Are Speech Engines Enough to Implement Today’s Mobile Voice Technology?

Successfully implementing a Voice Recognition (VR) system in mobile devices, isn’t always as easy as connecting a COTS speech engine to a user interface. Even though VR technology has been around for many years, its mediocre performance has mobile users still relying heavily on their keypads. However, systems employing quite accurate mobile VR technology are now layering sophisticated algorithms on top of the VR engine to add key features like ambient and impulse noise immunity, and voice-band conversational filtering, to increase VR accuracy. Software that adds value to speech engines provides a complete voice solution and these are being increasingly implemented in mobiles to make voice technology dependable in virtually any environment. So, what are the differences between implementing complete voice solutions versus speech engines alone?
