible to create a self contained dll, much like they have
also done with E Speak for NVDA. E Speak is also a SAPI 5 voice. Narrator is
not a good example to go by in the case of good SAPI implementation, nor is the
speech control panel because it does not use the speech priorety flags. The
diference as far as responsiveness comes also by the method the voice is
synthesized. Three voices to compare are Scansoft voices, E Speak and the
standard microsoft voices. Believe it or not the microsoft voices when
programmed for correctly are quite responsive, and for some reason, Freedom
Scientific has never figured out how to do this. In fact it wasn't until
version 8 that they finally figured out how to compensate for the sample
frequency differential that SAPI 5 voices have. Now in the case of the
Scansoft voices, those voices are true recorded speech, so by nature they are
going to be slower because, in order to produce words it has to be able to
parse words, and compare it to its phonetic dictionary, then access the hard
drive to load the correct sound samples and put them together into words. The
larger the sound sample library the voice has the slower the response becomes.
In the case of E Speak it is also sampled speech, but most of its processing is
actually done through a backend synthesizer sort of like what is done with the
microsoft voices. How responsive a voice is does not really depend on whether
it is SAPI 5 or not, it depends on what method is used to synthesize the voice
and also how well done the voice coding actually is.

Does anyone know what interface is used by Eloquence?
It is not SAPI 4 nor 5, and it works better than a SAPI voice.
The problem with the SAPI voices is that at a certain moment only a single
SAPI5 voice can be active, and in order to change the voice we need to go into
Control Panel/Speech, and changing the active voice there doesn't always work.
For example, I've tried to use ESpeak sinthesizer, and I couldn't make it
active but only by deleting all others voices from the Registry.
And this was a problem also because Narrator doesn't work without those MS
made voices.
Does anyone know some books or tutorials for working with these things under
Windows? But of course, not MSDN, because it refers only to ways of creating
sinthesizers which are not used by any good company that creates sinthesizers.
Information about creating sinthesizers that work under Symbian are also
welcome.

as an extra idea, you may want to go back to
SAPI 4, and research both at MS, and on the web, (added note, if you don't
get it on Google, try web crawler, more than once, if I couldn't find it on
Google, I found it with a web crawler search)
there seems to have been more available for
SAPI 4 and it's agents, which might give you clues on how to approach it in
SAPI 5.
just a thought for you folks,

ehe!
it is not so easy even you want to make a concatenated voice not a
formant one...
I am trying now to understand how to make a voice for the language from
my country
I search for documentation, but it seems that this is a taboo subject
because I didn't find nothing how to code speach.

Well I was wondering,
Is there a program that will help you create Sapi5 voices?
Like something that you speak a number of letters into a microphone
then it gets an understanding of your voice and creates a sapi5 engine out of
it?
