TellMe just had their best quarter so far. It's taken them over two years to upgrade their platform to lose reliance on Nuance technology.
When TellMe was founded in 1999, they used speech recognition technology produced by the original Nuance. Over time, they upgraded their platform and continued to use Nuance technology even after ScanSoft bought out Nuance and changed it's name to Nuance.
Now, TellMe has announced vast improvements to their platform, "the most substantial ... since Microsoft bought it in May 2007." and "the improvements ... take advantage of cloud computing..."
The article states that "The improvements include speech recognition technology developed by other units of Microsoft."
