Ever since 2011, virtual voice assistants have been all the rage. First, Apple's (AAPL 0.17%) Siri came out to much fanfare, followed by Google (GOOGL -1.34%) Now. Nuance Communications (NUAN), which powers the voice recognition behind Siri, even has its own Nina assistant. Amazon.com (AMZN 0.25%) has now reportedly purchased Evi, a mobile assistant app for iOS and Android. The e-tailer has also separately acquired several small voice recognition companies over the years.
