Much as I find anti-competitive behavior contemptible, this article makes a glaring, uncorroborated assumption that Google's voice-to-speech functionality is currently being held up by Apple.
Looking closer, it's not even clear that ReadWriteWeb asked either party for a comment... note: "Google’s PR response to questions like this is that “we’re working closely with Apple” on getting it released." and "Well, Apple doesn’t talk about these things, so all we know is that it isn’t out."
