This doesn't have anything to do with Nintendo but it is video games and since Microsoft is doing this Nintendo could make voice censoring software for Wii Speak to monitor language. If they do that then they could come out with a headset because they wouldn't have to worry about people cussing on WI-Fi.

Here is the article I found here: http://www.1up.com/do/newsStory?cId=3170772

It's a well known formula: Internet plus anonymity equals jerks who will curse up a storm just for the sake of cursing. As any Xbox 360 gamer knows, it's a particularly nasty problem on Xbox Live... but has Microsoft actually developed a way to shut these fools up for good? According to Ars Technica, the United States Patent and Trademark Office has approved a patent for "automatic censorship of audio data for broadcast." Which would probably lead most reasonable people to wonder: How the f*** is that even possible?
As the description of the patent states, "an input audio data stream comprising speech is processed by an automatic censoring filter in either a real-time mode, or a batch mode, producing censored speech that has been altered so that undesired words or phrases are either unintelligible or inaudible." A more complete description of how the process works follows:

"The automatic censoring filter employs a lattice comprising either phonemes and/or words derived from phonemes for comparison against corresponding phonemes or words included in undesired speech data. If the probability that a phoneme or word in the input audio data stream matches a corresponding phoneme or word in the undesired speech data is greater than a probability threshold, the input audio data stream is altered so that the undesired word or a phrase comprising a plurality of such words is unintelligible or inaudible. The censored speech can either be stored or made available to an audience in real-time."
Elsewhere in the patent, it is explicitly stated this technology could be used for censoring chats in online games: "For certain types of broadcasts, it would be preferable to employ a more automated approach that avoids the need to pay for or provide a human censor to monitor the broadcast, while still enabling the audio data to be censored at an appropriate level. For example, in massive multiplayer games, it would be impractical to employ a human censor to monitor the multitude of voice chat sessions that might be occurring at one time."

What's most curious about this technology is the claim of it working in real-time. Chatting over Xbox Live or through something like TeamSpeak on the PC happens more or less instantly, with little delay between when you say something and when everyone else hears it (as there are during live television broadcasts, giving censors time to bleep words before they go out over the airwaves). As such, this automatic censor program would, potentially within a second, have to immediately detect an undesirable word and replace or remove it before it reaches the ears on the other line.

If this program actually works and becomes available for online games, it raises a couple of interesting questions. Would it be an optional filter? Would the ESRB make it mandatory for online games that aren't rated Mature (and once and for all remove that silly "Game experience may change during online play" warning)? What if someone speaks incoherently and the program detects and alters words that aren't actually explicit? ("So I was with my girlfriend last night, and I introduced her to funk for the first time. She enjoyed it. She enjoyed the funk all night. I mean, just wild amounts of funk all up in her ear.")
