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."
During the search breakfast back in early August, Google did say that they'd submitted the app. Here's a CNET article that covered the search breakfast: http://news.cnet.com/8301-1023_3-57489395-93/google-exposes-... The relevant part is "The update to the Google Search app has been submitted to Apple, and Google expects it to be approved in the next few days, Huffman said."
If anyone wants to watch Scott Huffman's demo of natural language voice search from the search breakfast, the relevant section of the video is on the web: http://www.youtube.com/watch?v=8a2VmxqFg8A#t=10m43s
Fact, you can search how much you want, you will not get a word more than that. With apple is hard to know anything about your apps let alone the app of another huge competitor.
