Microsoft have confirmed that the intended update to Bing and their speech-to-text service, TellMe, has now arrived on Windows Phone.
It was detailed a while back that a number of improvements would be coming such as faster searches, more accurate transcriptions and improved accuracy in noisy environments. The update means that Bing is now 2x faster and has a 15% boost in its accuracy.
You should now be able to pick up a Windows Phone and transcribe a text message, or do a Bing search, and notice the improvements that have been made. It should be noted that these changes are all on Microsoft's servers and you don't need to update your phone's OS at all.
Let us know if you notice the improvements or if you don't even plan on using the feature!
