Filemaker can speak, but to my knowledge only on Mac. It is a script step.

I've found a method by writing a script to jump to container fields, but the audio recorder is pretty crude.
Is there a plugin which allows finer editing of content and timing?
I need the built in recorder rather than a wave file as the games will be run a s standalones.
