FYI, that second link is for an android native extension. It won’t work on PC or in a browser. The first link just doesn’t load for me, but it’s the Adobe forums so that’s pretty par for the course.
There’s nothing built into Flashpunk that pertains to speech recognition, and for that reason this question really doesn’t belong on these forums. Any library that dealt with such things would be completely separate from rendering, the world-entity structure, etc, and would therefore run in parallel with your game. I don’t even know if such a thing is capable in Flash, and even if it is there’s no way to run it fast enough to keep a steady framerate.
Frankly John, this is way beyond your skill level at this time. It’s way beyond my skill level, and I’ve been programming for years. Try to keep the scope of your project small and avoid adding more pieces before you finish what you’ve already started.
