Microsoft, not to be completely left behind also offers a pretty solid voice recognition feature for Windows Phone users called “Speech”. The good news for Windows Phone users who like or need to use Speech is that Microsoft their Speech recognition has gotten better. In fact, the “voice search and voice-to-text” features on Windows Phone 8 phones “are now up to twice as fast and 15 percent more accurate”. Unfortunately, the improvements only affect US users for now. So international users need not upgrade your phone OS anytime soon because it won’t have any effect at all.
So for US users at least, this is another excellent excuse to chunk out your old phone and “invest your finances” in a Windows 8 phone.
