Being able to communicate directly with an electronic device used to seem like a science-fiction dream. Thanks to companies like Nuance Communications ( NUAN ), though, that dream became a reality, with voice-recognition software like Apple 's ( AAPL 0.63% ) well-known Siri being staples of popular culture. Yet despite the widespread adoption of Nuance's software, the stock has suffered in recent years. Activist investor Carl Icahn has turned his attention to the company in the hopes that he can profit from the opportunities that Nuance has while encouraging its management to make better strategic decisions. With Nuance reporting fiscal fourth-quarter and full-year results on Monday, investors want to see if the company has made any progress in restoring its former growth.
