Hi Matthieu,
Jutoh can (theoretically) use two
methods with CereVoice - directly drive it, or use it via the
Apple Speech Synthesis Manager.
For the first method, Jutoh uses a
command-line program 'cerevoice' (adapted from a CereVoice sample)
to communicate with CereVoice, so this has to be downloaded from
the Jutoh download page and Jutoh made aware of it via
Preferences/Speech. Unfortunately I haven't kept up with versions
of CereVoice after 3, so it won't work with later ones. There is
an annual subscription to sign up for the SDK with the ability to
compile the samples (and 'cerevoice' tool). Obviously I'd like to
avoid doing that for something that is only likely to be used by
maybe one or two users and I haven't had any enquiries about it
for several years.
Perhaps you could persuade them to make
the binary 'cerevoice' tool available on their web site, which is
just a question of them compiling the simple TTS sample that takes
text and speaks it, if licensed voices are available.
Meanwhile, CereVoice should still work
with Jutoh's Apple Speech Synthesis Manager support, albeit with
slightly less functionality. Jutoh actually invokes the 'say'
command line tool which should be built into macOS - you can try
using that to test it out, and when using Jutoh, check the Log
window in case it's giving errors if it can't find 'say'. I can't
remember the specifics of configuring CereVoice to work with Apple
Speech Synthesis Manager but it should be independent of Jutoh.
Sorry not to be very helpful but perhaps others have some
experience with this; or you could contact CereVoice about making
it work on Mac.
Regards,
Julian
