Kara Swisher reported earlier today that Tellme founder Mike McCue is leaving Microsoft (s MSFT) at the end of June 2009. His Tellme co-founder, Angus Davis, is leaving the company as well. He sent out an email to his friends and family, shortly after announcing the news to the Tellme team. I’ve covered the speech-recognition company from when it was started to the day it became part of Microsoft after the software giant bought it for a rumored $800 million. Microsoft has plans to use voice as a mobile phone interface. Mike and Angus went through some serious ups and downs with Tellme. It was a deal with AT&T that helped Tellme get its mojo. I don’t think their exit disrupts Tellme’s operations. My question is, what do they do next?
